PARAMETERS
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.
<Setting>
Refer to the following table and set the parameters:
*The output shut off timing differs according to the load condition.

001 to 002 0.5 s coasting time
Generally use this
setting.
003 to 010 3.0 s coasting time
0.1 to 5 s
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
58 0 to 60 s
Normally the inverter may be run with the factory settings. These
values are adjustable to the load (inertia moment, torque).
