Please note the following when changing the parameter data:
S
Machine data
Machine data can always be modified. Once you have modified the ma-
chine data, the machine data have to be reactivated (for single command,
see Section 9.3.3).
S
Increments
Modifications can be made in all operating modes (even in “Incremental
relative” mode) during movement. The modifications of the increments
must always be complete before a new movement is started in “Incremen-
tal relative” mode. If this is not the case, the error message “incremental
dimensions do not exist” is output Cl. 2/No. 13.
S
Tool offset data
Modifications can be made in all operating modes and during movement.
If modifications are made during starting or at block transitions when the
tool compensation is active (internal access to offset values), the error
message “tool offset value does not exist” is output Cl.3/No.35.
S
Traversing programs
– Programs which are not selected can always be modified.
– If modifications are made to a preselected program, including the sub-
program, preselection of the program is canceled. You must then se-
lect the program again. A modification can be made to a program
when BL = 0 (start of program/end of program) and on Stop.
Delete block: Specify the program no. and the block no. in the “data
field”. The other data/bits must not be assigned.
Insert block: The block number does not exist in the selected program.
The contents should be entered in accordance with the
“block format”.
Modify block: The block with the corresponding block number is overwri-
ten with the contents in accordance with “block format”.
