Writing Traversing Programs
To execute the desired operations of the machine axis (sequence, position,
etc.) in “Automatic” mode, the FM 453 needs certain information. This in-
formation is programmed with “Parameterize FM 453” (traversing program
creation) in the form of a traversing program, based in principle on DIN
66025.
Each traversing program is stored under a program number.
A traversing program consists of not more than 100 traversing blocks.
The program number and traversing blocks are converted to an internal for-
mat (see Section 9.3.12), are stored in the appropriate data block, and are
transferred to the module. where they are administered.
The possible number of programs depends on the amount of memory avail-
able (max. 16 Kbytes) and on the length of the individual programs.
Program length in bytes: 110 + (20 x no. of traversing blocks)
Any program can be assigned a name (optional).
The program name may have up to 18 characters, and is saved with the pro-
gram.
Programs may be numbered from 1 to 199.
A traversing block contains all the data required to perform a machining step.
A program consists of several blocks. Each block number occurs only once,
and numbers are arranged in ascending order.
