L_WndCalcDiameter does not calculate at very low winding speeds (corrected from V2.17)
Corrected from: LenzeWinder.lib version 1.2.2.0 included in the Engineer catalogue from 2.17.0.0
Response of the new version?
Diameter calculation is also executed at very low speeds.
Which products are affected? The L_WndCalcDiameter function block from the LenzeWinder.lib library with a lower version than 1.2.2.0.
What happens? At very low winding speeds, the current diameter L_WndCalcDiameter.dwDiameter and L_WndCalcDiameter.dnDiameter does not change.
When does the problem occur? When the internal winder speed is reduced to a value lower than approx. 1rpm. The internal speed is calculated from the motor speed dnActualMotorSpeed_s divided by the gearbox factor dnGearNumerator/dnGearDenominator.
Diagnostics options?
If 'freezing' of the diameter calculation only occurs at low winder speeds, this is an indicator of the response.
Short-term measures/recommendations? None.
Evaluation: The response only occurs with winders with unusually great gearbox factors. Only if winding at very low speeds takes place over a longer period, an incorrect diameter value has an impact on the torque or speed provided.
