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.
