Description

The Allen-Bradley 1746-HSTP1 is a stepper controller module. 

A single-slotted module capable of operating a wide variety of SLC 500 series processors. 

With a differential encoder motion that is programmable for more than 8.000.000 counts of absolute position.

The 1746-HSTP1’s feedback hardware adapts up to 250 kHz of any frequencies. 

It can provide 250 kHz pulse train output for micro-stepping applications. 

It uses loopback diagnostics and differential incremental encoder feedback devices. 

The 1746-HSTP1 provides a differential feedback that interfaces directly to +5 or +15 V encoders. 

The module has a 5″ x 2″ x 6″ (13 cm x 5 cm x 15 cm) estimated dimension and weighs 15 oz (0.43 kg) approximately. 

Programmable modes of operation reduce the need for setting a DIP switch.

The 1746-HSTP1 module has a 200 mA back-plane current at 5 volts and 90 mA at 24 volts. 

It has a 5V DC differential encoder or 12-24V DC single-ended auxiliary inputs. 

It provides a digital output for the translator with a 4 ms module update time. 

The controller module has a 7 – 30 mA at 5V DV pulse train switching. 

This stepper controller module interface directly to encoders with differential feedback with +5 or +15V signal. 

It is also compatible with transistors with differential input translators, single-ended TTL and interface for opto-couplers.

This module does not include DIP switches for setting and configuration.

The module provides quick operational diagnostics through its embedded LED indicators that provide feedback regarding programming errors, 

normal and abnormal operation and a faulted system. 

This module also has built-in loop diagnostics that monitors the pulse train commands provides to the module’s translator.
