Parameter
5.139.1 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 C04290
is converted from the real unit to the internal unit.
The FB causes a corresponding error message in case of an internal counter overflow due to a chan-
ged measuring system:
