Adopting the THB6600 chip manufactured by Japan Toshiba,FDM2440B is a high sub-division two-phase step motor driver developed by many times optimization,which is suitable to drive the small and medium phase(the two or four phase current lower than 4A)hybrid step motor. Comparing with other driving mode,the new style bipolar constant current chopping driving technology enables the FMD2440B output higher speed and power when you use the same motor.Its sub-division feature improves the motor operating accuracy,decreases the shaking and reduces the noise.SpecificationHigh performance ,lowe priceBipolar constant current chopping modeSupply voltage 12-50VDCHigh-speed optocoupler signal isolation input.20Khz chopping wave frequency Subdivision accuracy 126.96.36.199.16.choosableAutomatic current halving in restLightweight design for easy istallationMaximum drive cuttent 4AIt can drive any 4A phase current look for the two-phase or 4-phase hybrid stepping motors.What is in box ?1 x CNC Single Axis FMD2440B 2 Phase 4.0A Stepper Motor Driver Board Controller
