NOTE
• When the setting is changed to the continuous operation (Pr.573 = "1 or 4") after the input current loss, the frequency before
loss is regarded as 0 Hz.
 Fault output (Pr.573 = "2")
• When the analog current input becomes 2 mA or lower, the protective function E.LCI (4 mA input fault) is activated and the
output is shut off.
• The following is the operation example during PID control (reverse action) operation.

 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.
