Rapid traverse
Connect storage oscilloscope to tachometer
of the servo-amplifier of X axis.
Enter following program in

Press machine START button in the
"PROGRAM RUN/SINGLE BLOCK"
operating modes. Machine runs.
Does the tacho signal show overshoot?
U [V]
t [s]
Reduce multiplication factor
MP1820 in steps until overshoot
can no longer be detected.
Characteristic kink
not required.
Yes No
Repeat adjustment for axes Y, Z and IV.
1) Program the traverse paths for the axis concerned as large as possible.
The worst axis determines the entry value for MP 1820.
