paragraph 6.6.1.
Sub-code
Condition: No alarm present
Condition: DC link overvoltage alarm due to energy recovered from the motor.
The voltage arriving at the drive power section is too high compared to the maximum threshold
relating to the PAR 560 Mains voltage parameter setting.
Solution:
- Extend the deceleration ramp.
- Use a braking resistor between terminals BR1 and BR2 to dissipate the recovered energy
- Use the VDC Control function
Condition: DC link undervoltage alarm.
The voltage arriving at the drive power section is too low compared to the minimum threshold
relating to the 560 Mains voltage parameter setting due to:.
- the mains voltage being too low or overextended voltage drops.
- poor cable connections (e.g. loose contactor terminals, inductance, filter, etc. ).
Solution: Check the connections.
Condition: Ground short circuit alarm
Solution:
- Check drive and motor wiring.
- Check that the motor is not grounded.
Condition: Instantaneous overcurrent protection intervention alarm.
This may be due to the incorrect setting of current regulator parameters or a short circuit
between phases or ground fault on the drive output.
Solution:
- Check the current regulator parameters
- Check wiring towards the motor
Condition: Instantaneous overcurrent in the IGBT bridge alarm.
Solution: Switch the drive off and then switch it on again.
If the alarm persists, contact the technical service centre.
Condition: The number of attempted automatic restarts after the Undervoltage alarm has
exceeded the set PAR 4650 UVRep attempts value in the PAR 4652 UVRep delay time.
Solution: Too many Undervoltage alarms.
Adopt the proposed solutions for the Undervoltage alarm.
Condition: 2 attempted automatic restarts after the Overcurrent alarm within 30 seconds. If
more than 30 seconds pass after the Overcurrent alarm was generated, the attempt counter is
reset.
Solution: Too many Overcurrent alarms. Adopt the proposed solutions for the Overcurrent
alarm.
Condition: 2 attempted at automatic restarts after the Desaturation alarm within 30 seconds.
If more than 30 seconds pass after the Desaturation alarm was generated, the attempt counter
is reset.
Solution: Too many Desaturation alarms.
Adopt the proposed solutions for the Desaturation alarm.
