5.1.4 Detection of spindle with inverse behavior
During setup, a PMSM with an angle deviating by 180 degrees (electrical) can be identified as an in-
verse machine. Such machines are typically PMSM with buried magnets.
For identification, a part of the flux direction identification normally carried out upon startup of a
standing machine (depending on setting of Parameter 645, see Chapter 5.1.1.3 “Determination of the
flux direction at startup”) is carried out during parameter identification.
Parameter
Estimation of flux-direction - inverted 644 is set as follows depending on the identified
machine:
− “0-Off” when a “normal” machine is identified
− “1-On” when a “inverse” machine is identified
If, for example, reliable identification is not possible due to rotation of the machine during parameter
identification, Parameter 644 will remain unchanged.
