Incremental dimension INC Variable
The axis in question is traversed by this amount when the direction key (+ or -) is pressed.

If the scale factor is selected with G51, all the following programmed axis values are altered
using the scale factor (see Programming Guide for detailed description).
The scale factor is programmed together with G51 in a block.
Start angle for thread

Active on
–
If a starting angle for thread cutting is entered, it is easy to produce a multiple thread. This
setting data can be altered via the user interface or by programming ”G92 A ...” in the part
program. The option ”Extended thread package” must be active for this function.
The last angle to be entered is saved after Power off.
Maximum number of predecoded blocks (as from SW 5)

Active
At once
The number of predecoded blocks can be limited by a channel-specific setting data.
0: Limitation is disabled, as many blocks are decoded as possible.
1 - approx. 3 500: The number of predecoded blocks is limited to a defined value. The
maximum value depends on the available memory and from the setting
in the flexible memory configuration. If the existing number of block
buffers is exceeded, as many blocks as possible are predecoded.
The minimum value is 2 here. If the value 1 is entered it is
automatically switched over to 2.
