Optimize Acceleration - HEIDENHAIN TNC 415 Technical Manual

Optimize acceleration

If the maximum acceleration of the servo loop cannot be determined with the battery supply, the
acceleration can be optimized as follows:
Connect storage oscilloscope to
tachometer of servo-amplifier of X axis.
Enter following values for
position monitoring
MP1410: 0.5
MP1420: 30
Enter following program in
"PROGRAMMING AND EDITING"
operating mode:

Enter acceleration from MP1060.0
in MP 1060.1 to 1060.4. Traverse
axes Y, Z, IV and V with the
acceleration value found. Reduce
values as required.
Enter 0.7 to 0.9 times the
computed values as
acceleration in MP1060.
