V/F V/F V/F Magnetic flux Magnetic flux Magnetic flux
By turning ON the magnetic contactor (MC) on the input side before the motor is started and turning OFF the MC after the motor
is stopped, power is not supplied to the main circuit, reducing the standby power.

Self power management function disabled
Self power management function enabled (main circuit OFF at protective
function activation)
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.
