Theme: Product Procurement & Buyer Guide
Engineers need a stepper controller that integrates seamlessly with existing SLC 500 systems. The 1746-HSTP1 meets this need perfectly. It works with SLC 5/01, 5/02, and 5/03 processors without issue. It also supports SLC 5/04 and 5/05 controllers for larger applications.
This module provides a trapezoidal velocity profile for smooth acceleration. You can set acceleration from 1 to 2000 pulses per second. This feature reduces mechanical stress on your equipment. The module offers an absolute positioning count over 8,000,000 counts.
Procurement managers value the module’s compatibility with fixed style hardware. It works with a 2-slot expansion rack for flexible system design. The 1746-HSTP1 uses a 5V DC backplane current of 200 milliamps. It also draws 90 milliamps at 24 volts for auxiliary power.
The module interfaces directly with stepper motor drivers for easy setup. It supports differential encoder feedback with +5 or +15V signals. This flexibility simplifies integration with various encoder types. The input frequency reaches 250 kilohertz for high-speed applications.
Application engineers benefit from the module’s programmable modes. You do not need DIP switches for configuration. This design reduces setup time and potential errors. The module uses a 4 ms update time for responsive control.
The 1746-HSTP1 provides loopback diagnostics for system verification. This feature helps maintain operational integrity during production. The module has a step response of 100 milliseconds in. It delivers a 2.5 millisecond output for fast reactions.
Theme: Expert Technical Evaluation & Performance Review
The 1746-HSTP1 delivers high performance for critical motion tasks. It generates a pulse train output of 250 kHz for micro-stepping. This speed supports precise positioning in demanding industrial environments. The module achieves an acceleration step rate of 4 milliseconds or less.
Thermal dissipation remains low at 1.5 Watts for all conditions. This efficiency reduces heat buildup inside the control cabinet. The module operates within an inlet air temperature of 0 to 60 degrees Celsius. It can withstand storage temperatures from -40 to 85 degrees Celsius.
Environmental tolerance includes relative humidity from 5 to 95 percent. The module functions reliably at altitudes up to 2000 meters. These specifications make it suitable for diverse factory floor conditions. The estimated dimensions are 5 x 2 x 6 inches for easy mounting.
The module weighs approximately 15 ounces for simple handling. It uses a 1746-HT or 1746-HCA I/O connection for wiring. The pulse train switching current ranges from 7 to 30 milliamps at 5V DC. This range ensures compatibility with standard translator circuits.
The 1746-HSTP1 does not implement closed-loop control. It uses encoder feedback to verify movement against the user program. This approach provides reliable position verification without complex tuning. The module interfaces with differential input translators and single-ended TTL.
Engineers can integrate this module into larger PLC systems. It works with the 1746-ASB module for remote rack applications. This scalability makes it valuable for expanding production lines. The module supports absolute positioning beyond 8,000,000 counts for long travel.
The feedback hardware adapts to any frequency up to 250 kHz. This adaptability ensures consistent performance with varying encoder speeds. The module provides digital outputs for the translator with a 4 ms update. This timing enables precise coordination with other system components.
