PIF

Phase Inversion

Schneider Electric · Altistart 22 Soft Starter

What does PIF mean?

The sequence of the incoming line phases (L1, L2, L3) does not conform to the expected sequence configured by the 'PHr' parameter in the soft starter. This can cause the motor to rotate in the incorrect direction or prevent it from starting.

Complete Troubleshooting Guide

  1. 1

    Physically invert the connection of two of the incoming line phases (e.g., L1 and L2) to correct the phase sequence.

  2. 2

    Alternatively, if the phase sequence is not critical for your application or is managed by external controls, set the 'PHr' parameter to 'oFF' in the 'PrO' menu.
