Module Overview
Chapter Objectives The Module overview will permit you to understand the basic
functions of the Module and hardware requirements.
Stepper Controller The Module, catalog number 1746–HSTP1, is an SLC 500 family
compatible device. It can be used with any SLC 500 Processor.
The Module is configured through the SLC 500 backplane and
requires no switch settings. Motion can be programmed in either
direction for over
±8,000,000 counts of absolute position.
An optional incremental encoder may be used to verify the position
reached by the axis. The Module does not automatically close a
position loop in engineering units. The feedback hardware can accept
frequencies of up to 250 kHz for use as either loop back diagnostics
or differential incremental encoder feedback devices.
The Module can be programmed for either incremental or absolute
moves, depending on the application.
The Module supports two differential outputs, to suit the type of
Stepper Translator used, which provide the following control
commands:
• CW or non-directional pulse output
• CCW or direction signal output
Discrete inputs are provided for:
• External Interrupt
• Home Limit Switch
• Home Proximity Input
• CW Travel Limit Switch Input
• CCW Travel Limit Switch Input
• Pulse Train Enable/Disable Input
