DOK-MOTOR*-MBS-H******-PR02-EN-P
Motor or machine generates vibrations
Audible or tactile vibrations occur on the motor or on the machine.
1. Driven machine elements are insufficiently coupled or damaged.
2. Motor bearings worn or defective. Available bearing lifetime or
grease lifetime elapsed.
3. Motor mount loose.
4. Drive system control circuit is instable from a control point of view.
1. Contact the machine manufacturer.
2. Check the mechanical connection. Do not continue to use damaged
parts. Contact the machine manufacturer.
3. Check the parameters of the drive system (motor and encoder data).
Observe the troubleshooting notes in the documentation for the drive
controller.
Specified position is not attained
The positioning command of the control is not precisely executed – or
not at all. No malfunction display on the drive controller or the control.
1. Wiring of encoder cable is incorrect or defective. Pin assignment
(encoder signals) in cable or plug may be switched.
2. Insufficient shielding of encoder cable against interference.
3. Incorrect encoder parameters set in drive controller.
4. Motor-machine connection loose.
5. Encoder defective.
1. Check the wiring according to the connection plan and check the
state of cables for damage.
2. Check the shielding; if necessary, increase the effective contact
surfaces of the shielding.
3. Correct the parameters. Observe the start-up report for original
values.
4. Check the mechanical connection. Do not continue to use damaged
parts. Contact the machine manufacturer.
5. Change of encoder necessary. Contact the machine manufacturer.
