- 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))
