FMD2740C CNC Stepper Motor Driver 18-50VDC 1.4-5.6A 256 microstep for Nema17 Nema23 stepper motor cnc router milling engraving machine

FMD2740C driver is suitable for driving small and medium-sized phase current is less than 5.6A 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.

Power supply

The supply voltage can work normally in between DC18V-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-36V DC supply , avoid the grid fluctuations over drive voltage operating range.

Electrical wiring

The FMD2740C driver can drive all current less than 5.6A 4-wire, 6-wire or 8-wire 2-phase / 4-phase motors.
