FMD2740C stepper motor driver1,Brief introductionFMD2740C 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,Features1. High-performance, low price 2. Bipolar constant current chopping mode3. Power supply voltage 12 to 50VDC 4. High-speed optocoupler signal isolation input5. 20kHz chopping frequency 6. Subdivision precision 2\8\16\32\64\128\10\20 optional 7. Electrical input signal is TTL compatible8. Stationary current is automatically reduced by half9. Shape design is convenient for installation 10.Maximum drive current is 4A11.Drive any 4A phase current of 2-phase or 4-phase hybrid stepping motor 3,ApplicationsSuitable for a variety of small and medium-sized automation equipment and instruments,for example: Small engraving machine, SMT machine, etc. 4,wiring definedWeak signal interface SignalFunctionSP+Pulse signal + endSP-Pulse signal – endDIR+Direction signal +endDIR-Direction signal-endEN+Enable signal +endEN-Enable signal -end Strengths connection portSignalFunctionVIN+12to50 v dc power supply input +end,it is recommended to use 36V3AGNDDC power supply connection groundA+Stepper motor A + Phase terminalA-Stepper motor A – Phase terminalB+Stepper motor B+ Phase terminalB-Stepper motor B – Phase terminal NOTE: 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 use of the environment and parametersCooling methodNatural cooling or forced air cooling Use of the environmentOccasionsAvoid dust, oil mist and corrosive gasesTemperature0°C-+50°CHumidity40-90%RHVibration6m/s2 MAXStorage temperature-20°C-+65°CWeight250g 6,Mechanical installation size 7, Power supply The supply voltage can work normally in between DC12V-50V, FMD2740C 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. 8,Attenuation of the DIP switch settingsDecay modeSW1SW2Slow decayOFFOFFMixed decayONOFFFast decayOFFON 9,Subdivision DIP switch settings 10,Current DIP switch settings 11,Drive motor controller wiring diagram12,Electrical wiringThe FMD2740C 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: 13,Matching of the drive and motorFMD2740C 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 selectedGenerally 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 setFor 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.
