- Compensation example
If, in the setting example given in the previous section, the machine
moves
0.0 to 40.0,
40.0 to -40.0, and
-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.
pulse of -5 is the result of the following calculation:
-5 = (-4) – (+1)
Pitch error associated with the positive-direction
absolute value at the position of 40.0
Pitch error associated with the negative-direction
absolute value at the position of 40.0
When the travel direction changes from negative to positive at the
position of -40.0, the compensation for the reverse of the travel
direction is output.
pulse of +2 is the result of the following calculation:
+2 = (-1)-(-3)
Pitch error associated with the negative-direction
absolute value at the position of -40.0
Pitch error associated with the positive-direction
absolute value at the position of -40.0
