PAS4S  
2.3  
Basic information  
@ WARNING  
GREAT MASS OR FALLING PARTS  
Consider the mass of the axis when mounting it. It may be neces-  
sary to use a crane.  
Mount the axis in such a way (tightening torque, securing screws)  
that the axis and mounted parts cannot come loose even in the  
case of fast acceleration or continuous vibration.  
Note that vertically installed linear axes may lower unexpectedly.  
Failure to follow these instructions can result in death, serious  
injury or equipment damage.  
@ WARNING  
LOSS OF CONTROL  
The designer of any control scheme must consider the potential  
failure modes of control paths and, for certain critical functions,  
provide a means to achieve a safe state during and after a path  
failure. Examples of critical control functions are EMERGENCY  
STOP, overtravel stop, power outage and restart.  
Separate or redundant control paths must be provided for critical  
functions.  
System control paths may include communication links. Consid-  
eration must be given to the implication of unanticipated transmis-  
sion delays or failures of the link.  
Observe the accident prevention regulations and local safety  
guidelines.  
1)  
Each implementation of the product must be individually and thor-  
oughly tested for proper operation before being placed into serv-  
ice.  
Failure to follow these instructions can result in death or serious  
injury.  
1) For USA: Additional information, refer to NEMA ICS 1.1 (latest edition), Safety  
Guidelines for the Application, Installation, and Maintenance of Solid State Control

1) In the case of axes with more than one carriage, you must add the carriage length (LC) and the distance between the carriages  
for each additional carriage. More than 1 carriage on request.  
2) Prepared for locating rings (see Accessories)  
3) The stroke reserve must be increased depending on the application factors load, acceleration and velocity. The displacement dis-  
tances must be taken into account in terms of the total length.

Figure 3.10 Forces and torques  
The service life of the axis (in km) can be approximated using the load-  
ing factor and the service life - load characteristic curve.  
The application-specific load values appear in the numerator.  
The numerator contains the maximum permissible forces and torques.  
These forces and torques decrease at increasing velocities, see char-  
acteristic curves in chapter 3.  
3.6  
Positioning accuracy and repeatability  
Positioning accuracy and repeatability depend on temperature, load and  
velocity changes as well as the accuracy of the ball screw drive and the  
accuracy of the switching points of the sensors.  
At steady temperature, speed and load, the repeatability amounts to  
0.02 mm.

@ WARNING  
GREAT MASS OR FALLING PARTS  
Consider the mass of the axis when mounting it. It may be neces-  
sary to use a crane.  
Mount the axis in such a way (tightening torque, securing screws)  
that the axis and mounted parts cannot come loose even in the  
case of fast acceleration or continuous vibration.  
Note that vertically installed linear axes may lower unexpectedly.  
Failure to follow these instructions can result in death, serious  
injury or equipment damage.  
@ WARNING  
MOTOR WITHOUT BRAKING EFFECT  
If power outage and faults cause the power stage to be switched off,  
the motor is no longer stopped by the brake and may increase its  
speed even more until it reaches a mechanical stop.  
Verify the mechanical situation.  
If necessary, use a cushioned mechanical stop or a suitable hold-  
ing brake.  
Failure to follow these instructions can result in death, serious  
injury or equipment damage.  
@ CAUTION  
HOT SURFACES  
Depending on the operation, the surface may heat up to more than  
100°C (212°F).  
Do not allow contact with the hot surfaces.  
Do not allow flammable or heat-sensitive parts in the immediate  
vicinity.  
Consider the measures for heat dissipation described.  
Check the temperature during test runs.  
Failure to follow these instructions can result in injury or equip-  
ment damage.

4.1  
Preparing installation  
The linear axis is a precision product and must be handled with care.  
Shocks and impacts may damage the guides and the ball screw drive.  
This may cause inaccuracies and even premature failure.  
Transport the product in its packaging as close as possible to the instal-  
lation site. Do not remove the packaging until the product is at the instal-  
lation site.  
The linear axis may only be lifted at points A and B (see figure). The dis-  
tance between the end block and point A and between the end block and  
point B should be ¼ of the total length of the linear axis. If an axis with  
a mounted motor is lifted, points A and B are to be moved to balance the  
load. The motor must not be used to lift the load. However, support the  
motor when lifting the axis.

Mechanical installation  
Accessibility for servicing When mounting the linear axis, the motor and the sensors, keep in mind  
that they may have to be accessed for servicing.  
Mounting position The linear axis can be installed in any position.  
If a linear axis with a mounted motor is mounted in a vertical position, the  
motor should be at the top. This way, the ball screw is under tension and  
there is no buckling stress.  
4.2.1 Standard tightening torques  
Special tightening torques are applicable for mounting sensors and  
elastomer couplings; these tightening torques are listed in the appropri-  
ate chapters.  
The following, generally applicable tightening torques apply to mounting  
the payload and fastening slot nuts, clamping claws, motor and contact  
plate with hex socket screws.

4.2.2 Mounting the linear axis  
Only mount the linear axis using the T slots at the axis body. To do so,  
use clamping claws (lateral fastening) or slot nuts (bottom or lateral fas-  
tening).  
A selection of suitable clamping claws and slot nuts can be found in  
Note the following:  
When using motors with a cross section greater than the cross sec-  
tion than the axis body, the axis must be supported or the mounting  
surface must be cut out as required.  
The end blocks protrude beyond the axis body at the ends. The end  
blocks must not be the only parts supported by the mounting sur-  
face.  
If the lateral slots are used for mounting, the sensor cable cannot be  
completely routed in the slots.

4.2.4 Mounting the sensors  
@ WARNING  
LOSS OF CONTROL  
If unsuitable sensors are installed, ground faults or line interruptions  
will be detected as an On state and will cause a failure of the protec-  
tion function.  
If possible, use normally closed contacts as limit switches so that  
a wire break can be signaled as an error.  
Failure to follow these instructions can result in death, serious  
injury or equipment damage.  
A sensor is mounted to the axis body by means of a sensor holder. The  
axis body provides a T slot for the sensor holder. This T slot has a cutout  
at the end block for inserting the fastening nuts.  
Unless otherwise specified, the standard tightening  
torques indicated on page 47 apply.  
Before mounting See chapter 7 "Accessories and spare parts" for suitable sensors.  
You need a set of Allen keys and a feeler gauge.  
̈ Clean all parts you will use.  
̈ Check all parts for damage; repair damages.  
̈ Check the sensor for correct type and function.  
̈ Verify that your controller and your interface are suitable for the sen-  
sor.  
̈ See the dimensional drawings in chapter 3 "Technical Data" for  
information on the sensor position..  
Procedure

Since the sensor operates inductively, the switching surface must have  
a specific distance from the contact plate. This so-called "switching dis-  
tance" amounts to 0.5 0.1 mm.  
̈ Move the carriage until the contact plate is above the sensor holder.  
̈ Slide the sensor through the sensor holder opening until the switch-  
ing distance has been reached.

@ DANGER  
ELECTRIC SHOCK  
High voltages at the motor connection may occur unexpectedly.  
Verify that no voltage is present (this includes the DC bus) prior to  
taking up work on the drive system.  
AC voltage can couple voltage to unused conductors in the motor  
cable. Insulate both ends of unused conductors in the motor  
cable.  
The motor generates voltage when the shaft is rotated. Prior to  
performing any type of work on the drive system, block the motor  
shaft to prevent rotation.  
Failure to follow these instructions will result in death or serious  
injury.  
@ WARNING  
GREAT MASS OR FALLING PARTS  
Consider the mass of the axis when mounting it. It may be neces-  
sary to use a crane.  
Mount the axis in such a way (tightening torque, securing screws)  
that the axis and mounted parts cannot come loose even in the  
case of fast acceleration or continuous vibration.  
Note that vertically installed linear axes may lower unexpectedly.  
Failure to follow these instructions can result in death, serious  
injury or equipment damage.

Maintenance  
The maintenance intervals for cleaning and lubrication must be adhered  
to.  
̈ Include the maintenance intervals in your maintenance schedule.  
8.2.1 Cleaning  
Due to its design, the product is not susceptible to the ingress of con-  
taminants and external objects. The guide is located inside the axis body  
and it is covered.  
The product must be inspected and cleaned at regular intervals.  
̈ Do not use compressed air for cleaning.  
̈ Remove large particles and dirt from the surface at regular inter-  
vals.  
̈ The anodized surface only has a limited resistance to alkaline  
cleaning agents. Therefore, use only neutral cleaning agents for  
cleaning.  
̈ Use only damp, soft and lint-free cleaning cloths to wipe the sur-  
face.  
Cover strip The cover strip is teflon-coated. The friction causes abrasion on the  
cover strip.  
̈ Remove abrasion products at regular intervals.

8.2.2 Lubrication  
CAUTION  
DAMAGE DUE TO WRONG LUBRICANT  
Wrong lubricants may damage the product.  
Use the correct type of lubricant (grease, oil) as required by  
the linear guide of the linear axis.  
Note the type code.  
Failure to follow these instructions can result in equipment  
damage.  
Lubricant is used continuously during operation of the linear axis. There-  
fore, regular relubrication is mandatory.  
The lubrication system is not completely tight. Therefore, small amounts  
of lubricants may escape after relubrication.  
Insufficient lubrication or incorrect lubricants increase wear and reduce  
the service life. The following factors influence the lubrication intervals:  
Dust and dirt particles  
High operating temperatures  
Heavy loads  
Heavy vibration  
Permanent short-distance positioning  
High speed of rotation of ball screw

8.2.3 Lubricating the linear guide and the drive elements  
The ball screw axis is lubricated with grease from an internal reservoir.  
The reservoir is factory-prefilled. The carriage features 3 grease nipples  
at each side for relubrication.  
The outer grease nipples are used to lubricate the linear guide.  
The inner grease nipples are used to fill the drive element (ball  
screw drive).  
The lubrication interval depends on the load, the velocity, the cycle time  
and the ambient conditions. The following recommended values apply to  
lubrication intervals:

See chapter 7 "Accessories and spare parts" for grease guns, nozzles  
and lubricants.  
Notes on greasing When applying the lubricant, you must not exceed a maximum flow rate.  
Therefore, the minimum injection time of 3 seconds per grease gun  
stroke must be adhered to.  
The carriage must be moved between strokes of the grease gun to allow  
the grease to distribute evenly in the lubricant reservoirs.

9.1  
Terms and Abbreviations  
Axis body The axis body is a high-strength, torsion-resistant aluminum precision  
profile.  
Ball screw drive The ball screw drive converts a rotary movement into a linear move-  
ment. It consists of a ball screw, a ball nut with the ball recirculating el-  
ements and the bearing balls. A ball screw drive has a very high  
efficiency. It allows for high-precision, stiff feed movements and gener-  
ates high feed forces at high positioning accuracy and repeatability.  
Ball screw pitch The pitch of the ball screw shaft relates to the distance covered by the  
carriage per revolution of the ball screw. The greater the pitch the higher  
the maximum velocity.  
The following applies to the ball screw pitch:  
High pitch requires high driving torque  
High pitch results in high velocity  
High pitch causes high inaccuracy  
High pitch implies little self-locking  
Breakaway torque The breakaway torque describes the driving torque required to over-  
come the static friction and that initiates the transition to sliding friction.  
Buckling load Buckling is the loss of stability of the spindles when the max. permissible  
feed forces whose line of application is along the spindle axis are ex-  
ceeded. Exceeding the buckling load is expressed by a quickly increas-  
ing change in the shape of the spindle with a deviation to the side.  
Cantilever axis In the case of a cantilever axis, the carriage is stationary while the axis  
body moves. Portal axes work the other way round.  
Critical speed of the ball screw If the critical speed of the ball screw is exceeded, deflection of the ball  
screw and resonance will occur. This will seriously affect the service life  
of the ball screw drive. Ball screw supports are installed in longer ball  
screw axes to increase the critical screw speed and thus the perform-  
ance data.  
Drive element The drive element of the linear axis is a ball screw drive.  
Feed per revolution The feed per revolution is the distance the carriage covers per motor rev-  
olution.  
Linear guide The linear guide consists of the guide carriage and the profile rail.  
Load torque The permissible load torques are calculated based on the service life of  
the carriage guide. If the load torque exceeds the specified values, the  
service life of the axis will be reduced.  
Modulus of elasticity The modulus of elasticity is used to describe the tendency of a material  
to deform along an axis when opposing forces are applied along this  
axis; it is the ratio of tensile strain and tensile stress. The higher the  
value, the stiffer the material.  
Mounting position The linear axes can be installed in any desired position. However, all ex-  
ternal forces and torques must be within the ranges of permissible val-  
ues.

9 Glossary  
PAS4S  
Portal axis Generic term for driven axes and support axes. In the case of a portal  
axis, the axis body is stationary while the carriage moves. Cantilever  
axes work the other way round.  
Positioning accuracy Positioning accuracy is the tolerance between the specified position and  
actual position.  
Repeatability Repeatability is the accuracy with which it is possible to move to a pre-  
vious position again under the same conditions.  
Running accuracy Due to the manufacturing process, the extruded aluminium profiles have  
a certain tolerance in terms in straightness and twist. The tolerances are  
specified in EN 12020-2. To reach the desired running accuracy, the lin-  
ear axis must be mounted on a precision-machined surface.  
Self-locking The product is not self-locking. This means that motors with a holding  
brake, a separate holding brake or suitable weight compensation for the  
linear axis must be used, particularly so if axes are vertically mounted.  
Sensor Inductive proximity switches are used as sensors for limit switches or ref-  
erence switches. These switches are not a safety function.  
Service life The service life is the distance in kilometers before the first signs of ma-  
terial fatigue can be seen on the guides, the drive elements and the  
bearings. Service life specifications (kilometers covered) relate to the  
nominal values specified in the data sheet. If the nominal values are ex-  
ceeded, the service life decreases accordingly.  
Stiffness The stiffness shows information on the capacity of part that is to be po-  
sitioned to move and stop at the correct position, even under load vari-  
ations.  
Stroke reserve The stroke reserve is the distance between a limit switch and the me-  
chanical stop.  
Stroke Stroke is the maximum travel of the carriage between the switching  
points of the limit switches.  
Support axis A support axis has a linear guide, but no drive elements. A support axis  
carries loads that are applied asymmetrically to the carriage and im-  
proves the stability and service life of the system.
