Alarm and message
Number Message Description
PW1103 ILLEGAL PARAMETER (S-COMP.128) The parameter for setting 128 straightness compensation
points or the parameter compensation data is incorrect,
PW5046 ILLEGAL PARAMETER (S-COMP.) The parameter for setting straightness compensation is
incorrect.
Note
NOTE
1 The straightness compensation function can be used
after a moving axis and its compensation axis have
returned to the reference position.
2 After setting parameters for straightness
compensation, be sure to turn off the NC power.
3 Set parameters for straightness compensation
according to the following conditions:
- The compensation at a compensation position
must be within the range -127 to 127.
- Compensation positions must be set so that
"a≤b≤c≤d" is satisfied.
- Compensation positions must exist between the
compensation position with the largest positive
value and that with the largest negative value in the
stored pitch error compensation data for each axis.
Four compensation positions can be set to 0 at a
time. In this case, compensation is not performed.
4 To add the straightness compensation function
option, the stored pitch error compensation option is
needed.
In this case, the number of compensation positions of
each axis between the compensation position with the
largest positive value and that with the largest
negative value in the stored pitch error
compensation data must be equal to or less than 128.
5 Straightness compensation data is superposed on
stored pitch error compensation data and output.
Straightness compensation is performed at pitch error
compensation intervals.
6 Straightness compensation does not allow the moving
axis to be used as a compensation axis. To
implement such compensation, use gradient
compensation (see Subsection "Gradient
Compensation").
