The DV422 is full digital 2-phase stepper driver based on DSP control , the drive voltage ranges from 12V to 36VDC. It is designed for use with the 2-phase hybrid stepper motor of all kinds with 39mm to 42mm outside diameter, regulated phase current under 2.2A. Due to the perfect use of the constant current chopping circuit, the motor enables to run smoothly .The highest micro step is 40000ppr.

1) 8 channels constant angle, constant torque micro steps, highest micro step: 6400ppr
2) Highest response frequency: 200Kpps
3) Current of winding will be reduced by approximately 50% when no step pulse command is received for 1.5 seconds
4) Opto-isolated signal I/O
5) Drive current is adjustable in 8 channels from 0.3A/phase to 2.2A/phase
6) Single power supply from 12V to 36VDC
7) Better to overcome the problem of low frequency vibration
8) Dimension : 86×21×56mm3; Net Weight : 0.1Kg
