VLT AutomationDrive FC 301/302
Programming Guide
Readout of the mechanical power applied to the motor shaft. The base unit is in W.
Parameter 16-24 Calibrated Stator Resistance
Table 845: Parameter 16-24 Calibrated Stator Resistance
16-24 Calibrated Stator Resistance
Default value: 0.0000 Ohm
Conversion index: -4
Shows the calibrated stator resistance.
Parameter 16-25 Torque [Nm] High
Table 846: Parameter 16-25 Torque [Nm] High
16-25 Torque [Nm] High
Default value: 0 Nm
Conversion index: -1
View the torque value with sign, applied to the motor shaft. Some motors supply more than 160% torque. Therefore, the minimum
value and the maximum value depend on the maximum motor current as well as the motor used. This specific readout has been
adapted to be able to show higher values than the standard readout in parameter 16-16 Torque [Nm].
Parameter 16-28 Angle Error
Table 847: Parameter 16-28 Angle Error
16-28 Angle Error
Default value: 0 °
Conversion index: -2
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.
