13.13.4 Motor or machine generate vibrations
State Audible or tactile vibrations occur on the motor or on the machine.
Possible causes 1. Driven machine elements are insufficiently coupled or damaged.
2. Motor bearings are worn or defective. Available bearing lifetime or
grease lifetime has elapsed.
3. Motor mount has loosened.
4. Drive system is instable from a control point of view.
Countermeasures 1. Contact the machine manufacturer.
2. Contact the machine manufacturer.
3. Check the mechanical connection. Do not continue to use damaged
parts. Contact the machine manufacturer.
4. Check the parameterization of the drive system (motor and encoder da‐
ta). Comply with the instructions in the controller documentations.
13.13.5 Specified position is not reached
State The positioning command of the control unit is executed either not precisely
or not at all. No malfunction displayed by the controller or the control unit.
Possible causes 1. Wiring of encoder cable is incorrect or defective. Pin assignment (en‐
coder signals) in cable or plug may be interchanged.
2. Insufficient shielding of encoder cable against interference signals.
3. Incorrect parameterization of encoder data in controller.
4. Motor-machine element connection has loosened.
5. Encoder defective.
Countermeasures 1. Check wiring according to interconnection diagram of machine and
check cables for damage.
2. Check shielding; if necessary, increase effective contact surfaces of
shielding.
3. Correct the parameterization. Observe the commissioning log.
4. Check the mechanical connection. Do not continue to use damaged
parts. Contact the machine manufacturer.
5. The encoder has to be replaced. Contact the machine manufacturer.
