Emergency Stop Circuit in the RC7M Controller (Standard type of controller)
The internal relay receives the External Emergency Stop input signal and the
emergency stop input from the teach pendant to output this signal. When the power
is turned OFF, the controller is in the emergency stop state.
The two contacts on the emergency stop button (4b) on the teach pendant are
connected. This signal will be issued independent of the ON/OFF state of the
controller power.
