1 Introduction

1.1 Overview of product properties

The ball screw axes are based on specially developed and particularly torsion-resistant aluminum profiles. They excel with the their ability to position heavy loads at changing torques with high feed forces and high accuracy.

1.1.1 Product family

The linear axes product family consists of the following sizes:
• PAS42Sx (axis body cross section 60x60 mm)
• PAS43Sx (axis body cross section 80x80 mm)
• PAS44Sx (axis body cross section 110x110 mm)
The sizes differ in terms of outer dimensions, drive data, payload capac­ities and maximum stroke.

1.1.2 Features and options of the linear axis

The linear axis excels with the following features and options:
• High positioning accuracy even at great ballscrew lengths due to several moving screw supports
• Simple integration into systems and machines due to axis bodies with slots
• Stroke length available precise to the millimeter
• Mounting thread with counterbores for locating dowels at the car­riage for reproducible mounting of the payload
• Grease nipples at the side of the carriage for external lubrication
• Distribution of the payload to up to 3 carriages
• Optional cover strip
• Motor mounting via compact coupling system
• Sensors adjustable in T slots

1.1.3 Features of the linear guide

Recirculating ball bearing guide • High acceleration
• High load capacity
• High accuracy
• Suitable for high torques
• Optimum absorption of forces by the axis body

2.3 Basic information

@ WARNING
GREAT MASS OR FALLING PARTS
• Consider the mass of the axis when mounting it. It may be neces­sary 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. Consid­eration must be given to the implication of unanticipated transmis­sion delays or failures of the link.
• Observe the accident prevention regulations and local safety guidelines.
• Each implementation of the product must be individually and thor­oughly tested for proper operation before being placed into serv­ice.
Failure to follow these instructions can result in death or serious injury.

@ WARNING
GREAT MASS OR FALLING PARTS
• Consider the mass of the axis when mounting it. It may be neces­sary 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 hold­ing 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 equip­ment 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 instal­lation site. Do not remove the packaging until the product is at the instal­lation site.
The linear axis may only be lifted at points A and B (see figure). The dis­tance 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
B
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.

PAS 4•S 4 Installation

4.2 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 appropri­ate 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 fas­tening).
A selection of suitable clamping claws and slot nuts can be found in chapter 7 "Accessories and spare parts".
Note the following:
• When using motors with a cross section greater than the cross sec­tion 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 sur­face.
• If the lateral slots are used for mounting, the sensor cable cannot be completely routed in the slots.

The greater the load or the demands on the running accuracy, the shorter the distance between the slot nuts or the clamping claws must be.
48 Portal axes with ball screw drive
Page 49
PAS 4•S 4 Installation
Alignment for running accuracy Due to the manufacturing process of the extruded profiles, a linear axis
has a certain tolerance in terms in straightness and twist. The deviations are generally well within the specifications of EN 12020-2 in the case of the product.
Perform the following lateral alignment procedure for running accuracy.
쮿 The mounting surface must be machined smooth and flat.
왘 First, slightly tighten the screws of the slot nuts or the clamping
claws.
왘 Provide a reference plane alongside the linear axis.
왘 Place a dial gauge onto the carriage.
왘 Move the carriage and record the deviation with reference to the ref-
erence plane over the entire stroke.
왘 Correct the deviations by lateral alignment of the linear axis and by
tightening the screws appropriately. Observe the standard tighten­ing torques 47.

4.2.3 Mounting the contact plate

A contact plate must be mounted to the carriage for the inductive sen­sors. Fastening threads are located at both sides of the carriage.
Unless otherwise specified, the standard tightening torques indicated on page 47 apply.
Before mounting See chapter 7 "Accessories and spare parts", subchapter 7.5 "Sensors
and additional parts" for suitable contact plates.
You need a set of Allen keys.
왘 Clean all parts you will use.
왘 Check all parts for damage; repair damages.
Procedure
왘 For mounting, select the side of the carriage that will be easily
accessible for service.
왘 Screw the contact plate to the carriage with M4 screws.
왘 Align the contact plate in parallel with the carriage so as to have the
same switching distance on both sides.

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 protec­tion 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.
왘 Clean all parts you will use.
왘 Check all parts for damage; repair damages.
왘 Check the sensor for correct type and function.
왘 Verify that your controller and your interface are suitable for the sen-
sor.
왘 See the dimensional drawings in chapter 3 "Technical Data" for
information on the sensor position..
Procedure
2 M3 hex socket screw with hex nuts are located at the sensor.
• Screw (1) is used to fasten the sensor holder in the slot.
1
• Screw (2) is used to fasten the sensor in the sensor holder.
3
In addition, the sensor holder features cams (3) at both sides to keep the
2
1
sensor from turning in the T slot.
왘 Slide each nut into the T slot at the cutout.
왘 Place the the sensor holder with the two screws into position. Leave
the two screws loose at first.
왘 Slide the sensor holder to the desired position and tighten screw (1)
with a torque of 0.3 Nm.
50 Portal axes with ball screw drive
Page 51
PAS 4•S 4 Installation
Since the sensor operates inductively, the switching surface must have a specific distance from the contact plate. This so-called "switching dis­tance" amounts to 0.5 ±0.1 mm.
왘 Move the carriage until the contact plate is above the sensor holder.
왘 Slide the sensor through the sensor holder opening until the switch-
2
1
ing distance has been reached.
Measure the distance using a feeler gauge.
왘 Tighten screw (2).
왘 Finally, check the switching distance with the feeler gauge.
The slot (1) can hold up to 3 sensor cables. Suitable slot covers are available on request.
왘 Route the sensor cable in the slot.

4.2.5 Mounting the motor or the gearbox

The motor or the gearbox are coupled by means of a preloaded elatomer coupling.
The motor or the gearbox can be mounted in different arrangements (turned in increments of 4 x 90°).
Unless otherwise specified, the standard tightening torques indicated on page 47 apply.

Mounting the elastomer coupling The elastomer coupling has two clamping hubs which may have differ-
ent holes.
왘 Slide the matching clamping hub onto the shaft extension of the lin-
ear axis all the way to the stop.
왘 Tighten the clamping screw at the clamping hub with the tightening
torque specified in Table 4.2.
왘 Fit the elastomer spider onto the clamping hub.
Slightly greasing the ring gear or the hub facilitates the fitting proc­ess. Use only mineral oil based lubricants without additives or sili­con based lubricants.
NOTE: If the elastomer spider can be fitted too easily (without preloading), it must be replaced.
왘 Mount the coupling housing with the 4 screws. Verify that the cou-
pling housing has even contact.

@ 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 neces­sary 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.
If you cannot resolve an error yourself please contact your sales office. Have the following details available:
• Nameplate (type, identification number, serial number, DOM, ...)

8.2 Maintenance

The maintenance intervals for cleaning and lubrication must be adhered to.
왘 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 con­taminants 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.
왘 Do not use compressed air for cleaning.
왘 Remove large particles and dirt from the surface at regular inter-
vals.
왘 The anodized surface only has a limited resistance to alkaline
cleaning agents. Therefore, use only neutral cleaning agents for cleaning.
왘 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.
왘 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. There­fore, 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:
Linear guide • 5000 km operational performance
Size Lubricant Relubrication volume Strokes

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 el­ements and the bearing balls. A ball screw drive has a very high efficiency. It allows for high-precision, stiff feed movements and gener­ates 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 ex­ceeded. Exceeding the buckling load is expressed by a quickly increas­ing 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 perform­ance 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 val­ues.

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 lin­ear 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 ex­ceeded, 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 vari­ations.
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 im­proves the stability and service life of the system.
