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. This has failed.
Cause:
1. The motor could not move freely.
2. Direction of movement of the encoder is incorrect.
3. Incorrect polarity of the motor.
4. Axis mechanically blocked.
5. Brake applied.
6. Axis is in endstop position.
Remedy for:
1. Check mechanically whether the motor can be moved.
2. Check the encoder. Invert the direction of movement of the encoder,
if necessary.
3. Check motor connection to the controller.
4. Release mechanical blocking.
5. Check brake and control signals. The brake must be released
immediately when the controller enable signal is set.
6. Make sure the axis does not remain in endstop position.

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.
