What causes output phase loss on Invertek Drives DC drive?
- MManuel GonzalezSep 12, 2025
One of the motor output phases is not connected to the drive.
What causes output phase loss on Invertek Drives DC drive?
One of the motor output phases is not connected to the drive.
What does encoder feedback fault mean on Invertek Drives DC drive?
Encoder communication /data loss.
How do I troubleshoot a CAN Open comms trip on my Invertek Drives DC drive?
Check that the network master / PLC is still operating. Check the connection cables. Increase the value of P5?06 to a suitable level.
What to do if measured motor stator resistance varies between phases on Invertek Drives DC drive?
Ensure the motor is correctly connected and free from faults. Check the windings for correct resistance and balance.
What to do if measured motor inductance is too low on Invertek Drives DC drive?
Ensure the motor is correctly connected and free from faults.
What to do if Invertek Drives DC drive shows instantaneous over current and excess load?
If the fault occurs on drive enable, inspect the motor and its connection cable for phase-to-phase and phase-to-earth short circuits. Also, verify the load for any mechanical jams, blockages, or stalled conditions. Ensure the motor nameplate parameters are correctly entered (P1?07, P1?08, P1?09). If operating in Vector mode (P4?01 – 0 or 1), check the motor power factor in P4?05 and ensure an autotune has been successfully completed. Try reducing the Boost voltage setting in P1?11 and increasing the ramp-up time in P1?03. If the motor has a holding brake, confirm it's correctly connected, controlled, and releasing properly. If the fault occurs when running in Vector mode, reduce the speed loop gain in P4?03.
What to do if measured motor inductance is too large on Invertek Drives DC drive?
Ensure the motor is correctly connected and free from faults. Check that the power rating corresponds to the power rating of the connected drive.
What to do if measured motor parameters are not convergent on Invertek Drives DC drive?
Ensure the motor is correctly connected and free from faults. Check that the power rating corresponds to the power rating of the connected drive.
How to fix Modbus comms fault on Invertek Drives DC drive?
Check that the network master / PLC is still operating. Inspect the connection cables. Increase the value of P5?05 to a suitable level.
How to resolve brake channel over current on Invertek Drives DC drive?
Ensure the connected brake resistor is above the minimum permissible level for the drive. Check the brake resistor and wiring for possible short circuits.
