TNC 406/TNC 306 1 Machine axes 4-11
An extra linear axis is designated by the letter U, V or W. The correlation with the principle axes
and the direction of travel are also standardized in ISO 841.

1.2.1 Assignment
The encoder inputs X1 to X6 and the analog outputs, Output 1 to Output 4 (on connector X8) can be
assigned to the individual axes. The assignment is determined by the machine parameters MP110
and MP120.

Entry: 0 = encoder input X1
1 = encoder input X2
2 = encoder input X3
3 = encoder input X4
4 = encoder input X5 *
5 = encoder input X6
