8.8 Safety plug
This signal is used to turn OFF the servo power if the door of the protective device is
opened. Connect to the interlock signal from the safety plug on the safeguarding door. If the
interlock signal is input, the servo voltage is turned ON, as long as the signal is ON. The
servo power cannot be turned ON. Note that these signals are disabled in teach mode.
CAUTION!
Injuries and machine damages caused by short-circuit
Jumpers are installed at the factory. If the jumpers are not removed, the external emergency
stop will not work even with incoming signal.
Be sure to remove the jumper before using.
