State Vibrations can be heard or felt at the motor.
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 come loose.
4. Drive system is instable from a control point of view.
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.
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.
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.
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.
The products are manufactured in energy- and resource-optimized produc‐
tion processes which allow re-using and recycling the resulting waste. We
regularly try to replace pollutant-loaded raw materials and supplies by more
environment-friendly alternatives.
Our products do not contain any hazardous substances which may be re‐
ces
leased in case of appropriate use. Normally, our products will not have any
negative influences on the environment.
