  • Three phase trapezoidal brushless, four quadrant operation
  • Highly efficient and reliable power MOSFET output stage
  • Single DC power supply
  • EC Commutation encoder Feedback
  • RD Differential reference Control Mode
  • Five LED (Red/Green) operating status signals


  • AH Armature + hall Feedback
  • EH Encoder + external hall Feedback
  • H0 Hall (only) Feedback
  • RO Resolver Feedback
  • CD Clock + Direct
  • PD PWM + Direct
  • IO Demand current (torque mode)
