Defective Parameter Set 1

What does Pr1 mean?

Parameter set 1 within the controller has become defective, likely due to an interrupted or faulty transfer from the keypad. This indicates a corruption in a specific configuration set, which can prevent proper drive operation when that set is active. Operating with corrupted parameters can lead to unpredictable behavior.

Complete Troubleshooting Guide

1. 1

   Repeat the parameter data transfer process specifically for parameter set 1 from the keypad or PC, ensuring it completes without interruption.

2. 2

   If the issue persists, try loading the factory default Lenze parameter settings for set 1.

3. 3

   Ensure the keypad or PC connection is stable throughout the transfer process.
