Party Servo Amplifiers to the GPIO4D
2. Wiring GPIO4D External Drive Fault Input
The GPIO4D will detect an external drive
fault if the Fault input is not closed to the voltage that is opposite that of the signal connected
to the Fault COM. For instance, if the FaultCom is connected to +5VDC, the Fault input must
be connected to 5COM or a drive fault will be reported. Which is connected to which does
not matter as long as they are connected to the opposite of each other. I.e. if the Fault input
is connected to +24VDC, the Fault COM must be connected to 24COM or an external drive
fault will be detected and the axis will be disabled by the GPIO4D.
3. Enabling your drive fault inputs
From the main screen, press the alt-i keys to bring up
the Realtime I/O display. Starting with input 17, use the arrow keys to select inputs 17-20
and, one input a time, press the ctrl-alt-i keys simultaneously to remove the bar over the
input in the display.
4. Testing your drive fault inputs
If your Drive Fault inputs are wired correctly, inputs 17-20
should be green. If any are not, either your drive is reporting a fault or the drive fault input for
that axis is wired incorrectly.
