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.
