PLC setpoint fault

What does F00070 mean?

The drive is not receiving setpoint values from the PLC (Programmable Logic Controller) within the configured telegram off time. This indicates a communication issue or incorrect timing, causing the drive to lose its command reference and cease controlled operation, impacting automation sequences.

Complete Troubleshooting Guide

1. 1

   Review and adjust parameter p2040, which defines the monitoring time for PLC telegrams, to an appropriate value to prevent premature timeouts.

2. 2

   Acknowledge the fault in the drive's control interface.

3. 3

   If the fault persists after checking communication and p2040, consider replacing the inverter control unit, as it might indicate an internal communication hardware issue.
