Product description:

The Leadshine MX3660 is a high performance 3-axis stepper drive with built-in breakout board and I/O’s based on the latest DSP technology. It is specially designed for EASY and RAPID control of up to three 2-phase (1.8°) in frame sizes NEMA 17, 23, and 24. The MX3660 3-axis stepper drive operates under 20-60 VDC input voltage and can output up to 6.0A current (peak of sinusoidal) per axis. It takes step & direction control and is easy to implement for OEM applications.

By adopting Leadshine advanced stepper motor control technology, the MX3660 3-axis stepper drive can power stepper motors in high precision, at extra smoothness, and with extra low motor heating & noise. It is featured with anti resonance, multi-stepping, vibration suppression, input command smoothing, 50% idle current reduction, etc.

The MX3660 3-axis stepper drive is easy to configure. Via the 6-pin DIP switch of each of the 3 stepper drive modules, a user can easily set the output current and micro step to one of their 8 available settings, 1.45-6.0A and full step - 1/64 respectively. Each axis can have its own current & micro step configurations to satisfy different requirements for the controlled stepper motor. For example, a user can set axis X at 8 micro steps & 6.0A for a NEMA 34 motor, axis Y at 10 micro steps & 4.25 A for a NEMA 24 motor, and axis Z at 16 micro steps & 1.41A to for a NEMA 17 motor.

The MX3660 3-axis stepper drive is integrated with a breakout board with a DB25 connector and built-in I/O’s. This allows convenient, easy and quick connection for controllers (e.g. PC-based control systems, motion controllers, PLC’s…) and external devices (limit switches, VFD…). It simplifies system setup, save installation space & time, minimize wiring, increase reliability, and cut costs. In addition, the MX3660 offers a built-in digital “smoother” to allow filtering/smoothing of "noise" pulses for better system performance (application dependant).
