Commissioning

7.1

Safety

WARNING

Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
• Perform commissioning with low dynamic response.

7.2

Performing commissioning

Block-shaped acceleration profiles (without jerk limitation) can have the following
effects:
• High mechanical loads on the lead screw due to high force peaks.
• Overshooting effects during positioning.
• Rise of the entire system.
Recommendation: reduce high force peaks in the acceleration and deceleration
phases by using the jerk limitation.

When the motor is removed, the motor encoder loses its absolute reference to the
reference mark (e.g. by turning the motor drive shaft).
• Carry out a homing run after every motor mounting in order to establish the

absolute reference between the motor encoder and the reference mark.

Running noises during operation
Identically constructed axes can generate different running noises depending on
the parameterisation, mode of operation, type of mounting, installation environ-
ment and components.

For use with reduced particle emission

 9.3 Cleaning.

Requirement

Mounting of the drive system checked.

The protective cover of the cover strip is removed.

Installation and wiring of the motor checked.

No foreign objects in the movement space of the drive system.

Maximum permissible feed force and drive torque not exceeded as a function
of acceleration, deceleration (e.g. stop function, quick stop), velocity, moving
mass and mounting position.

No mechanical overload of the axis and dynamic setpoint deviation not
exceeded (e.g. overrunning the end position) due to force and torque peaks
or overshoot effects.
Limit overloads and overruns by jerk limitation, lower acceleration and deceler-
ation setpoints or optimised controller settings.

Control and homing travel at reduced velocity, acceleration and deceleration
setpoint values.

No test run to mechanical end stops.

Software end positions do not lie within the effective range of the mechanical
stops.

Steps

Purpose

Note

1. Check travel

Determining the direction of
travel of the slide

The direction of movement of the slide

for positive and negative position values
depends on the mounting position of the
motor on the axis.

Set a required reversal of direction of rota-

tion via parameters in the controller or
controller.

2. Homing

Determination of the reference
point and adjustment of the
dimensional reference system

during the initial start-up pro-

cedure

after replacement of the motor

Permissible reference points:

towards reference switch.

data.

3. Test run

Checking the operating condi-
tions

Check application requirements:

Slide travels through the complete travel

cycle in the specified time.

Slide stops moving when a limit switch is

reached.

After a successful test run, the drive system is ready for operation.

Maintenance

9.1

Safety

WARNING

Unexpected movement of components.
Injury due to impacts or crushing.
• Before working on the product, switch off the control and secure it to prevent it

from being switched back on accidentally.

9.2

Checking axis elements

Checking reversing backlash

Check the reversing backlash of the slide at every maintenance interval
(e.g. lubrication interval).
If the maximum permissible reversing backlash is exceeded, the axis should
be replaced.

Cleaning

Clean the product with a clean, soft cloth and non-abrasive cleaning agents.

For use with reduced particle emission:

Remove abrasion and contamination from the product on the following
schedule:

Prior to initial commissioning.

Regularly during operation.

9.4

Lubrication

The axis is lubricated for life.
Additional lubrication of the axis is not necessary.
