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
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‚ set the compensation amount in the division points
obtained by equally dividing the machine coordinates. (See Fig. 1. 1)
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.
