(T) Multi-Function Input Terminal Parameters

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)
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)
• The analog input current is restored during deceleration under PID control (reverse action)
