1) The variable axis name is implemented as an axis letter (X, Y, Z, ...) with an address extension (1...9).
Permissible characters: X, Y, Z, A, B, C, U, V, W, Q, E, 1...9 e.g.: “X”, “X1”
2) see Dependencies
3) The axis name is in bytes 3 and 4 (bytes 1 and 2 give the character length specification)
