What does A01654 mean?

The PROFIsafe configuration in the higher-level control differs from that in the drive. This inconsistency can lead to communication errors or safety function issues, preventing reliable and safe operation. Specific alarm values (r2124=1 or r2124=2) provide more detail.

Complete Troubleshooting Guide

  1. 1

    If r2124 = 1: Remove PROFIsafe configuring in the higher-level F control or enable PROFIsafe in the drive.

  2. 2

    If r2124 = 2: Configure the appropriate PROFIsafe telegram in the higher-level F control.
