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.
