- Compensation example
If, in the setting example given in the previous section, the machine
moves
from 0.0 to 40.0,
from 40.0 to -40.0, and
from -40.0 to 0.0
for a manual reference position return,
pitch error compensation pulses are output as follows:
Machine coordinate
0.0 5.0 15.0 25.0 35.0
40.0
Compensation pulse
--1-2+1+1+5
Machine
coordinate
35.0 25.0 15.0 5.0 -5.0 -15.0 -25.0 -35.0
-40.0
Compensation
pulse
-2 -1 +2 -1 +2 -1 +1 -1 -2
Machine coordinate
-35.0 -25.0 -15.0 -5.0 0.0
Compensation pulse
+1 -1 0 -1 -
When the travel direction changes from positive to negative at the
position of 40.0, the compensation for the reverse of the travel direction
is output.
A pulse of +5 is the result of the following calculation:
