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 ■High-performance, low price ■Bipolar constant current chopping mode ■Power supply voltage 12 to 50VDC ■High-speed optocoupler signal isolation input ■20kHz chopping frequency ■Subdivision precision 2\8\16\32\64\128\10\20 optional ■Electrical input signal is TTL compatible ■Stationary current is automatically reduced by half ■Shape design is convenient for installation ■Maximum drive current is 4A ■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. 4、wiring defined Weak signal interface Signal Function SP+ Pulse signal + end SP- Pulse signal - end DIR+ Direction signal +end DIR- Direction signal-end EN+ Enable signal +end EN- Enable signal -end FMD2575A FMD2740A Changzhou RATTM Motor Co.,Ltd Email:sale1@rattmmotor.com Email:sale2@rattmmotor.com MSN:ali900111342 Skype:rattm.motor http:// http://www.aliexpress.com/store/907217 Strengths connection port Signal Function VIN+ 12to50 v dc power supply input +end，it is recommended to use 36V3A GND DC power supply connection ground A+ Stepper motor A + Phase terminal A- Stepper motor A - Phase terminal B+ Stepper motor B+ Phase terminal B- Stepper motor B - Phase terminal This drive does not contain anti-anti-interpolation circuit so non-input positive and negative power supply upside down! Otherwise it will damage the drive! 5、The electrical characteristics Electrical Characteristics (T = 25 ° C) FMD2740A Introductions Min Typ Typee Max Unit Output phase current 0.5 - 4 A Input power voltage 12 36 50 V Logic input voltage 3 5 7 V Logic input current 5 10 15 mA Stepper motor pulse frequency 0 - 150 KHz Minimum pulse time 5 - - us 6、The use of the environment and parameters Cooling method Use of the environment Natural cooling or forced air cooling Occasions Avoid dust, oil mist and corrosive gases Temperature 0℃-+50℃ Humidity 40-90%RH Vibration 6m/s2 MAX Storage temperature -20℃-+65℃ Weight 250g FMD2575A FMD2740A Changzhou RATTM Motor Co.,Ltd Email:sale1@rattmmotor.com Email:sale2@rattmmotor.com MSN:ali900111342 Skype:rattm.motor http:// http://www.aliexpress.com/store/907217 7、Mechanical installation size 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.

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.
