12. Error Diagnosis
Possible Cause Fault Remedy
- Input voltage too low or unstable
- Voltage losses due to incorrect cabling
- Motor is overloaded
- Input voltage too high
- Retarding torque too high
- Short-circuit or ground fault at the output
- Short-circuit of reference voltage of the resolver
- Check voltage suppply
- Check input line
- Check voltage suppply
- Connect braking resistor
- Determine exact cause and remove, next re-start
- Let motor cool down
- Check PTC - line
- Observe correct installation
- See also ambient conditions page E 7
- PTC - triggering
- PTC - line defective
- Heat dissipation too low
- Ambient temperature too high
- Discharge motor
- Reduce torque limit (Parameter CP.9)
- Remove external error and actuate RESET
- External error presetting
!
Only if parameter CP.15 = 0
!
- Fault correction only ex works!
- Check resolver line
- Fault correction only ex works!
- Fault correction only ex works!
- middle torque too large
- wrong cabling
- Reduce torque
- Control cabling from the motor to the encoder system
