The 1746-HSTP1 features five LED indicators on the front panel to diagnose operational errors. These indicators are RUN (system running), CCW (commanding counterclockwise move), CW (commanding clockwise motion), ERR (error), FLT (no configuration file presentinvalid configuration). The module also features IO terminals which supply power to the module and outputs to attached devices. It has an update time of 4 ms. Maximum input frequency for the 1746-HSTP1 is 250 kHz. Additionally, the module provides up to 250 kHz by pulse train output for micro-stepping applications. The module is equipped with loop back diagnostics to monitor the pulse train commands. Backplane current for the module at 5V is 200 mA and at 24V is 90 mA. Thermal dissipation minimum and maximum for the 1746-HSTP1 is 1.50 W. When wiring the system make sure to use 6075C copper wire. Also, make sure to tighten the terminals to 5lbin.
