Bit 3 Bit 3=1 Extended overstore enabled. Only checked if extended overstore is
selected.
Bit 2 Bit 2=1 Jerk-controlled interpolator active
Bit 2=0 Standard interpolator active (default setting)
Bit 0 Bit 0=1 Reference point synchronization
By selecting the function G74 you can approach the reference point in a
programmed axis in a program. The function works in a similar way to the
reference point approach in the reference point mode. You can only select
this function in AUTOMATIC and MDA modes for one axis at a time.

Bit 4 Bit 4=1 Storing PLC alarm texts (PCF) in the NC part program memory
The alarm texts are stored in the NC part program memory in the same way
as in an ASCII file. The block numbers in this alarm text program correspond
to the alarm number to which the text is allocated. This file can be read in and
out via the MMC/computer link and can be edited, deleted, renamed and
copied within the possibilities offered by part program processing with certain
restrictions regarding start-up and password.
If available, the alarm texts are taken from the program, otherwise the display
submodules search for the alarm text in the UMS.
Bit 3 Bit 3=1 R parameter extension
This function gives you more R parameters.
R parameters Basic version Expansion
Channel-specific R00 - R599 R600 - R699
Central R700 - R899 R1000 - R1299
This bit is activated when the softkey "Format R parameters" is pressed in
initial clear mode.
