The polarities are switched at the input and output of the closed control loop and therefore do not affect the closed control loops in the drive. The motor shaft rotates in a clockwise direction (viewed from the front onto the motor shaft), if there is a positive velocity set value difference and there is no inversion.
Bit pattern:
Bit | Meaning |
|---|---|
0 | Velocity command value 0 = polarity not inverted |
1 | Additive velocity command value 0 = polarity not inverted |
2 | Velocity feedback value 1 0 = polarity not inverted |
3 | Velocity feedback value 2 0 = polarity not inverted |
