·  1 x FMD2725A Stepper Motor Driver

FMD2725A stepper motor driver

1,Brief introduction

    FMD2725A is using THB7128 chips produced by Japan's Sanyo, after several optimization of high subdivision of R & D and production of the 2 phase stepper motor drive, suitable for driving small and medium-sized phase current is less than 2.5A 2-phase or 4-phase hybrid stepping motor. Due to the adoption of the new bipolar constant current chopper drive technology, using the same motor can output more speed and power than other drivers. The segmentation function make the stepper motor running accuracy improved, reduces vibrations and noise reduction.

2,Features

1.High-performance, low price.            

2.Bipolar constant current chopping mode.

3.Power supply voltage 12 to 40VDC.

4.High-speed optocoupler signal isolation input.

5.20kHz chopping frequency.     

6.Subdivision precision 1, 2, 4, 8, 16, 32, 64,128 optional.  

7.Electrical input signal is TTL compatible.     

8.Stationary current is automatically reduced by half.

9.Shape design is convenient for installation.      

10.Maximum drive current is 2.5A.

11.Drive any 2.5A phase current of 2-phase or 4-phase hybrid stepping motor.      

3,Applications

Suitable for a variety of small and medium-sized automation equipment and instruments , for example: Small engraving machine, SMT machine, etc.

6,The use of the environment and parameters

7,Power supply

The supply voltage can work normally in between DC12V-40V, FMD2725 driver can use ordinary switch DC power supply, can also be used for transformer and the bridge rectifier and filter capacitor, capacitance desirable 2000U to 5000U. Note rectified voltage ripple crest does not exceed 40V.Recommended the user to use the 24V-32V DC supply , avoid the grid fluctuations over drive voltage operating range.

Note:

1. Wiring should pay attention to the power of positive and negative Do not be reversed;

2. In order to reduce costs, multiple drives can share a power supply. But it should improve the rated power and rated output current of the power and attention to cooling.

10,The current setting

 Refer to the case of silk-screen diagram, clockwise current increases, the maximum 2.5A, counterclockwise current is reduced, minimum 0.5A.
