What happens?
The rPosActual output of the L_LCB_TablePositioning FB indicates the value "NaN".
NaN stands for "Not a number". The indicated value cannot be represented as a floating point number (REAL).
When does this behaviour occur?
The behaviour occurs if the dwGearDenominator parameter (gearbox factor denominator) in the scAxisData structure of the FB is set to 0.
Which products are affected?
L_LCB_TablePositioning function block in the L_LCB_LogicControlBasic library (all versions)
Short-term measures:
Never set the gearbox factor denominator (dwGearDenominator) to 0.
Furthermore, make sure that the scAxisData input of the FB does not remain free since this is the input where the required machine constants (feed constant, cycle length, gearbox factor, ...) have to be set.
No change is planned for this behavior.
