Control Panel setpoint fault

What does F00073 mean?

The drive is not receiving setpoint values from the Control Panel within the specified telegram off time. This indicates a communication issue or incorrect timing between the control panel and the drive, causing a loss of command signals and controlled operation, thus preventing manual control.

Complete Troubleshooting Guide

1. 1

   Review and adjust parameter p3984, which defines the monitoring time for control panel telegrams, to an appropriate value.

2. 2

   Acknowledge the fault in the drive's control interface.

3. 3

   If the fault persists after checking communication and p3984, consider replacing the inverter control unit due to a potential hardware issue.
