MECHANICAL / ELECTRICAL DESCRIPTION
2-5
Each axis on the module contains digital inputs for the home
L/S, drive fault, positive overtravel L/S, and negative
overtravel L/S. These inputs are connected to faceplate
LEDs. Each of the inputs has a 30 Hz filter and may be 24
volts A-C or D-C. Refer to figure 2.4 for a typical input circuit.
Each axis contains a watchdog output which can be used by
the module to disable the drive if the module falls. The
watchdog output is a normally open relay contact. See figure
3-7.
