4.4 Safety Door and Enable Input
To connect the safety door switch, etc. from external equipment, input the signals
from the SAFE connector (between 13 and 14 and between 15 and 16) on the
controller front panel. When either of these signals is open, emergency stop status
cannot be canceled as with the emergency stop switch. To restore the system from
the emergency stop status, place all connected safety door switches in close status.
The controller enters normal status.
The operation of this signal from the teach pendant varies depending on the mode
selected by means of the master mode switch on the controller front panel.
In TEACH mode, the enable switch on the teach pendant becomes enabled, and
enters close status by gripping the switch to neutral.
In EXT mode, the enable switch on the teach pendant becomes disabled, but the
safety door switch, etc. is enabled.
The operational correspondence is shown below.
