[3] Emergency Stop Circuit
It is the example of circuit layout when an emergency switch of the teaching pendant is used to
the emergency stop circuit of the equipment.
Note 1: When the teaching pendant is not connected, S1 and S2 become short-circuited
inside the controller.
Note 2: When the motor power must be disconnected externally for safety category
compliance, apply a safety rated contactor between L and N.
Note 3: The rating for the emergency stop signal (EMG-) to turn ON/OFF at contact CR1 is
24V DC and 30mA.
Note 4: For CR1, select the one with coil current 0.1A or less.
