Cause : 4 mA input fault comes when the inverter output is shut off when the analog input current is 2 mA or less for the time set in Pr.778 4 mA input check filter. This function is available when Pr.573 4 mA input check selection = "2 or 3". This protective function is not available in the initial status.
- Check for a break in the wiring for the analog current input.
- Check that the Pr.778 setting is not too short.
- Check the wiring for the analog current input.
