..... Output current value is used to

perform integration processing.

..... Perform integration processing

using output current of 0A.

..... Electronic thermal relay function

is not activated (cumulative value clear)

CAUTION

Set this parameter correctly according to the motor used. Incorrect setting may cause the motor to overheat and burn.
