5.6
(A) Application parameters
Purpose
To reduce the standby power
To restart after instantaneous
power failure
To decelerate the motor to a stop
at instantaneous power failure
5.6.1
Self power management
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.
