4mA supervision

What does F50 mean?

The current at an analog input has dropped below the 4mA supervision limit. This typically indicates a failure in the signal source, a broken control cable, or a loose connection within the current loop circuitry. This means the drive is not receiving expected sensor feedback.

Complete Troubleshooting Guide

1. 1

   Thoroughly inspect the entire current loop circuitry, including the signal source, wiring, and connections at both the drive and the sensor.
