Maintenance, repairs and disposal
Read the general safety instructions before beginning work (see Chapter 2.7 "General safety
instructions").
Unless explicitly agreed otherwise for customer-specific motors, perform maintenance, repairs
and disposal according to the following sections.
7.1
Maintenance work
7.1.1 Cleaning
The motor may not come into contact with the solvents hexane and toluene, because they impair
the adhesion of the identification plates.
7.1.2 Checking the holding brake
The motor can be optionally equipped with a holding brake.
To ensure the permanent functioning of the holding brake, it has to be regularly applied and
checked.
- It is recommended that the holding brake is released and applied at least twice daily by
deactivating the controller.
- It is recommended that the holding torque M
4
of the brake is checked at least once a day.
Details can be found in chapter 6.1.5 "Holding brake".
7.1.3 Visual inspection
Perform a
monthly
visual inspection:
Check the motor and moving cables for damage.
Check whether the cables are completely labeled.
Remove any dust deposits.
ARS/TPM
+
:
Check the motor for leaking lubricant.
7.1.4 Checking for leakage (ARS only)
Check the motor every
three months
for leakages:
Check the gear output radial shaft seal for leakage.
Look for external emission of lubricant from the drive.
Open up the Ermeto screw connection in the adapter plate and check for any lubricant
leakage inside the adapter plate.
If a leak is detected, remove the lubricant and re-check the inside of the adapter plate after
brief operation. Lubricant discharge should stop after a short time.
In case lubricant is still leaking, shut down the motor and consult our Customer Service.
To prevent creating an explosive atmosphere by stirring up dust
deposits, any dust deposits on the motors must be removed by
regular cleaning.
When opening up the Ermeto coupling, dust could collect on the
adapter plate and catch fire during later operation.
Ensure that no explosive dust-air mixture is present and no dust can get
into the adapter plate before opening the Ermeto coupling or removing
the gearhead from the motor.
