 Operation in combination with the self power management function for
the separated converter type
• When the self power management function is used with the separated converter type, the input signal operations are as
follows.

OFF
ON
OFF
*1 When Pr.138 = "0 (electronic bypass invalid at a fault)", MC2 is OFF. When Pr.138 = "1 (electronic bypass valid at a fault)", MC2 is ON.
*2 The self power management operation is followed.
*3 MC operation is as shown below.

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.

Set a time period that is a little longer than the time period from the ON
0 to 100 s
signal input to the actual pick-up operation of MC1 (0.3 to 0.5 s).
Set the delay time until the main circuit power supply is turned OFF after
1 to 3600 s
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
