stepper drive, turn off the Charge Pump (page 12) and keep sending 10 KHz signals to Pin 16 of the DB25
connector while the controller works properly. In this scenario, the “Charge Pump LED” on the MX4660 will be
turned on to indicate that everything is fine. When no such signal received, MX4660 will be disabled with the
“Charge Pump LED” light off, to prevent from any further action caused by controller malfunction for connected
stepper motors and external devices. Read “Enabling / Disabling Charge Pump” on page 12 for additional
information.
Connecting the DB25 PWM Pin
The PWM pin connection is optional.
The MX4660 can take PWM signals from the controller, through Pin 14 of
the DB25 connector, transform it into an analog signal, and output as analog voltage signal at the “0-10V” pin of
the analog output connector (Figure 3). This will allow the control of an external analog device such as a VFD for
spindle speed control in a CNC router.
Optional Connections for Inputs/Outputs
The MX4660 4-Axis stepper drive is equipped with 8 built-in digital inputs, 6 digital outputs, and one 0-10 V
analog output. Those connections are totally optional and not required to make the MX4660 work.
Connecting the Digital Inputs
The digital input connections are optional.
The 8 general digital inputs are located at the Digital Input Connector
(Figure 3) of the MX4660. They are named as Input 1, Input 2, Input 3, Input 4, Input 5, Input 6, Input 7 and
Input 8. They can be used for any purpose such as connecting limit/home switches.
Input5, 6, 7, 8 are 12V sourcing (10mA MAX). Connect one end of your device wire to the “Input X” (X can be 5,
6, 7, or 8) pin, and the other wire to “GND” pin next to the input pin (for one wire device, short it to GND).
On Figure 14, it shows how to connect a home/limit switch to digital input “Input 5” to “input 8”. Refer to figure
16 for more information about their interface circuit.

Pulled up voltage or the power voltage of the opto-couplers for Input1, Input2, Input3, Input4 is adjustable,
depending on the input voltage of OPTO1 and OPTO2.
This design makes digital inputs can work with external devices NOT only rated at 12 VDC with higher reliability
and more flexiblity, such as working with proximity sensors rated at different voltages. Figure 15 shows how to
connect these inputs and their interface circuit. See “Appendix A: MX4660 Connection Diagram” on page 20 for
more information.
