Mitsumi electronic 55K Parameter Factory Setting Remarks, 9999 1 to No restart, 164, 165 120%

PARAMETERS

4.2.24Automatic restart after instantaneous power failure (Pr. 57, Pr. 58, Pr. 162 to Pr. 165)

Pr. 57 "restart coasting time

Pr. 58 "restart cushion time

Pr.162 "Automatic restart after instantaneous power failure selection" Pr.163 "First cushion time for restart"

Pr.164 "First cushion voltage for restart"

Pr.165 "Restart stall prevention operation level"

#You can restart the inverter without stopping the motor (with the motor coasting) when the commercial power supply is switched to the inverter operation or when the power is restored after an instantaneous power failure. (When restart operation is set to be enabled, an automatic restart after instantaneous power failure is made without the E.UVT (undervoltage protection) or E.IPF (instantaneous power failure protection) alarm output signal being output at occurrence of an instantaneous power failure.)
