Page 4: Introduction
Thank you for choosing the Leadshine MX3660, a high performance 3-axis stepper drive with built-in breakout board and I/O’s based on the latest DSP technology. The MX3660 is specially designed for EASY and RAPID control of up to three 2-phase (1.8°) stepper motors in frame sizes NEMA 17, 23, 24, and 34. It operates under 20-60 VDC supply voltage and can output up to 6.0A current (peak of sinusoidal) per axis. -

A 24-54 VDC power supply. Up to 3 stepper motors depending on how many axes that MX3660 will power in your application. A source of step signals, such as a motion controller, PLC, or a PC-based control system (Mach3/4, EMC, etc.). -
Page 7: Connecting A Power Supply
7. Connecting a Power Supply The power supply connector is located at the upper left side of MX3660 (“CN2” in Figure 3). The power supply of the MX3660 can be connected as illustrated in Figure 4. Although MX3660’s working voltage is 20-60 VDC, we suggest the use of a 20-54 VDC power supply to leave room for back EMF voltage charge back during motor deceleration. -

Page 10: Connecting An E-Stop Switch Or Shorting The Connection
The E-Stop connection is required. The E-Stop connector is located next to the power connector (Figure 3). By default, the MX3660’s activation requires an emergency stop switch connected, or having the two connection pins, “ESTOP+” and “ESTOP-“, shorted. Refer to Figure 10 for how to connect an” E-Stop switch. To short the E-Stop connection, just connect a signal wire between the “ESTOP+”... -
Page 11: Enabling / Disabling Charge Pump
“Charge Pump”, a watchdog timer to enable/disable the MX3660. When the charge pump feature is turned on, the MX3660’s activation will depend on the receiving of 10 kHz signals at pin 16 of the DB25 connector. When the “Charge Pump” feature is turned off, the MX3660 will be activated without such verification. -
Page 12: Configuring Output Current And Micro Step
12. Configuring Output Current and Micro Step The MX3660 allows individual settings of the output current and micro step resolution for each stepper motor, via the 6-pin DIP switches of three stepper drive modules (DP1, DP2, and DP3 on Figure 3). -
Page 13: Configuring The Output Current
Step signals are sent to the MX3660 via pin 2, 4, 6 of the DB25 connector. Direction signals are sent to the MX3660 via pin 3, 5, 7. Refer to Figure 13. Step and direction signal voltage should be 3.3-5 VDC and “Active High”. In the controller configuration, the step width should be configured to a value at least 2.5 uS, and direction setup time needs to be at least 5 uS. -
Page 14: Connecting The Db25 Fault Output Pin
The connected external E-Stop switch in the digital input is pressed. With the receiving of a fault received from the MX3660, a controller can be notified an abnormal event has happened. It can then react, such as shutting down the whole control machine/device for machine damage. - Page 15 Hardware installation manual of the multi-axis drive MX3660 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.

Page 16: Optional Connections For Inputs/Outputs
The 4 general digital inputs are located at the Digital Input Connector (Figure 3) of the MX3660. They are named as Input 1, Input 2, Input 3, and Input 4. They can be used for any purpose such as connecting limit/home switches. Connect one end of your device wire to the “Input X” (X can be 1, 2, 3, or 4) pin, and the other wire to “GND”... - Page 17 EGND Figure 15 Connecting a VFD to the MX3660 Figure 16 shows the relationship of the spindle speed output in Mach3 and analog output of the MX3660. Testing conditions: Used MACH3, settings: PWMBase Freq. = 10, Minimum PWM = 0%, (2) Used “+12Vdc Out”, the 12VDC auxiliary power output on the MX4660 as the power input for “+10Vdc in”...

Emergency stop input (12V Sourcing). When activated, all three drive boards will be shut down and the MX3660 will stop working. The red LED of each drive module will blink three times periodically every 4 seconds to indicate an emergency event signal received. In this case, a fault output will be sent to pin 15 - “Fault”- of the DB25 connector to notify the connected motion controller. -

Hardware installation manual of the multi-axis drive MX3660 Appendix D: Digital Outputs Name Description Output 1 + General purpose output (max 24V@70mA). This pin is connected to pin 17 - “Input 1” - of the DB25 connector. Used to output the digital signal, sent through DB25 “Input 1” from the motion controller, to the connected external device here. -
Page 24: Appendix F: Stepper Drive Module Replacement
Appendix H: Trouble Shooting In the case that the MX3660 doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently. -
