PW0102 ILLEGAL PARAMETER (I-COMP.) The parameter for setting slope compensation is incorrect.
This alarm occurs in the following cases:
• When the number of pitch error compensation points on
the axis on which slope compensation is executed
exceeds 128 between the most negative side and most
positive side
• When the size relationship between the slope
compensation point Nos. is incorrect
• When the slope compensation point is not located
between the most negative side and most positive side of
pitch error compensation
• When the compensation per compensation point is too
small or too great.
Note
NOTE
1 Gradient compensation is enabled after the
reference position is established on the
compensation axis.
2 When the gradient compensation parameters are
set, turn the NC off then back on.
3 Parameters must satisfy the following conditions:
- The compensation amount at a compensation
point must be in the range of -128 to 127.
- Compensation points must satisfy the following
relationships: a ≤ b ≤ c ≤ d.
- Compensation points must be located between
the most distant compensation point in stored
pitch error compensation on the - side of each axis
and the most distant compensation point on the +
side. If all four points are equal to 0,
compensation is not performed.
4 To add the gradient compensation function option,
the stored pitch error compensation function option is
required.
The number of compensation points located between
the most distant compensation point on the + side of
each axis and the most distant compensation point
on the + side in stored pitch error compensation must
not exceed 128.
5 Gradient compensation is superimposed on the
stored pitch error compensation data.
