Root calculation, faulty output of the SQRT1 function block
Which products are affected?
9300 vector 110 …400 kW SW ≤ V7.0 and 9300 vector 0.37…90 kW V 6.x ≥ SW ≤ V 7.1
What happens?
The analog output SQRT1-OUT always indicates the value 0 %, independent from the value of the analog input SQRT1-IN.
Possible diagnostics?
Comparing the values of the analog signals SQRT1-OUT and SQRT1-IN by means of the function block editor.
Independent from this function restriction you should generally check if all used function blocks are entered in the processing list, as otherwise the values at the outputs of the function blocks will also be incorrect.
Short-term measures/recommendations?
None.
Evaluation:
This function restriction will be detected during commissioning.
