Extrapolation of the friction characteristic

Which products are affected?
ESP-SPAC-Wnd1 – Winder Software Package V2.0

What happens?
If the actual speed value is larger than 100% the output values of the L_WndFrictionCurve function block become inexact.

When does the problem occur?
When selecting a friction characteristic from the table values through the input bCurve = TRUE. In addition, the value at input (nNAct_a) of the function block must be larger than 100 %.
This restriction only occurs if the function block is used without the template.

Possible diagnostics?
None.

Short-term measures/recommendations?
None.

Evaluation:
This restriction will never occur in practice when using the templates since the motor control (MCTRL) can only be stimulated with a maximum speed setpoint of 100 %.
