Emergency stop circuit when multiple controllers are linked
Internal drive-source cutoff specification (Connections when the entire system requires a level of safety conforming to safety category B)
Connect an emergency-stop status relay contact for each controller. Make sure to install a surge-absorbing element for the external relay.
S1, S2 contact specification: 30 VDC/0.5 A
Caution: When the teaching pendant is disconnected, an emergency stop is actuated momentarily. The emergency stop will be cancelled
immediately thereafter, but the actuator and other equipment that are operating when the teaching pendant is disconnected will stop.
Therefore, do not disconnect the teaching pendant when an actuator or any other equipment is operating.
Also pay attention to the design of the emergency stop circuit that includes the emergency stop switch on the teaching pendant.
