MC660-Mini Two-phase 60/86 Stepper Driver

Product Overview

The MC660-Mini is a digital two-phase hybrid stepper motor driver that utilizes the latest 32-bit DSP control technology. It can be customized according to user needs with any subdivision between 400 and 25600 and any current value within the rated current. Additionally, it features an internal motor parameter auto-recognition function, allowing it to adopt corresponding operating parameters for different motors, resulting in very smooth operation and minimal noise.

Features

Voltage input range: DC 20V to 50V Maximum peak current: 5.6A Subdivision range: 400 to 25600 ppr Pulse form: Pulse + Direction Pulse response frequency: 0 to 200KHz Automatic motor parameter tuning function With overvoltage, overcurrent, tracking error overrun and other protection functions.

Driver Function Description

Driver Functions	Operating Instructions
Operating Current Setting	The output current of the driver is set by three DIP switches SW1-SW3, with a total of 8 levels of output current. For specific output current settings, please refer to the driver panel instructions.
Automatic Half-Current Function	Users can set the driver's automatic half-current function via SW4. OFF means the static current is set to half of the dynamic current, ON means the static current is the same as the dynamic current. Generally, SW4 should be set to OFF to reduce heating of the motor and driver and improve reliability. About 0.3 seconds after the pulse train stops, the current automatically reduces by 50% (actual value 55%), theoretically reducing heat generation by 65%.
Microstep Subdivision Setting	The microstep subdivision of the driver is set by four DIP switches SW5-SW8, with a total of 15 microstep levels. When setting the subdivision, the driver should be stopped first. For specific microstep subdivision settings, please refer to the driver panel instructions.
Indicator Lights	The driver has two indicator lights: red and green. The green light is the power indicator and stays on when the driver is powered. The red light is the fault indicator and stays on when overvoltage or overcurrent faults occur. The red light turns off after the fault is cleared. When a fault occurs, only power cycling and re-enabling can clear the fault.
Signal Interface	PUL+ and PUL- are the positive and negative terminals of the control pulse signal; DIR+ and DIR- are the positive and negative terminals of the direction signal; ENA+ and ENA- are the positive and negative terminals of the enable signal.
Motor Interface	A+ and A- connect to the positive and negative terminals of the stepper motor's A-phase winding; B+ and B- connect to the positive and negative terminals of the B-phase winding. Swapping the A and B phase windings reverses the motor direction.
Power Interface	Powered by DC power supply, the recommended operating voltage range is 20V-50VDC, with a recommended operating voltage of 36VDC and power greater than 100W.
Installation Instructions	The driver dimensions are: 118×75.5×35.5mm with mounting hole spacing of 112.5mm. It can be installed horizontally or vertically (vertical installation is recommended). During installation, it should be mounted tightly against a metal cabinet to facilitate heat dissipation.
