MX4660 Connection Diagram

When implemented properly, the MX4660 can be used to power four 2 phase (1.8°) stepper motors of NEMA 17,
23, 24, and 34. In addition, it can also allow controls of optional external devices via the built-in digital inputs,
digital outputs, and the opto-isolated analog output. Figure 21 illustrates the MX4660 connection diagram with
4 stepper motors. External devices through the MX4660 I/O connections are optional at a user’s choice. If you
need to use input5, input6, input7, input8, output3, output4, output5 and output6, a 2

nd

parallel port or an

external device like SmoothStepper is required.
