Emergency Stop Input (Emg); External Power Input (Vex) - Advantech PCI-1220U User Manual

3.10 Emergency Stop Input (EMG)

When emergency stop input signal is enabled, the output of the drive
pulse for all axes will be stopped, and error bit of main status register will
be set to 1. The operation of emergency stop input is positive or negative
triggered can be determined by JP5 on the board.
This signal should be used in combination with external power
DC12 ~ 24V. The response time of circuitry should take about 0.25 msec
because of the delay of photo coupled and RC filter.

Note

3.11 External Power Input (VEX)

External power is necessary for all input signals of each axis. Please
apply DC12~24V voltage as your need. Current consumption of each
point for input signal is DC12V = 3.3 mA, DC24V = 7 mA.
