Low Voltage (Undervoltage) Trip

What does 32 mean?

This fault indicates that the drive has detected an undervoltage condition or power dip, which it could not ride through. Depending on parameter 501 settings (Coast Stop or Controlled Stop), the drive will either coast to a stop or decelerate the motor before faulting. This protects the drive and motor from operation with insufficient input power.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review parameter 501 settings to understand the drive's behavior during undervoltage conditions. Adjust if necessary for ride-through capabilities.

2. 4

   If the power supply is verified as stable, consult the factory as there may be an internal issue with the drive's voltage sensing circuitry.
