Acceleration stop/Deceleration stop
–
The acceleration stop and deceleration stop
frequency setting allows you to make the inverter wait, upon starting the motor or upon
decelerating the motor, until the motor slip becomes less when the motor load causes a
large moment of inertia. Use this function if the inverter trips because of overcurrent
when starting or decelerating the motor. This function operates with every acceleration
and deceleration pattern, regardless the acceleration and deceleration curve selection
(

and

). Instead of setting

,

,

and

, acceleration and
deceleration can be held by intelligent input configured as "

:HLD".
