IPM OverCurrent

What does 35 mean?

The current magnitude has exceeded the trip level set by P1640 [IPM Max Cur], as detected by the Intelligent Power Module (IPM). This fault protects the drive from severe damage due to excessive current. If persistent, it strongly indicates an overload, a short circuit condition in the motor or wiring, or an incorrect setting of P1640.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check motor and power cabling for insulation damage or phase-to-phase/phase-to-ground short circuits.

2. 4

   If no external cause is found, suspect a potential internal drive hardware failure.
