CAUTION
- Compensation value range
Compensation values can be set within the range
from -7 x compensation magnification (detection unit)
to +7 x compensation magnification (detection unit).
The compensation magnification can be set for each
axis within the range from 0 to 100 in parameter
5423.
- Intervals of compensation positions
The pitch error compensation positions are arranged
with equally spaced. Set the space between two
adjacent positions for each axis to the parameter (No.
5424).
- Pitch error compensation of the rotary axis
For the rotating axis, the interval between the pitch
error compensation positions shall be set to one per
integer of the amount of movement (normally 360
deg) per rotation. The sum of all pitch error
compensation amounts per rotation must be made to
0. Also, set the same compensation value to a
position and the same position with one rotation.
- Conditions where pitch error compensation is not
performed
Note that the pitch error is not compensated in the
following cases:
- When the machine is not returned to the reference
position after turning on the power. This excludes
the case where an absolute position detector is
employed.
- If the interval between the pitch error compensation
positions is 0.
- If the compensation position Nos. on the positive or
negative direction do not fall within the range of 0 to
[128 x (number of control axes)-1].
- If the compensation position Nos. do not conform to
the following relationship:
Negative side ≤ Reference position < Positive side
(Except when, in rotation-axis pitch error
compensation, the number of the farthest pitch
error compensation point in the negative direction is
assigned to a compensation point positioned next
to the 0-degree point in the positive direction if the
reference position is at 0 degrees (machine zero
point))
