THERMAL DISPLACEMENT

COMPENSATION AMOUNT
[Function]
During ball screw thermal expansion compensation, the compensation amount calculated based on
the "thermal expansion offset compensation amount" (R2302) and "thermal expansion max.
compensation amount" (R2303) is set in this register by the NC.
[Operation]
The "thermal expansion offset compensation amount" and the "thermal displacement max.
compensation amount" is set as a set for each axis in the R register.
The current compensation amount is set by the NC into the "thermal displacement compensate
amount" (R1600).
The thermal expansion compensation is invalid for the axis if the "thermal expansion offset
compensation amount" and "thermal expansion max. compensation amount" are set to 0.
These R registers are cleared to zero when the power is turned ON.

A unit half of the minimum command unit is the setting unit.
If the minimum command unit is 1µm and 100 is set, for example, the compensation amount will be
50µm.
