9. -10VDC and 10VDC – this voltage is output by the DAC chip and is used to
control the axis motors. +10 volts commands the motors to run at rapid speed
in 1 direction and -10 volts command the motors to run the opposite direction.
10. 5VDC (4.75 to 5.25VDC) – This voltage is produced by the internal power supply
of the computer module, it is used to power the internal functions of the
computer module, servo drives, motor encoders, and the Overlay Interface board
on the pendant. The voltage can be measured between pin 1 of the Overlay
Power Port and the chassis ground on the computer module, as seen on figure
5.7.1b. If this voltage is not correct the computer module will produce a DC
Power Fault that will be identified by the Voltage Fault LED being turn ON, on the
computer module.
