IPOS control word invalid

What does 77 mean?

In IPOS operating mode, an attempt was made by an external controller to set an invalid automatic mode via the control word, or parameter P916 is set incorrectly. This leads to a 'no response' behavior, preventing unintended or unsafe operation.

Complete Troubleshooting Guide

1. 1

   Check the serial connection to the external controller for integrity and proper data transmission.

2. 2

   Verify the write values being sent by the external controller to ensure they are valid for IPOS automatic modes.

3. 3

   Set the correct value for parameter P916 according to the desired functionality and IPOS control requirements.
