4.2.18 Automatic restart after instantaneous power failure
(Pr. 57, Pr. 58)
Pr. 57 "restart coasting time"
Pr. 58 "restart cushion time"
! You can restart the inverter without stopping the motor (with the motor coasting)
when power is restored after an instantaneous power failure.

Waiting time for inverter-triggered restart after power is restored
from an instantaneous power failure. (Set this time between 0.1s
and 5s according to the inertia moment (J) and torque of the
load.)
9999 No restart
Normally the inverter may be run with the factory settings. These
values are adjustable to the load (inertia moment, torque).
