– Motor defective.
– Short circuit in the cable.
– Output stage defective.
• Check motor, cable and motor controller.
Braking resistor is overloaded; too much braking energy which
cannot be dissipated quickly enough.
– Resistor capacity is incorrect?
– Resistor not connected correctly?
– Check design (application)
• Check the design of the braking resistor (positioning drives);
resistance value may be too great.
• Check the connection to the braking resistor (internal/external).
CMMS-ST only:
Encoder supply outside the permissible range (too high/too low).
• Test with another encoder.
• Test with another encoder cable.
• Test with another motor controller.
Only CMMS-AS/CMMD-AS:
Communication to serial angle encoders is disrupted (EnDat
encoders).
– Angle encoder connected?
– Angle encoder cable defective?
– Angle encoder defective?
• Check whether encoder signals are faulty?
• Test with another encoder.
• Check angle encoder cable.
For operation with long motor cables:
• Observe notes on EMC-compliant installation! Additional
anti-interference measures required from 15 m cable length.
