Description

  • 01h: Field-forming components of the current
  • 02h: Torque-forming components of the current
  • 03h: Phase current in phase A (stepper motor) or U (BLDC motor)
  • 04h: Phase current in phase B (stepper motor ) or W (BLDC motor)
Note: Motor currents I_d (subindex 01h) and I_q (subindex 02h) are only displayed if closed loop was activated; the value 0 is otherwise output.
