3.8.2 Cutting off the Motor Drive Power Supply
If the safety category of the entire equipment requires motor drive power cut off, connect the EMG relay contact
between the MPI terminal and MPO terminal.
In addition, connect 24V of the controller power supply to the EMG terminal.
(Note) Please pay sufficient attention that the EMG switch of the teaching pendant leads to motor drive
signal shutdown and not motor drive power cutoff.
