If bit DB3000 DBX1.6 is not set and bit DB3000 DBX1.7 is set, then it is
single block type A.
(If DB3000 DBX1.6 and DB3000 DBX1.7 are not set, it is impossible to
determine which single block type is required. The control then assumes: No
single block across mode groups).
Single block type A
Single block type A
Signal(s) updated:
DB3000 DBX1.7 set and DB3000 DBX1.6 not set: Response across modes
•
Channel is stopped.
•
Channel receives a start command.
•
Channel KS stops at the end of the block.
(If DB3000 DBX1.6 and DB3000 DBX1.7 are set simultaneously, it is
impossible to determine which single block type is required. The control then
assumes: No single block access across modes).
If DB3000 DBX1.7 is not set and DB3000 DBX1.6 is set, then it is single
block type B.
(If DB3000 DBX1.6 and DB3000 DBX1.7 are not set, it is impossible to
determine which single block type is required. The control then assumes: No
single block access across modes).

Machine function 1 INC, 10 INC, 100 INC, 1000 INC, 10000 INC, var. INC,
continuous
Signal(s) to modes (PLC → NCK)
Signal(s) updated: Cyclic
The input range is only used if IS "INC inputs active in the mode area"
(DB2600 DBX1.0) is set. These signals are valid for all axes and geometry
axes.
With the IS "INC..." it is defined by how many increments the axis moves
when actuating the traversing key or when rotating the handwheel for each
grid position. In this case, the JOG mode must be active. For "var. INC", the
value generally applies in SD41010 JOG_VAR_INCR_SIZE.
For "continuous" the associated axis can be traversed with the plus or minus
traversing key by keeping the traversing key pressed.
As soon as the selected machine function becomes active, this is signaled to
the PLC interface (IS "Active machine function 1 INC; ..." ). If several
machine function signals (1 INC, INC... or "Continuous traversing") are
selected at the interface simultaneously, then no machine function is
activated by the control.
Note:
The input IS "INC..." or "continuous" to change an active machine function
must be present for at least one PLC cycle. A steady-state signal is not
required.
