D309 Proceed to phase 4
If the drive controller is not in phase 4 (bb), then it is not possible to
executed command P-0-0524, D300 Commutation adjustment
command.
D310 Input master password
No master password was input.
D311 Commutation offset could not be determined.
The Automatic Commutation Adjustment has tried to determine the
commutation offset. That has failed.
Cause:
The motor could not move freely enough.
Remedy:
Check whether the motor is blocked.

D312 Motion range exceeded during commutation
A range of +/- 1 pole pair distance is defined, within which the axis may
move during the Automatic Commutation adjustment. If this range is
exceeded, this error message appears.
Cause:
1. The drive enable has been set while the axis was still in motion.
2. The axis has been moved by a mechanical force.
3. Parameters P-0-0560 Commutation adjustment current and P-0-0562
Commutation adjustment cycle time are set too high. Possibly the
mechanical properties of the axis, like friction or weight load, have
changed.
Remedy:
1. Wait until the axis stands still and set the drive enable once again.
2. Inhibit the influence of the mechanical force.
3. Reduce the parameter values for P-0-0560 Commutation adjustment
current and P-0-0562 Commutation adjustment cycle time. You can
also set them to the default values P-0-0560 Commutation
adjustment current = 25 % and P-0-0562 Commutation adjustment
cycle time = 4 milliseconds. Afterwards, start the command D300
commutation adjustment to evaluate once again the optimal
parameters.
