Hardware installation manual of the multi-axis drive MX3660

Introduction to the MX3660

Based on the latest DSP technology and adopting Leadshines' advanced control algorithms, Leadshine

MX series was specially designed to allow easy and rapid implementation of multiple axis stepper solutions. With up to 60VDC working voltage and output current to 6.0A, Leadshine multi-axis stepper drives are capable of driving multiple 2 phase stepper motors in frame size 17, 23, 24, and 34.

Leadshine multiple axis stepper strives can drive stepper systems at excellent low-to-high speed performance with high precision, extra low motor heating, smooth movement, and low motor noise.

They are featured with anti resonance, multi stepping, digital smoothing, options of different configuration for each axis, automatic idle current reduction, and easy configurations of micro stepping and output currents via DIP switches. Their integrated breakout board and built-in IO's offer easy implementation for many applications at very effect costs.

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.

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.

Typical Connections

Configuration

For the motor drive module, you only need to configure the peak current and micro step resolution for the stepper motor. A 6-bit DIP switch is used for this purpose. Usually, the RMS current of the drive should be equal to the motor’s phase current (or rated current). In practice, the setting current

(RMS value) can be less than the motor’s phase current if the actual torque is capable of moving the load at required motion velocity and acceleration. The micro step resolution setting is depending on the application. Higher resolution that is greater than 1600 PPR only introduces more smooth motion.

Power Supply Selection

To achieve good driving performances, it is important to choose a suitable supply voltage and use a matching current value. Generally speaking, supply voltage determines the high speed performance of the motor, while output current determines the output torque of the driven motor (particularly at lower speed). Higher supply voltage will allow higher motor speed to be achieved, at the price of more noise and heating. If the motion speed requirement is low, it’s better to use lower supply voltage to decrease noise, heating and improve reliability.

Regulated or Unregulated Power Supply

Both regulated and unregulated power supplies can be used to supply the drive. If regulated power supplies (such as most switching supplies.) are indeed used, it is important to have large current output rating to avoid problems like current clamp, for example using 4A supply for 3A motor-drive operation. On the other hand, if unregulated supply is used, one may use a power supply of lower

8

Hardware installation manual of the multi-axis drive MX3660 current rating than that of motor (typically 50%～70% of motor current). The reason is that the drive draws current from the power supply capacitor of the unregulated supply only during the ON duration of the PWM cycle, but not during the OFF duration. Therefore, the average current withdrawn from power supply is considerably less than motor current. For example, two 3A motors can be well supplied by one power supply of 4A rating.

Selecting Supply Voltage

Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. However, higher voltage may cause bigger motor vibration at lower speed, and it may also cause over-voltage protection or even drive damage. Therefore, it is suggested to choose only sufficiently high supply voltage for intended applications, and it is suggested to use power supplies with theoretical output voltage of drive’s minimum + 10% to drive’s maximum – 10%, leaving room for power fluctuation and back-EMF.

Protection Functions

To improve reliability, the drive module incorporates some built-in protection functions. It uses one red LED to indicate the protection type. The periodic time of red is 4 s (seconds), and the blinking times of red LED indicates what protection has been activated. Because only one protection can be displayed by red LED, so the drive will decide what error to display according to their priorities. See the following protection Indications table for displaying priorities.

Over-current Protection

Over-current protection will be activated when continuous current exceeds the limit or in case of short circuit between motor coils or between motor coil and ground, and RED LED will blink once

within each periodic time.

Over-voltage Protection

When power supply voltage exceeds the limits, protection will be activated and red LED will blink twice within each periodic time.

!

Caution

When above protections are active, the motor shaft will be free or the LED will blink. Reset the drive by repowering it to make it function properly after removing above problems. Since there is no protection against power leads (﹢,﹣) reversal, it is critical to make sure that power supply leads correctly connected to drive.

Otherwise, the drive will be damaged instantly.

Frequently Asked Questions

In the event that your drive 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. It is important to document each step in the troubleshooting process. You may need this documentation to refer back to at a later date, and these details will greatly assist our Technical Support staff in determining the problem should you need assistance.

Many of the problems that affect motion control systems can be traced to electrical noise, controller software errors, or mistake in wiring.
