MC556XA Two-phase 57/60 Digital Stepper Driver

Product Overview

The MC556E is a digital two-phase hybrid stepper motor driver that utilizes the latest 32-bit DSP control technology. It can be customized to any subdivision between 400 and 25600 and any current value within the rated current according to user requirements. 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	Set by SW1-SW3 three DIP switches to set the driver output current, with a total of 8 levels. 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 through 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, it is recommended to set SW4 to OFF to reduce the heat generated by the motor and driver and improve reliability. After the pulse train stops, the current automatically reduces after about 0.3 seconds. 50% (Actual value 55% ), theoretically reducing heat generation by 65%。
Microstep Subdivision Setting	Set by SW5-SW8 Four DIP switches are used to set the driver's microstep subdivision, with a total of 15 levels of microstep subdivision. 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, which stays on when the driver is powered; the red light is the fault indicator, which 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- connects to the stepper motor A phase winding positive and negative terminals; B+ and B- connects to the stepper motor B phase winding positive and negative terminals. Swapping the two phase windings can reverse the motor direction. A 、 B When the two phase windings are swapped, the motor direction reverses.
Power Interface	Uses DC power supply, recommended operating voltage range is 20V-50VDC , recommended operating voltage 36VDC , power supply wattage greater than 10 0W.
Installation Instructions	Driver dimensions are: 117 × 78 × 34mm , mounting hole distance is 111mm . 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.
