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.

The supply voltage can work normally in between DC12V- 5

FMD27 40A 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 5 0V.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.

FMD 27 40A 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.

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.

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.
