sets the motor feedback
direction.
This switch is used during the Auto-Config
process
(see ACONFIG). If Phase 5
of Auto-Config (Direction test) fails,
MFBDIR can be
used to switch the motor feedback direction. The range is 0 to
3:
MFBDIR = 0: normal commutation direction, normal velocity direction.
MFBDIR = 1: inverted commutation direction, normal velocity direction.
MFBDIR = 2: normal commutation direction, inverted velocity direction.
MFBDIR = 3: inverted commutation direction, inverted velocity
direction.
Expanded functionality to MFBDIR.
Values 0 to 3 work with no change.
New values are 4 to 7.
MFBDIR definition:
| Value | bit2 | bit1 | bit0 | Halls-dir | PRD-dir | PFB-dir |
| 0 | 0 | 0 | 0 | normal | normal | normal |
| 1 | 0 | 0 | 1 | inverted | inverted | normal |
| 2 | 0 | 1 | 0 | normal | normal | inverted |
| 3 | 0 | 1 | 1 | inverted | inverted | inverted |
| 4 | 1 | 0 | 0 | inverted | normal | normal |
| 5 | 1 | 0 | 1 | normal | inverted | normal |
| 6 | 1 | 1 | 0 | inverted | normal | inverted |
| 7 | 1 | 1 | 1 | normal | inverted | inverted |
If the motor leads/motor stator are phased
incorrectly, then setting
MFBDIR=1
will solve the problem. If the feedback device is connected/phased
incorrectly, you have to set
MFBDIR=3,
which changes both the commutation
and velocity loop directions.
