MP1910 Monitor speed controller (drive monitoring)
Entry: 1 to 16 777 215 [counting steps]

MP1910.3 4th axis
MP1910.4 5th axis
The entry is axis-specific and made in counting steps. MP1910.x monitors the theoretically
calculated output voltage of the speed controller. If this voltage exceeds the limit specified in
MP1910.x the error message "Gross positioning error 3F" appears. This voltage is always limited
to ± 10 V at the output.
The input value for MP1910.x can therefore be calculated as follows:
MP 1910.x =
Ulimit
MP1920.x * 9.7 µV
The speed controller integrated in the control system is a PI controller. The P and I components of
the speed controller can be set in machine parameters MP1920.x and MP1940.x.
