Mitsubishi FR-A500 Series - Automatic Restart after Instantaneous Power Failure (Pr. 57, Pr. 58, Pr. 162 to Pr. 165)

PARAMETERS
89
4.2.23 Automatic 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 automatic restart operation is set to be enabled, UVT and IPF among the alarm
output signals will not be output at occurrence of an instantaneous power failure.)
