PARAMETER
(ST.COMP B)
Parameter related to straightness compensation B
have been erroneously specified.
Possible causes are as follows.
1. Invalid axis number have been assigned to move or
compensation axes.
2. The number of pitch-error compensation positions
between the maximum positive and maximum
negative positions exceeds 128.
3. Straightness compensation position numbers have
been assigned in order other than ascending order.
4. Straightness compensation positions could not be
located between the maximum positive and
maximum negative pitch-error compensation
positions.
5. The amount of compensation per compensation
position is too large or too small.
NOTE
1 The straightness compensation B 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 B, be sure to turn off the CNC power.
3 Set parameters for straightness compensation B according to the following conditions:
・ The compensation at a compensation position must be within the range –128 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 position can be set to 0 at a time. In this case, compensation is
not performed.
4 To add the straightness compensation B 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 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.
6 The straightness compensation B function can’t be used in the Power Mate i-MODEL D 2 PATH
control system.
