Plausibility test During plausibility testing, some machine parameters and part of the wiring
are checked.
Encoder line count
Number of pole pairs
Rotational direction of the electrical field
Traverse distance per electrical revolution
The following messages can appear during the plausibility test:
8630 Field orient. successful
Indicates that the field angle was successfully determined and stored in
MP_motPhiRef.
8B10 Wrong traverse direction
Indicates that the rotational direction of the electrical field does not match
the counting direction of the encoder.
Error fix: Change the entry in the machine parameter MP_motDir.
8B20 Error field orientation
Indicates that no usable measurement results could be determined. One
common reason for this is that the parameters for the encoder are incorrect.
A further cause could be that the motor is moving against a resistance (e.g.
brake is still active, bellows, limit stop) or that the mechanics are too stiff.
Determination of the field angle with plausibility testing is recommended
for initial setup, new designs, and other similar situations.
