50
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.
Complete Troubleshooting Guide
- 1
Inspect the analogue input control cable for breaks, damage, or loose connections at both ends.
- 2
Verify the functionality and output of the signal source device (e.g., sensor, transducer) supplying the current.
- 3
Check the impedance and integrity of the entire current loop circuitry for proper operation.
