AMP-304C
3.3 Motion I/O Interface Signal
3.3.1 Emergency Stop Input (EMG)
The AMP-304C provides an EMG signal, common with DI. If one
of the EMG signals is triggered, all motion control commands will
be stopped immediately. Another way to stop operation of each
motor immediately is by transmitting an external EMG signal via
the DIN-304C to a servo or stepper motor driver. Refer to the DIN-
304C User’s Manual for more details.
3.3.2 Mechanical Signal Input
The AMP-304C provides some dedicated input pins for mechani-
cal signals such as original position signal (ORG), direction end
limit signals (PEL/MEL), and direction ramping-down point detec-
tion signals (SD).
