(ii) Selected tool's compensation No.
The number set in the R registers, shown in the table below, are used as the tool length and
nose wear data compensation numbers for automatic calculation.

(Notes) 1. If the compensation No. is 0, the compensation amount will be calculated as
"0".
2. If the compensation No. exceeds the number of offset sets in the
specifications, the "E76 TOOL No. ERROR" error will occur.

If two axes (ex. +X, –Z) are moved simultaneously, it will not be clear which contact surface
was contacted, so the measurement will not be made. Note that the error "E78 AX UNMATCH
(TLM )" will occur and the movement will stop for safety purposes.
