Cause: Output phase to phase short-circuit fault comes when internal motor failure where two windings are shorted together or faulty motor cable.

E24.00 fault in inovance IS580 drive indicates Output Phase-to-Phase Short-Circuit Fault. This means the drive has detected a short circuit between two of its output phases (U, V, W), either inside the motor, cable, or even inside the drive's output stage (IGBTs).

• Check motor & motor cable.
• Remove motor cable & check same fault comes.
• Ensure terminals aren’t shorted by stray copper strands, water, or loose lugs.
• Check drive IGBT using multimeter.
