9. Machine Error Compensation
9.1 Function Outline
Machine error compensation includes two independent functions: memorized pitch error compensation
and memorized relative position compensation.
(1) Memorized pitch error compensation
According to the specified parameters‚ this method compensates an axis feed error caused by a
ball screw pitch error‚ etc.
With the reference point defined as the base‚ as shown in the following figure, set the
compensation amount in the division points obtained by equally dividing the machine coordinates.
The compensation amount can be set by either the absolute or incremental system.
Select the desired method with the "#4000 Pinc". Machine position is compensated between
division points n and n+1 as much as compensation amount between them by linear
approximation.
Relationship between the compensation amount and machine position
