5.138.1 Monitoring for counter overflow
This function extension will be available from library V2.02!
If the machine parameters transferred to the FB via the AxisData input are changed afterwards (e.g.
the gearbox factors), this may cause a counter overflow when the speed value defined via C04286
is converted from the real unit to the internal unit.
The FB reports an internal counter overflow due to a changed measuring system by the value "-12"
at the dnState status output and activates a corresponding error message:
