Automatic Restart After Instantaneous Power Failure (Pr. 57, Pr. 58, Pr. 162, Pr. 165, Pr. 611) - Mitsubishi Electric FR-A500 Instruction Manual

4.2.23 Automatic restart after instantaneous power failure
(Pr. 57, Pr. 58, Pr. 162, Pr. 165, Pr. 611)
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"
Pr. 611 "restart acceleration time"
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 (under voltage protection) or E.IPF (instantaneous power failure
protection) alarm output signal being output at occurrence of an instantaneous power failure.)
