Cause : Output phase loss comes when the drive has detected a loss of one or more of the output phases to the motor.

"E13.00" fault in inovance MD800 drive indicate "Output phase loss". This means the drive senses that one or more of the motor output phases are not functioning correctly, which can lead to erratic motor behavior or damage.

Possible Causes:

1. Loose or Disconnected Wiring: Loose or disconnected wires between the drive and the motor can cause a phase loss.
2. Faulty Motor Connections: Damaged or faulty connections at the motor terminals can result in phase loss.
3. Internal Drive Faults: Issues within the drive, such as a malfunctioning output stage or power module, can lead to phase loss detection.
4. Motor Issues: Internal faults or short circuits within the motor windings can cause the drive to detect a phase loss.
5. Electrical Interference: Electrical noise or interference in the system could affect the drive’s ability to correctly monitor the output phases.

Troubleshooting Steps:

1. Check Wiring and Connections:

   • Inspect Wiring: Examine all wiring between the drive and the motor for loose connections, damage, or disconnections. Ensure that all connections are secure and properly terminated.
   • Verify Motor Terminals: Check the motor terminals to ensure that all phase connections are secure and correctly made.

2. Examine Motor and Drive:

   • Test Motor: Use a multimeter or insulation resistance tester to check for any faults in the motor windings, such as short circuits or open circuits.
   • Inspect Drive: Look for any visible signs of damage or malfunction in the drive’s output stage or power modules.

3. Check for Electrical Interference:

   • Evaluate Electrical Noise: Assess the system for any sources of electrical noise or interference that could affect phase monitoring. Consider using shielding or filtering if necessary.
   • Review Grounding: Ensure that both the drive and motor are properly grounded to reduce electrical noise and interference.

4. Verify Drive Settings:

   • Check Output Phase Settings: Confirm that the drive’s settings related to output phases are correctly configured and aligned with the motor’s specifications.
   • Adjust Parameters if Needed: If applicable, adjust the drive’s parameters related to phase monitoring or fault detection.

5. Perform Diagnostic Tests:

   • Use Drive Diagnostics: Utilize the drive’s built-in diagnostic tools to test for and identify any internal faults related to output phase monitoring.
   • Run Self-Test: If available, run a self-test or calibration procedure on the drive to ensure its output stage is functioning correctly.
