SECTION 2: EXPRESS START UP  
The following instructions define the minimum steps necessary to make your Drive  
operational.  
Always disconnect the AC power to the unit and be certain the "PWR  
ON" LED is OFF before connecting or disconnecting the motor leads.  
FAILURE TO DO THIS RESULTS IN A SHOCK HAZARD.  
Always operate the Motor and the Drive GROUNDED. Be sure to twist  
together the wires for each motor phase. Six twists per foot is a good  
guideline.  
1. Check to see that the motor used is compatible with the drive. Refer to Section 4.4 for a  
list of compatible motors.  
2. Set the correct current level for the motor being used per the instructions in Section 4.5.  
Heat sinking may be required to maintain case temperature below +70° C (+158° F).  
3. Select the appropriate step resolution and set the front panel switches as described in Sec-  
tion 4.6.  
4. Wire the motor per the "Motor Connections" description in Section 3.2.  
5. Connect the power source to the DC input terminal strip. Be sure to follow the  
instructions for connecting the filter capacitor as described in Section 3.2, under Power  
Input.  
If the motor operates erratically, refer to Section 5, "Torque Versus Speed  
Characteristics". Clockwise and counter-clockwise directions are properly  
oriented when viewing the motor from the end opposite the mounting  
flange.

Section 3: Installation Guidelines  
3.1 MOUNTING  
The SLO-SYN Drive is mounted by fastening its mounting brackets to a flat surface as shown in  
Figure 3.1. If the drive assembly is mounted against a bulkhead, be sure to apply a thin coating of  
thermal compound between the drive and the mounting surface before fastening the unit in place.  
Do not use too much thermal compound. It is better to use too little than too much.  
Figure 3.1 Mounting Diagram  
Case temperature should not exceed +70° C (+158° F). Forced air  
cooling may be required to maintain temperature within the stated  
limits.  
When selecting a mounting location, it is important to leave at least two inches (51mm)  
of space around the top, bottom and sides of the unit to allow proper airflow for cooling.  
It is also important to keep the drive away from obvious noise sources. If possible, locate  
the drive in its own metal enclosure to shield it and its wiring from electrical noise  
sources. If this cannot be done, keep the drive at least three feet from any noise sources.

3.3.2 Power Input  
The DC input power is connected to terminals 5 and 6 of the terminal strip (J1). Terminal  
5 [Vm(+)] is the power supply plus (+) connection and pin 6 [Vom(-)] is the power  
supply minus (-) connection.  
An unregulated supply similar to that shown in Figure 3.4 is preferable. If a  
regulated supply is used, it must be capable of operating with the added filter  
capacitor. A switching regulated supply may not be suitable for use with this drive.  
It is important that the capacitor (C1) be connected within three feet (0.9 meter) of  
the input terminals. The capacitor must be of the correct value and have the proper  
current and voltage parameters (see list of components).  
It is recommended that the power supply leads be twisted together (6 twists per foot).  
If the power supply is grounded, it must only be grounded on the  
negative side or the short circuit protection will not operate properly.

SECTION 5: TORQUE VERSUS SPEED  
CHARACTERISTICS  
5.1 MOTOR PERFORMANCE  
All stepper motors exhibit instability at their natural frequency and harmonics of that frequency.  
Typically, this instability occurs at speeds between 50 and 1000 full steps per second and,  
depending on the dynamic motor load parameters, cause excessive velocity modulation or improper  
positioning. This type of instability is represented by the open area at the low end of each Torque  
vs. Speed curve.  
There are also other instabilities that cause a loss of torque at stepping rates outside the range of  
natural resonance frequencies. One such instability is broadly defined as mid-range instability.  
Usually, the damping of the system and acceleration/deceleration through the resonance areas aid in  
reducing instability to a level that provides smooth shaft velocity and accurate positioning. If  
instability does cause unacceptable performance under actual operating conditions, use the  
following techniques to reduce velocity modulation.  
1)  
2)  
3)  
Avoid constant speed operation at the motors unstable frequencies. Select a base speed  
above the motors resonant frequencies and adjust acceleration and deceleration to move  
the motor through unstable regions quickly.  
The motor winding current can be reduced as discussed in Section 4.5. Lowering the  
current reduces torque proportionally. The reduced energy delivered to the motor can  
decrease velocity modulation.  
Use the half-step mode of operation or use microstepping to provide smoother operation  
and reduce the effects of mid range instability. Microstepping reduces the shaft speed  
for a given pulse input rate.

SECTION 6: SYSTEM CHECKING  
Motors connected to this drive can develop high torque and large amounts of  
mechanical energy.  
Keep clear of the motor shaft and all parts mechanically linked to the motor shaft.  
Turn off all power to the drive before performing work on parts mechanically  
coupled to the motor.  
If installation and operating instructions have been carefully followed, this unit should  
perform correctly. If the motor fails to step properly, the following checklist will be  
helpful in locating and correcting the problem.  
In General  
Check all installation wiring carefully for wiring errors or poor connections.  
Ensure that the proper voltage levels are being supplied to the unit.  
Be sure that the motor is a correct model for use with this unit.  
Specifically  
IF MOTOR DIRECTION (CW, CCW) IS REVERSED, Check For:  
Reversed connections to the Motor Connector. Reversing the phase A or the phase B  
connections reverses the direction of motor rotation.  
IF THE MOTOR MOTION IS ERRATIC, Check For:  
Supply voltage out of tolerance.  
Proper motion parameters (low speed, acceleration/deceleration, jog speed, home  
speed and feed rate). Set parameters on controller supplying pulse input to drive.  
Filter capacitor missing or too low in value.  
IF TORQUE IS LOW, Check For:  
All Windings Off active  
Correct current setting.  
Improper supply voltage.  
IF "FAULT" INDICATOR IS NOT LIT, Check For:  
Improper motor wiring.  
Grounded or shorted wiring to the motor or shorted motor.  
Improper motor type or incorrect Current Select switch setting  
If a malfunction occurs that cannot be corrected by making the preceding checks, contact  
Customer Support.

APPENDIX A: TROUBLESHOOTING  
A.1 ELECTRICAL INTERFERENCE PROBLEMS  
Electrical interference problems are common with today’s computer-based controls. Such  
problems are often difficult to diagnose and cure. If such a problem occurs with your  
system, it is recommended that the following checks be made to locate the cause of the  
problem.  
1. Check the quality of the AC line voltage using an oscilloscope and a line monitor. If  
line voltage problems exist, use appropriate line conditioning, such as line filters or  
isolation transformers.  
2. Be certain all recommended wiring practices are followed for location, grounding,  
wiring and relay suppression (see Section 3.1).  
3. Double-check the grounding connections to be sure they are good electrical  
connections and as short and direct as possible.  
4. Try operating the drive with all suspected noise sources switched off. If the drive  
functions properly, switch the noise sources on again, one at a time, and try to isolate  
the one(s) causing the interference problems. When a noise source is located, try  
rerouting wiring, suppressing relays or other measures to eliminate the problem.
