Machine data list
All machine data of the FM 353 are listed in Table 5-4.
Notes to the machine data list:
K are configuration data; seeSection 9.3.3
E are settable machine data for alignment (start-up optimization) and technology,
seeSection 9.3.3
The units of measurement refer to the value representation in the machine data
DB.

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)
