Getting Start. Leadshine MX 3660

Below you will find brief information for Multi-axis Stepper Drive MX 3660. The MX3660 is a multi-axis stepper drive that is specially designed to allow for easy and rapid implementation of multiple axis stepper solutions. It is capable of driving multiple 2-phase stepper motors in frame sizes 17, 23, 24, and 34. It features anti-resonance, multi-stepping, digital smoothing, options of different configurations for each axis, automatic idle current reduction, and easy configurations of micro stepping and output currents via DIP switches.

Getting Start

To get start you need one PC with parallel port (DB25), three stepper motors (one is also ok) and a DC power supply for the first time evaluation. The MX3660 is designed for those applications using

Mach3 as the motion controller. However it is also possible to control it a traditional motion controller which generates the Steps & Direction command.

Connecting Power Supply

The power of the MX3660 can be connected as follows.

Power Connections of the MX3660

Connecting Motor

The drive module of the MX3660 is designed for 2-phase stepper motor. It can work with Leadshine

42HS series (NEMA 17), 57HS series (NEMA 23), 86HS series (NEMA 34) stepper motor which has the

A+, A-, B+ and B- lead. Just connect these leads to the corresponding terminals of the MX3660 as follows. Please refer to the motor’s datasheet for the wire color definition.

Connecting the Emergency Stop Switch

The emergency stop input of the MX3660 is used to disable the power stage of the motor output. By default this input is active high, meaning that you need connect a normal close switch between the

Estop+ and Estop- terminal. If it is not required for your system, just connect a wire between them.

Note1: The E-Stop is only active when a PC with Mach3 / EMC is adopted as the control system.

Note2: It is possible to change the active level of the E-stop input in MACH3 or EMC2.

Connecting the Home / Limit Switch

The home / limit input of the MX3660 can be connected as follows. By default these digital inputs are active at low level, meaning that you need to connect them to the normal open switches. If these inputs are not required for your application, just leave them unconnected.

Note1: These inputs are only active when a PC with Mach3 / EMC is adopted as the control system.

Note2: It is possible to change the active level of these inputs in MACH3 or EMC2.

Connecting the Inverter

Most of the Inverter in the market can be controlled by several digital inputs and one analog input.

The MX3660 has four general purpose digital outputs of OC (open collector) type. The actual connection between the MX3660 and the inverter depends on the control mode of the inverter. The following connection diagram use one output to start the spindle, one output to stop the spindle and the 0-10V output to control the spindle speed.

Note1: These outputs and the 0-10V output are only active when a PC with Mach3 / EMC is adopted as the control system.

Note2: It is possible to change the active level of these outputs in MACH3 or EMC2.

Using External Step & Direction Signal

Though the MX3660 has been special designed for those software that use the PC and parallel port as the motion controller, you can also use external step and direction signal to control it.

Note1: The pulse switch should be on when using external step & direction as command source.

Note2: OC (open collector) output is recommended.
