Self power management function enabled (main circuit OFF
at protective function activation due to a circuit failure)
Set a time period that is a little longer than the time period
from the ON signal input to the actual pick-up operation of
MC1 (0.3 to 0.5 s).
Set the waiting time until the main circuit power supply is
turned OFF after the motor is stopped.
The main circuit power supply is turned OFF only when the
protective function selected by Pr.248 is activated.
Power supply to the inverter: AC (terminals R, S, and T)
When power is supplied only to the control circuit, and then
switched to be supplied to both the control and main circuits,
inverter reset is not performed.
