Automatic Restart After Instantaneous Power Failure (Pr. 57, Pr. 58) - Mitsubishi FR-E 500 Instruction Manual

4.2.22 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 0.1 s
0.1 to 5 s
and 5 s 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
0 to 60 s
values are adjustable to the load (inertia moment, torque).
