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.
Torque on the Piston Rod
During commissioning and operation, the piston rod may only be operated
without torque.
If external torques occur, an external guide must be used.
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
Clean product
Requirement
–
Mounting of the drive system checked.
–
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.
–
Cylinder not mechanically overloaded 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 ≥ 0.25 mm away from the mechanical stops.
Steps
Purpose
Note
1. Check
travel
Determine the direc-
tion of travel of the
piston rod
–
Direction of movement of piston rod (clockwise spindle):
–
Retracting: rotate drive shaft clockwise.
–
Advancing: rotate drive shaft anti-clockwise.
–
The direction of movement of the piston rod for positive
and negative position values depends on the mounting
position of the motor on the cylinder (e.g. parallel or
axial kit).
–
Set a required reversal of direction of rotation via parame-
ters in the controller or controller.
2. Homing
Determination of
the reference point
and adjustment of
the dimensional ref-
erence system
–
during the initial
start-up proce-
dure
–
after replacement
of the motor
Permissible reference points:
–
towards reference switch:
Travel at reduced velocity
–
towards end position:
do not exceed maximum values

3. Test run
Checking the oper-
ating conditions
Check application requirements:
–
Piston rod runs through the complete travel cycle in the
specified time.
–
The piston rod stops travel when a limit switch or software
end position is reached.
After a successful test run, the drive system is ready for operation.

Operation
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.
Torque on the Piston Rod
During commissioning and operation, the piston rod may only be operated
without torque.
If external torques occur, an external guide must be used.
Lubrication run during operation
Observe the following lubrication travel intervals.
• With working stroke less than 2 x spindle pitch... P:
• Perform a lubrication run within 10 travel cycles with a minimum stroke of
≥ 2 x spindle pitch.

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
Cleaning
–
If the piston rod is dirty, clean it with a clean, soft and lint-free cloth without
cleaning agents and then apply the lubricant thinly to the piston rod.
–
Clean the other product components 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.
