XLT50-D/XLT50-S 3-AXIS STEPPER DRIVE

Control XLT50 Drive
Input Configuration
The XLT50 drive is available in two versions:
•
XLT50-D Differential step/direction inputs
•
XLT50-S Single-ended step/direction inputs
The use of differential inputs gives the option of good electrical noise immunity and finds
greatest use where control signals have to be routed long distances in electrically noisy
environments. The single-ended version does not have the same noise immunity, but offers
the choice of a simple control interface.
Table A-2 lists the signal functionality for a differential input drive.
