Installation Preparation and System Requirements
Before installing the 1746-HSTP1/E module, engineers should complete the following preparation work:
- Confirm SLC 500 chassis compatibility
- Verify processor communication requirements
- Prepare stepper drive and motor information
- Review motion control wiring drawings
- Confirm external power requirements
- Prepare grounding and shielding plans
Proper preparation helps prevent wiring errors and reduces commissioning time.
1746-HSTP1/E Hardware Installation Procedure
The 1746-HSTP1/E module is installed into an available SLC 500 chassis slot and communicates with the processor through the backplane.
- Power off the SLC 500 chassis
- Select the correct installation slot
- Insert the 1746-HSTP1/E module securely
- Check module seating condition
- Restore system power
- Verify module status indicators
Correct installation ensures reliable communication between the SLC processor and motion controller module.
Stepper Motor Wiring and Signal Connection
Proper wiring is critical for stable stepper motor operation. The 1746-HSTP1/E provides motion output signals that connect to external stepper drives or translators.
- Connect pulse output signals
