    NEMA 17 to 34 in full power with high reliability. The MX4660 is easy to configure without the use of software. With the four DIP switches (one for each axis), a user can easily configure the output current to one of the eight 1.41-6.0A settings, and the micro stepping resolution to one of the eight 200-12,800 (full to 1/64 step) settings.

     A 24-54 VDC power supply.  Up to 4 stepper motors depending on how many axes that MX4660 will power in your application.  A source of step signals, such as a motion controller, PLC, or a PC-based control system (Mach 3, EMC, etc.).

  • Page 8: Connecting A Power Supply

    Connecting a Power Supply The power supply connector is located at the upper left side of MX4660 (“CN2” in Figure 3). The power supply of the MX4660 can be connected as illustrated in Figure 4. Although MX4660’s working voltage is 20-60 VDC, we suggest the use of a 24-54 VDC power supply to leave room for back EMF voltage charge back during motor deceleration.

    “Charge Pump”, a watchdog timer to enable/disable the MX4660. When the charge pump feature is turned on, the MX4660’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 MX4660 will be activated without such verification.

  • Page 12: Setting The "Smoother" Switch

    “Smoother” feature may or may not have obvious effect (but at least no hurt for the bottom line). Turning on this switch or off is totally your choice. By default, the MX4660 smoother is set to off.

  • Page 13: Configuring The Output Current

    The step and direction pin connections are required. Step signals are sent to MX4660 via pin 2, 4, 6, 8 of the DB25 connector. Direction signals are sent to MX4660 via pin 3, 5, 7, 9. Refer to Figure 13. Leadshine Technology Co., Ltd Leadshine America, Inc.

  • 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 MX4660, 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.

    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.

  • Page 16: Connecting The Digital Outputs

    The 6 general digital outputs are located at the Digital Output Connector (Figure 3) of the MX4660, named as Output 1, Output 2, Output 3, Output 4, Output 5 and Output 6. They can be used to control a DC relay for coolant in a CNC router, or for other purpose such as expanding the and 6 axis.
