Programming Guide | VLT® AutomationDrive FC 301/FC 302
Setup: All setups
Data type: Int16
Readout of the deviation between sensorless rotor angle estimation by motor controller and real rotor angle based on encoder reading.
The parameter is only activated if options in parameter 1-01 Motor Control Principle is set to [2] Flux Sensorless and parameter 1-10
Motor Construction is set to [1] PM, non salient SPM or [2] PM, salient IPM. The encoder source used for comparison must be selected
in parameter 7-00 Speed PID Feedback Source. To obtain an accurate reading of parameter 16-28 Angle Error, the motor angle offset
must be set in parameter 1-41 Motor Angle Offset. Rotor detection is configured in parameter 7-90 Position PI Feedback Source, which
is activated using the setting in parameter 1-70 Start Mode in Flux with motor feedback. Parameter 7-90 Position PI Feedback Source
must be set to [0] Motor feedb.P1-02. The encoder is then only used for comparison while position control is based on the estimated
sensorless position. This enables the measurement of the accuracy of position control in sensorless mode.
