Select SLC 500 I/O Modules 33
output (TPO), is sent from the module to the SLC data table. Your application logic
must access the CV value in the data table and send the analog or TPO data to an output
module to close the loop. The module is compatible with SLC 5/02 and higher
processors.
Motion Control Modules
Stepper Control Module
The 1746-HSTP1 is a single-axis stepper controller capable of providing up to 250 kHz
pulse train output for micro-stepping applications. The module can interface directly
with a quadrature encoder to monitor position. Built-in loop back diagnostics provide
monitoring of pulse train commands. Programmable modes of operation eliminate the
need to set DIP switches.
