Output phase fault

What does F00023 mean?

One of the inverter's output phases to the motor is disconnected or open-circuited. This causes unbalanced current flow to the motor, leading to excessive motor heating, reduced torque, and potential damage to both the motor and the inverter if operation continues.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Measure the resistance or continuity of each motor phase winding to identify an open circuit.
