FMD2740Astepper motor driverFMD2740Astepper motor driver1,Brief introduction

FMD2740A FMD2740A driven by Japanese sanyo\'s chip,After multiple optimize R & D and production of high-subdivision 2-phase stepper motor drives, suitable for driving small and medium-sized phase current is less than 4A 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. Segments 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 50VDC

4.High-speed optocoupler signal isolation input

5.20kHz chopping frequency

6.Subdivision style=\"PADDING-BOTTOM: 0px; LINE-HEIGHT: 18px; BACKGROUND-COLOR: rgb(255,255,255); MARGIN: 0px; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; FONT-FAMILY: verdana; WORD-WRAP: break-word; FONT-SIZE: 12px; FONT-WEIGHT: normal; PADDING-TOP: 0px\">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 is4A

11.Drive any 4A 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.

8, Power supply

The supply voltage can work normally in between DC12V-50V, FMD2740A 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 50V.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.

The FMD2740A driver can drive all current 4A 4-wire, 6-wire or 8-wire 2-phase / 4-phase motors, are detailed below 4-wire, 6-wire, 8 wire stepper motor connection:

14,Matching of the drive and motor

FMD2740A driver can drive the domestic and foreign manufacturers of 2-phase or 4-phase motor, in order to obtain the most satisfactory driving, you need to choose a reasonable supply voltage and current setting. Supply voltage determines the level of the high-speed performance of the motor, and the current set value determines the output torque of the motor.

Supply voltage selected

Generally speaking, the higher the supply voltage, the greater the torque motor at high speed, the more it can avoid the high speed out. But another aspect, the voltage is too high will lead to over-voltage protection, and can even damage the drive, but also in the high-pressure work, low speed vibrations.

The output current is set

For the same motor, the greater the current setting, the higher speed, the current motor and drive more heat. So under normal circumstances the current setting into a powered machine warm but not too hot long-term value.

Note:the current settings after you run the motor for 15-30 minutes, if the motor temperature is too high, you should reduce the current settings. If the motor current setting, the motor output torque is not enough to improve heat dissipation conditions to ensure that the motor and drive are not hot.
