 Fault output after deceleration to stop (Pr.573 = "3, 13, or 23")
• When the analog current input becomes 2 mA or lower, 4 mA input fault (E.LCI) will be activated after the deceleration stop
and the output is shut off.
• When the analog current input is restored during the deceleration, it will accelerate again and operate according to the
current input.
• The following is the operation example during PID control (reverse action) operation.
Output frequency
20 mA
