Faulty PAR1 Transfer

What does Pr1 mean?

An error occurred during the transfer of parameter set 1 (PAR1) via the operating module, indicating that PAR1 is defective or corrupted. This means the primary operating configuration of the drive is unreliable. The drive should not be enabled until this is resolved, as it may operate incorrectly or unsafely.

Complete Troubleshooting Guide

1. 1

   Repeat the data transfer for PAR1 from the operating module to the drive.

2. 2

   If the transfer fails again, load the factory default settings for PAR1 before attempting to enable the controller.

3. 3

   If the issue persists, consider replacing the operating module or troubleshooting the communication link.
