This micro-step driver for 5-phase stepper motor is compatible with all standard
stage models. Able to maintain high torque even in high speed range.
By controlling excitation to the motor, the step angle on 250 divisions at maximum
can be set, and smooth and high precision positioning are possible.


●Low price
●Micro step drive with 250 divisions at maximum


●Compact size and less heat generation
●DC power supply input, constant current drive


●Switch the pulse input method (1 pulse method/2-pulse method)
●Micro step switch with the rotary switch
●Motor drive current switch with the dip switch
●Motor run current with DIP switch


●Automatic current down
  Motor drive current though the dip switch
  settings at stopping maintain the phase
  current to one of 25%, 50%, and 75%.
●Motor excitation OFF function
