 Fault output after deceleration to stop (Pr.573 = "3")
• When the analog current input becomes 2 mA or lower, the inverter output decelerates the motor to a stop, and then the
protective function E.LCI (4 mA input fault) is activated and the output is shut off.
• When the analog current input is restored during the deceleration, the motor is accelerated again and operates according
to the current input.
• The following is the operation example during PID control (reverse action) operation.
