Restart cushion time (Pr. 58)
Cushion time is the length of time when the voltage appropriate to the voltage at the detected motor
speed (output frequency prior to instantaneous power failure when Pr. 162 = "1" or "11") from 0 V.
Normally the initial value need not be changed for operation, but adjust it according to the magni-
tude of the moment of inertia (J) of the load or torque.
Automatic restart operation adjustment (Pr. 165, Pr. 611)
Using Pr. 165, you can set the stall prevention operation level at a restart.
Using Pr. 611, you can set the acceleration time until the set frequency (Pr. 20) is reached after auto-
matic restart operation is performed besides the normal acceleration time.

NOTE
If the setting of Pr. 21 "Acceleration/deceleration time increments" is changed, the setting incre-
ments of Pr. 611 does not change.
