Analogue input I in < 4mA

What does 50 mean?

The analogue input configured for a 4-20 mA current loop is receiving a current signal below 4mA. This typically indicates a break or loose connection in the control cable, or a failure of the signal source device. Loss of the analogue signal means the drive cannot receive its intended reference or feedback, leading to incorrect control.

1. 3

   Check the impedance and integrity of the entire current loop circuitry for proper operation.
