Absolute Encoder Alignment Error E0406
Absolute encoder used for field orientation initialisation has failed to latch an alignment angle.
Possible causes for this error are:
1. Encoder is faulty. Power cycling the drive/encoder may resolve the issue.
2. Drive is faulty. Please contact ANCA Motion for support.
Field Orientation Alignment in Progress I0409
Field Orientation Alignment is in progress - active stimulus signal (current) has been
commanded to the motor.
Acceleration Observer Excessive Movement E0411
Motor movement exceeded tolerance while executing acceleration observer field orientation.
Possible causes for this error are: 1. Incorrect motor poles configured. 2. Incorrect motor
phase sequence. 3. Incorrect motor encoder line count configured. 4. Incorrect motor encoder
polarity configured.
Acceleration Observer Current Control Error E0412
Sensed motor current is not following the Acceleration Observer alignment current with
sufficient accuracy, Possible causes for this error are:
1. Poorly tuned current loop.
2. DC bus voltage too low.
3. Motor armature cable is disconnected.
4. Motor is faulty.
5. Drive is faulty. Please contact ANCA Motion for support.
Acceleration Observer Excessive Velocity E0413
Excessive velocity detected while acceleration observer is executing. Possible causes for this
error are:
1. Incorrect motor poles configured.
2. Incorrect motor encoder line count configured.
3. Stimulus frequency is too low.
4. Stimulus current is too high.
Acceleration Observer Torque Response Amplitude Low E0414
The fundamental frequency component of the torque response is below the minimum
amplitude threshold. Possible causes for this error are:
1. Stimulus frequency is too high.
2. Stimulus current is too low.
Acceleration Observer Torque Response Amplitude High E0415
The fundamental frequency component of the torque response is above the maximum
amplitude threshold. Possible causes for this error are:
1. Stimulus frequency is too low.
2. Stimulus current is too high.
