2-11 Wiring of an external emergency stop

2-11-1 External emergency stop setting

Besides the emergency stop input from the NC communication cable (CN1A, CN1B), double-protection
when an emergency stop occurs can be provided by directly inputting an external emergency stop to the
CN23 connector on the power supply unit. Even if the emergency stop is not input from CNC for some
reason, the contactors will be shut off by the external emergency stop input from CN23 connector on the
power supply unit.
