(T) Multi-Function Input Terminal Parameters
Fault output (Pr. 573 = "2")
● When the analog current input becomes 2 mA or lower, 4 mA input fault (E.LCI) will be activated
and the output is shut off.
● PID control (reverse action)
Output frequency

Fault output after deceleration to stop (Pr. 573 = "3")
● 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.
● PID control (reverse action)
