4.20 PITCH ERROR COMPENSATION PARAMETERS (DATA NO.
5420 AND LATER)
5420 Number of pitch error compensation point of reference position for each axis
NOTE
After this parameter has been set, the power must be
off turned off then back on for the setting to become
effective.
[Input type] Parameter input
[Data type] Integeraxis
[Valid data range] From 0 through 1279 or from 0 through 3071 depending on the
number of controlled axes is less than or equal to 10 or greater than
10, respectively.
Set the number of the pitch error compensation point corresponding to
the reference position for each axis.
In rotation-axis pitch error compensation, a compensation point
number is basically set with the 0-degree point (machine zero point)
set as the reference position. If the reference position is not located at
the 0-degree point (machine zero point) , set parameters as follows:
- Set the parameter (No. 5424) specifying the interval between
pitch error compensation points so that the reference position is
an integral multiple of the interval away from the 0-degree point
(machine zero point)
- Set the parameter (No. 5422) specifying the number of the
farthest compensation point in the positive direction so that it
specifies the 360-degree (= 0-degree) point.
- Set the parameter (No. 5425) specifying angular displacement
per rotation to 360 degrees.
5421 Number of pitch error compensation point with the largest negative value for
each axis
NOTE
After this parameter has been set, the power must be off
turned off then back on for the setting to become
effective.
