WARNING - ELECTRICAL SHOCK AND BURN
WARNING / ATTENTION:
HAZARD / ATTENTION – DÉCHARGE ÉLECTRIQUE ET
Adjustable frequency drives are electrical apparatus for
use in industrial installations. Parts of the drives are
energized during operation. The electrical installation, tune-
up and troubleshooting should therefore only be carried
out by qualified personnel. Improper installation of motors
or drives may cause the failure of the drive as well as
serious injury to persons or equipment. The drive is not
equipped with motor overspeed protection logic.
RISQUE DE BRÚLURE :
When using instruments such as oscilloscopes to work
on live equipment, the oscilloscope’s chassis should be
grounded and a differential input amplifier should be used.
Care should be used in the selection of probes and leads
so that accurate readings may be made. See the
instrument manufacturer’s instruction book for proper
operation and adjustments of the oscilloscope.
Follow the instructions given in this manual and observe
the local and national safety regulations applicable.
Lors de l’utilisation d’instruments (par example
oscilloscope) sur des systémes en marche, le chassis de
l’oscilloscope doit être relié à la terre et un amplificateur
différentiel devrait être utilisé en entrée.
Les drives à fréquence variable sont des dispositifs
électriques utilisés dans des installations industriels. Une
partie des drives sont sous tension pendant l’operation.
L’installation électrique et l’ouverture des drives devrait être
executé uniquement par du personel qualifié. De mauvaises
installations de moteurs ou de drives peuvent provoquer
des dommages materiels ou blesser des personnes.
Les sondes et conducteurs doivent être choissis avec soin
pour effectuer les meilleures mesures à l’aide d’un
oscilloscope. Voir le manuel d’instruction pour une
utilisation correcte des instruments.
WARNING - FIRE AND EXPLOSION HAZARD /
ATTENTION – RISQUE D’INCENDIES ET
D’EXPLOSIONS:
Le convertisseur n’est pas pourvu de protection contre
vitesse de fuite du moteur. On doit suivir les instructions
donneés dans ce manuel et observer les régles nationales
de sécurité.
Fires or explosions might result from mounting drives in
hazardous areas such as locations where flammable or
combustible vapors are present. Drives should be installed
away from hazardous areas, even if used with motors
suitable for use in these locations.
CAUTION / PRECAUTION:
Do not connect power supply voltages that exceeds the
standard specification. If excessive voltage is applied to
the drive, damage to the internal components will result.
L’utilisation des drives dans des zônes à risques (présence
de vapeurs ou de poussières inflammables), peut provoquer
des incendies ou des explosions. Les drives doivent être
installés loin des zônes dangeureuses, et équipés de
moteurs appropriés.
Ne pas raccorder de tension d’alimentation dépassant la
fluctuation de tension permise par les normes. Dans le cas
d’ une alimentation en tension excessive, des composants
internes peuvent être endommagés.

CAUTION / PRECAUTION:
Lors du déballage du drive, retirer le sachet déshydraté.
(Si celui-ci n’est pas retiré, il empêche la ventilation et
provoque une surchauffe du drive).
Do not operate the drive without a ground wire being
connected. The motor chassis should be grounded to

d’un instrument de serrage specifié par le producteur du
connecteur.
Les mots “inverter”, “controller” et “drive” sont
interchangeables dans le domaine industriel. Nous
utiliserons dans ce manuel seulement le mot “drive”.
1. Never open the device or covers while the AC Input power supply
is switched on. Minimum time to wait before working on the
terminals or inside the drive is listed in section 4.11 in the Instruction
manual .
CAUTION / PRECAUTION:
Do not perform a megger test between the drive terminals
or the control circuit terminals.
Ne jamais ouvrir l’appareil lorsqu’il est suns tension. Le temps
minimum d’attente avant de pouvoir travailler sur les bornes ou bien
à l’intérieur de l’appareil est indiqué dans la section 4.11 (Instruction
manual).
Ne pas exécuter un test megger entre les bornes du drive
ou entre les bornes du circuit de contrôle.
2. Be careful not to the damage any components when handling the
drive. Changing of the isolation gaps or removing the insulation or
covers is not permissible. If the front cover has to be removed
because of a room temperature, higher than 40°C, the user has to
ensure that no occasional contact with live parts may occur.
CAUTION / PRECAUTION:
Because the ambient temperature greatly effects drive life
and reliability, do not install the drive in any location that
exceeds the allowable temperature. Leave the ventilation
cover attached for temperatures of 104° F (40° C) or below.
Manipuler l’appareil de façon à ne pas toucher ou endommager
des parties. Il n’est pas permis de changer les distances d’isolement
ou bien d’enlever des matériaux isolants ou des capots. Si la plaque
frontale doit être enlevée pour un fonctionnement avec la
température de l’environnement plus haute que 40°C, l’utilisateur
doit s’assurer, par des moyens opportuns, qu’aucun contact
occasionnel ne puisse arriver avec les parties sous tension.
Étant donné que la température ambiante influe sur la vie
et la fiabilité du drive, on ne devrait pas installer le drive
dans des places ou la temperature permise est dépassée.
Laisser le capot de ventilation en place pour températures
de 104°F (40°C) ou inférieures.
3. Protect the drive from extreme environmental conditions
(temperature, humidity, shock etc.)
CAUTION / PRECAUTION:
Protéger l’appareil contre des effets extérieurs non permis
(température, humidité, chocs etc.).
If the drive’s Fault Alarm is activated, consult the
TROUBLESHOOTING section of this instruction book.
Correct the problem before resuming operation, automatic
reset of faults is not recommended.
4. No voltage should be connected to the output of the frequency
inverter (terminals U2, V2 W2). The parallel connection of several
drives via outputs nor the direct connection of inputs and outputs
(bypass) are not permissible.
Si la Fault Alarm du drive est activée, consulter la section
du manuel concernant les défauts et après avoir corrigé
l’erreur, reprendre l’opération. Ne pas réiniliatiser l’alarme
automatiquement par une séquence externe, etc….
Aucune tension ne doit être appliquée sur la sortie du convertisseur
(bornes U2, V2 et W2). Il n’est pas permis de raccorder la sortie de
plusieurs convertisseurs en parallèle, ni d’effectuer une connexion
directe de l’entrée avec la sortie du convertisseur (Bypass).
CAUTION / PRECAUTION:
5. When engaging a running motor, the Auto capture function (Auto
capture in the ADD SPEED FUNCT menu) must be activated (not
applicable to Regulation mode=sensorless vect).
Be sure to remove the desicant dryer packet(s) when
unpacking the drive. (If not removed these packets may
become lodged in the fan or air passages and cause the
drive to overheat).
Pour reprendre des moteurs en rotation, la fonction suivante doit
être activée : “Auto capture” dans le menu ADD SPEED FUNCT.

6. A capacitative load (e.g. variable power factor capacitors) should
not be connected to the output of the drive (terminals U2, V2, W2).
9. No dielectric tests should be carried out on parts of the drive. A
suitable measuring instrument (internal resistance of at least 10
kΩ/V) should be used for measuring the signal voltages.
Aucune charge capacitive ne doit être connectée à la sortie du
convertisseur (bornes U2, V2 et W2) (par exemple des condensateurs
de mise en phase).
Il ne faut pas éxécuter de tests de rigidité diélectrique sur des
parties du convertisseurs. Pour mesurer les tensions, des signaux,
il faut utiliser des instruments de mesure appropriés (résistance
interne minimale 10 kΩ/V).
7. Always connect the drive to the protective ground (PE) via the
marked connection terminals (PE2) and the housing (PE1).
Adjustable Frequency Drives and AC Input filters have ground
discharge currents greater then 3.5 mA. EN 50178 specifies that
with discharge currents greater than 3.5 mA the protective conductor
ground connection (PE1) must be a fixed type and doubled for
redundancy.
10. If the drives have been stored for longer than three years, the
operation of the DC link capacitors may be impaired. Therefore,
before commissioning, connect them to a power supply for two
hours with no load connected in order to regenerate the capacitors
(the input voltage has to be applied without enabling the drive).
Effectuer toujours des connexions de terre (PE) par le biais des
bornes (PE2) et du chassis (PE1). Le courant de dispersion vers la
terre est supérieur à 3,5 mA. Selon EN 50178 il faut prévoir dans
ces cas une double connexion à terre.
En cas de stockage des convertisseurs pendant plus de trois ans, il
faut tenir compte du fait que les condensateurs du circuit
intermédiaire gardent leurs caractéristiques d’origine seulement s’ils
sont alimentés avant trois ans, à partir de leur date de fabrication.
Avant la mise en service des appareils, qui sont restés stockés aussi
longtemps, il est conseillé d’alimenter les convertisseurs pendant
au moins deux heures, pour récupérer les caractéristiques d’origine
des condensateurs : appliquer une tension d’entrée sans activer le
convertisseur (Disable).
8. The electrical commissioning should only be carried out by quali-
fied personnel, who are also responsible for a suitable ground
connection. The power supply feeder must be in accordance with
the local and national regulations. The motor must be protected
against overloads.
11. The drive may start accidentally because of a failure, even if
disabled, unless it has been disconnected from the AC input feeder.
La mise en service électrique doit être effectuée par un personnel
qualifié. Ce dernier est responsable de l’existence d’une connexion
de terre adéquate et d’une protection des câbles d’alimentation
selon les prescriptions locales et nationales. Le moteur doit être
protégé contre la surcharge
L’appaeil peut rédémarrer de façon accidentel en cas d’anomalie,
sauf s’il a été déconnecté du reseau.

2. Overview
Underline: When words are underlined, they refer to a
key on the keypad.
This guide assumes a standard start up using the keypad
for a drive and motor that is to be run in either sensorless
vector or flux vector (with digital or sinusoidal encoder)
mode. It is also assumed that a standard scheme is to be
used for control. In other words, that the drive will be run
from pushbuttons (or contacts) and the speed will be set
from a pot input (or a 0 to 10 VDC source). While the drive
has more modes of operation, this guide will cover most
applications. The manual can be used to help adjust more
complicated configurations.
Quotes: Quote marks are put around words which will be
seen in the display window of the keypad.
Menu Navigation: In the instructions, you will be directed
to press keys to get to certain menu items. In many cases,
the same key will have to be pressed more than once to
get to a value. Note that the display has two lines, the top
line always shows the next HIGHER level of the menu. All
of the menu items referred to in this start up will be shown
in the SECOND LINE of the display. The display on the top
line is for information only and has nothing to do with
entering data. If the instructions say to press the [Down
arrow] to “Regulation Mode” it means keep pushing the
[Down arrow] until the “Regulation Mode” is displayed in
the second line. If you get confused, refer to the manual
as it shows the complete menu structure.
Standard Wiring: see the manual for the standard wiring
configuration. Note that if this is a system designed and
wired by our factory, the set up of the drive (aside from
minor tuning) has already been done.
NOTE:
Memory: There are two memories for set-up parameters.
One is the active memory which is always the one currently
in use by the drive. The other is the permanent memory
which is the one the drive will use if power is lost and then
restored. Note: power up is the ONLY time when the drive
looks at permanent memory. All file uploads and
downloads, all changes, etc. are made only to the active
memory and read from the active memory. The only time
permanent memory is used in any way is when it is booted
into active memory on power up, and when it is changed
to new values by the “Save Parameters” command. When
parameters are changed during set-up, the drive will use
those parameters but unless the “SAVE
PARAMETERS”command is used these changes will not
be permanent. This is an advantage if you are “trying”
something to see how it works and don’t intend to change
your permanent set-up.
I/O Connections: the drive WILL NOT OPERATE unless
the hardware enable (I/O terminal 12) and the other
interlocks are made. It is suggested to make things simple,
to temporarily connect the terminal board inputs as follows:
Jumper 16 to 18, jumper 19 to 15, jumper 15 to 14, jumper
12 to 13, and connect a simple switch between 13 and 14.
Turning the switch on and off will now enable and disable
the drive (and start and stop it at the same time). If you
have control over the I/O with the connected logic and
can make the same connections with pushbuttons/
contacts, the drive can be enabled with those.

7. Pre Power Checks
The following should be checked before switching ON the Drive:
Grounds / Grounding
•
•
Verify ground connections between the drive and motor
Verify AC Input, AC Output and control wiring aren’t grounded
Connections
Verify AC Input (U1/L1, V1/L2, W1/L3), AC Output (U2/T1, V2/T2, W2/T3), DC link connection (C,D), Motor thermistor
(78, 79), OK Relay (80, 82), Relay 2 (83,85) and regulation board points (1.....46, XS, XE) connections.
•
Regulator Terminal Board Inputs:
12 ENABLE DRIVE (close to activate)
13 START (close to activate)
14 FAST STOP (open to cause a stop)
15 EXTERNAL FAULT (open to cause a stop)
16 Common for terminal board inputs
18 + 24V Common
19 +24VDC (internal power supply)
Set inputs on the regulator terminal board as follows:
• Enable drive (terminal 12) and Start (terminal 13) OPEN
• Fast stop (terminal 14) and External fault (terminal 15) CLOSED
• Record motor name plate data, encoder information, gearbox data.

the display is the correct motor voltage, then [Enter].
For 460 VAC motors, select 460, and for 380/400 VAC
motors select 400.
8. Quick tuning
1. After a complete check of wiring, turn the power on:
•
The following voltages must be present:
6. Set Actual Motor Data:
Terminal 7, +10V to terminal 9 (on regulation board)
Terminal 8, -10V to terminal 9 (on regulation board)
•
Press [Left arrow] until back to “Drive parameter”,
then [Enter] to get “Mot plate data” and [Enter] to
“Nominal Voltage” then [Enter] again to see the value.
Using the [Up arrow]/[Down arrow] keys to change
the value and the [Left arrow] to move the character
position. When correct press [Enter].
Terminal 19, +24…30V to terminal 18 (on regulation
board)
•
Check DC link voltage by pressing [Down arrow] to
get “Monitor”, then [Enter], then [Down arrow]
to“measurements”, then [Enter], then [Down arrow]
to “DC link voltage”, then [Enter].
•
Press [Down arrow] to “Nominal speed”, [Enter], then
use the [Up arrow] / [Down arrow] keys to get the
nominal speed on the motor nameplate. Press [Enter]
to set data. Note, some manufacturers of vector
motors put the synchronous speed (600, 900, 1500,
1800, 3600 RPM), rather than the slip speed at 60 Hz
on the nameplate. If this is done, you MUST estimate
slip speed. Figure 20 rpm less than the synchronous
speed for these cases.
The value should be:
275-357 VDC for 230 VAC input
480-650 VDC for 400 VAC input
550-715 VDC for 460 VAC input
If the DC Bus is not within these limits, check the AC
line voltage.
•
•
Press [Down arrow] to “Nom frequency” and [Enter]
and set to the nominal frequency on the nameplate
(50 or 60 Hz) Press [Enter] to set data.
2. Default to Factory Values: If you are not certain of the
drive configuration, it will be necessary to default to factory
values or copy in a file from a PC. It is important to be
certain you are starting from a known configuration. To
default to factory values:
Press [Down arrow] to “Nominal current” and [Enter]
and set to the nominal current on the nameplate (rated
current) by using the [Up arrow] / [Down arrow] keys.
Press [Enter] to set data.
•
Default to working memory: Push [Left arrow] to
get back to “Monitor”, then [Down arrow] to “Spec
Functions” and then [Enter]. Push [Down arrow] to
“Load Default” and [Enter]. The factory values will
now be loaded into the working memory, the original
values are still in permanent memory.
If the drive will “not accept” the value entered, the
most common cause is trying to [Enter] a value for
“Nominal Current” that is less than 30% of the drive
rating. This is not allowed due to parameter problems
encountered with a small motor and a large drive. Go
back to step 6 and repeat the entries. If this doesn’t
work, see the Overflow List in the troubleshooting
section of this book.
Note:
Step 2 can be skipped if you know that the drive is loaded
with factory defaults (as it comes out of the shipping
carton).
•
Press [Down arrow] to “Cos phi” and [Enter] and set
the nominal power factor on the nameplate by using
the [Up arrow] / [Down arrow] keys (accept the
default if you don’t know). Press [Enter] to set data.
3. Set Line Voltage:
•
Press [Left arrow] to “Spec functions” then [Up
arrow] to “BASIC MENU”, then [Enter], then [Down
arrow] to “Drive type”, then [Enter] to “Mains voltage”
and [Enter]. Now using the [Up arrow] / [Down
arrow] keys, change the voltage to your nominal AC
input rating. Then [Enter] to set the value.
Press [Down arrow] to “Base Voltage” and [Enter]
and set the base voltage by using the [Up arrow] /
[Down arrow] keys (usually rated voltage). Press
[Enter] to set data. Look in the manual for both Base
Voltage and Base Frequency when operating the motor
above normal synchronous speed.
4. Adaption to maximum ambient temperature:
•
Press [Down arrow] to “Ambient temp” then [Enter].
Now using the [Up arrow] / [Down arrow] keys, set
the maximum ambient temperature value: 40°C or
50°C, then [Enter].
•
•
Press [Down arrow] to “Base Frequency” and [Enter],
set to the base frequency by using the [Up arrow] /
[Down arrow] keys (usually rated frequency). Press
[Enter] to set data.
5. Load Default Motor Values:
Press [Down arrow] to “Take motor par” and [Enter]
and set all the motor parameters. If, when you do
this, a message saying “Over-range error XXX”
appears, there is something wrong with the data
you have entered. The drive has NOT ACCEPTED

13. Self Tune part 2:
Press [Down arrow] four times to “Refresh Enc 1”
then [Enter], “Enable” [Enter], this enables the Speed
fdbk Loss Alarm.
The initial part of self tuning that can be done without
the motor rotating has been accomplished. Now, to
get the best possible tuning, the motor needs to turn
with no load attached to the shaft. For this we use
Self tune mode 2a. If, for any reason, the motor cannot
be made to rotate with no load, then a “close” level of
tuning can still be accomplished by selecting Self tune
mode 2b.

Max Amount”, and [Enter]. Change the value from
5000 RPM to the maximum speed of the motor use
the [Up arrow]/[Down arrow] keys as before (for now
set it to 105% of the rated motor speed). Press
[Enter].
•
Now press [Left arrow] to see “self tune 1” then
[Down arrow] to “self tune 2a or 2b and press [Enter].
Enable the drive using the switch to terminal 12. Press
[Enter], “start part 2a ?” or “start part 2b ?” then
[Enter] and see “measure sat 2a (or b)” will appear
and the motor shaft will turn (if “self tune 2a” is select).
Wait until the display says “end”, press [Left arrow]
to see “self tune 2a (or b)” then [Enter] and press
[Down arrow] to see “take val part 2a (or b)”. Disable
the drive (switch off terminal 12), then [Enter].
10. Prepare for Self Tune:
•
The keypad will be used for this purpose but the
I/O needs to be connected properly to the enable/
disable functions.

NOTE:
•
Set the current limit (BASIC MENU\ T Current lim +/-)
to a value compatible with the motor size and load.
(Example when motor is 1/3 of the Drive power, the
limit should be reduced compared to the default value).
“xxx range error” or “timeout” messages may also occur in
some extreme parameter ranges. Repeat the tune in this
case. If error messages are persistent see troubleshooting
section.
•
•
Select the torque current value to be used during the
test via the Test T curr lim parameter
If there was some reason you did not want to keep these
values permanently, but only wanted to try to run the drive
with them, there is no need to save them to permanent
memory. If power is cycled however, these values will be
lost unless the “Save Parameter” function is used.
Now press [Left arrow] to see “self tune 2a or 2b”
then [Down arrow] to “self tune 3” and press [Enter]
to Fwd-Rev spd tune, then [Enter]. Set the motor shaft
direction for this test: Forward or Reverse by using
[Up arrow] / [Down arrow] keys. Press [Enter] to
set the selection.
14. Self tune part 3:
The third part of self tuning (Speed regulator tuning)
identifies the total inertia at the motor shaft, the friction
value and computes the proportional and integral gains
of the speed regulator. The motor needs to be free to
turn with load attached to the shaft.
•
Enable the drive using a switch on terminal 12 [and
close terminal 13 to terminal 19 if Speed control
function is enabled (default)]. Press [Down arrow]
to “Start part 3” then press [Enter], “start part 3 ?”
then [Enter] and see “measure speed” will appear and
the motor will turn. Wait until the display says “end”,
press [Left arrow] to see “self tune 3” then [Enter]
and press [Down arrow] to see “take val part 3”.
Disable the drive, then [Enter]. You are now finished
with the initial set up and tuning with values stored in
only in the “working memory”.
NOTE:
When regulation mode = field-oriented, the encoder needs
to be verified before running Self Tune 3. Refer to page 22
“Encoder Verification”. After this verification procedure, put
the regulation mode back to field oriented.
WARNING !
NOTE:
This procedure requires free rotation of the motor shaft
coupled to the load. The Start/Stop command is
ignored, therefore it can not be used on drives with
limited travel, or when free rotation presen ts a safety
problem.
“xxx range error” or “timeout” messages may also occur
in some extreme parameter ranges. Repeat the tune in
this case. If error messages are persistent see
troubleshooting section.
CAUTION !
NOTE:
The test is performed using the torque limit value set
in Test T curr lim parameter. The torque is applied in a
step fashion, with no ramp profile. Therefore, the
mechanical transmission must not have significant
backlash, and it must be compatible with operation at
the torque limit set in the Test T curr lim parameter.
The user can reduce the torque limit to a suitable value
via the Test T curr lim parameter.
If there was some reason you did not want to keep these
values permanently, but only wanted to try to run the drive
with them, there is no need to save to permanent memory.
If power is cycled however, these values will be lost unless
the next step is taken.
To save all values to permanent memory, select Save
parameters and press [Enter] .
Note !
15.Set up for Running:
•
Application where the system inertia coupled to the
motor shaft is much higher than the motor inertia value
, increase the Test T curr lim parameter to avoid “Time
out” error.
First, before saving, let’s put the drive into the
configuration you want to run it in.
The drive is factory setting to run through the Increase

be grounded, and should be grounded somewhere,
preferably at the load device (meter).
Encoder verification: Set the Drive in V/f mode and run
the motor, enable and start the drive and set an analog
reference. If the reference is positive on terminal 1 with
respect to 2 (common) the motor should be turning
clockwise. With the motor turning clockwise (looking at
the drive end), monitor the encoder measurement by
selecting “Monitor/measurements/speed/speed in rpm/
Enc 1 speed”. The speed should be positive, not negative.
If it is negative, then A and A- or B and B- should be
interchanged on the encoder. Now return to the “Set Up
for Running” section.
How to disable analog input 1 as ramp reference:
Analog inputs 2 and 3 are defaulted to off, #1 is defaulted
to Ramp ref 1.
•
Press [Up arrow]/[Down arrow] to “I/O Config”, then
[Enter].
•
Press [Down arrow] to “Analog inputs”, then [Enter]
for Analog input 1, then [Enter] to Select input 1, then
[Enter] to display the setting, which will be “Ramp ref
1”.
Current Limit: The current limit will have been set to
approximately 136% by default in the previous setup (exact
number is a function of the power factor but the difference
is very small). The value actually set can be verified by
(from “Basic Menu”) pressing down/right arrow to “Limits”,
then [Enter], then down/right arrow to “current limits”, then
[Enter], then down right arrow to “T current lim” and [Enter].
The value of T current limit can be changed to a higher (or
lower) number. Bear in mind that the ultimate limits are
based on the capacity of the drive, not the motor. T current
is the torque producing component of total current. Settings
in excess of 200% are possible, although the motor may
not be able to handle this current. Current Limit restricts
the magnitude of the torque current reference. The drive
has other alarms and faults to provide motor and drive
current protection.

then [Enter] again to see the set up. It says “OFF”.
Use the [Up arrow] / [Down arrow] keys to display
“Ramp ref 1” and [Enter]. This means the analog input
2 (terminals 3 and 4) will be the ramped (accel/decel)
speed reference for the drive.
The manual shows the entire configuration of other
I/O in the drive.
I/O Configuration: This drive can be configured in several
10. Quick Tuning Guide for Factory
Configured (or pre-configured)
Drives
ways.
The standard drive has three standard analog inputs and
two analog outputs as well as six digital inputs and two
digital outputs. These are assignable and configurable. The
drive is defaulted already to provide the analog outputs
as Actual speed and Torque current. To set up the drive
for two analog outputs (one for speed and one for load)
for metering or other purposes, do the following:
When the drive configuration has already been set and
you are simply fine tuning the drive you can ignore most of
the preceding procedure. It is recommended that you go
through the steps anyway, if the data is suspect. You can
just use the [Left arrow] key rather than the [Enter] key in
all the steps in which the entry is found to be correct. Start
with step 4 of the full procedure and do not default the
parameters to factory parameters. If there is any
question about whether the existing setup should be saved
or not, then use the configuration tool software that came
with the drive and save the file to a PC first so it can be
used later.
Refer to the “Control terminals” section of this guide
showing a description of the connections to the regulator.
A more detailed description and discussion of the I/O are
shown in the manual. The analog outputs are defaulted to
a scale of 1, which means 10 volts out at the max parameter
value. In other words, if analog output 1 is set to max speed
then max speed will be scaled to 10 VDC (maximum output
voltage available) at “Speed Base Value”. If you wanted 5
volts out at max speed then set the scale to 0.5. If the
output were set to Torque current then 10 VDC would be
rated current. If you wanted the output to be 10 Vdc at
150% of “Full Load Current” then the scale would be 0.66.
The standard factory default is already set up for speed
(with scale factor of 1) on analog output 1 (terminals 21
and 22) and load (Torque current, with scale factor of 1) on
analog output 2 (terminals 23 and 22). Note that terminal
