NOTE The internal circuits are shown below. While it is possible to switch either the AC or DC side of
the brake power supply, it is normally safer to switch the AC side. If the DC side is to be
switched, install a surge suppressor near the brake coil to prevent the surge voltages due to
switching the DC side damaging the brake coil. Brake operation time delay occurs during
brake power supply ON/OFF operation. Set output timing of servo OFF operation (motor out-
put stop), referring to “3.4.4 Using Holding Brake.” Especially, if the AC side of the brake pow-
er supply is to be switched, brake operation time is extended.
