A082/A282
200/215/220/230/240
Selectable on 200 V class inverter models
380/400/415/440/460/480

gain
A084 50.～200.(%) See diagram below. (*2)
*1 Disabling the AVR function at motor deceleration increases the energy loss on the decelerated motor
and decreases the energy regenerated on the inverter, which results in a shorter deceleration time.
*2 Operate regardless of the A081/A281.
