Detailed descriptions of interface signals
4.7 Channel-specific signals
Signal state 1 or edge
change 0 → 1
Instead of with the programmed feedrate (for G1, G2, G3, CIP, CT), the axis
moves with the dry run feedrate specified using SD 42100: DRY_RUN_FEED
if the dry run feedrate is greater than the one that has been programmed.
This interface signal is evaluated at NC start when the channel was in the
"Reset" state.
When selected using the PLC, the IS "activate dry run feedrate" should be
set from the PLC user program.
Signal state 0 or edge
change 1 → 0
The axis travels with the programmed feedrate.
Effective after reset state.
Application Testing a workpiece program with an increased feedrate.

Signal state 1 or edge
change 0 → 1
Channel-specific referencing is started with the IS "Activate referencing". The
control acknowledges a successful start with the IS "Referencing active".
Each machine axis assigned to the channel can be referenced with channel-
specific referencing (this is achieved internally in the control by simulating the
plus/minus traversing keys). Via the axis-specific MD 34110:
REFP_CYCLE_NR (axis sequence for channel-specific referencing) can be
used to define the sequence in which the machine axes are referenced. If all
of the axes entered in MD: REFP_CYCLE_NR have reached there reference
point, then IS "all axes referenced" (DB3300 DBX4.2) is set.
Application If the machine axes are to be referenced in a particular sequence, the
following options are available:
• The operator must observe the correct sequence when starting.
• The PLC must check the sequence when starting or define it itself.
• The function channel specific referencing is used.

Enable protection zones
Signal(s) to channel (PLC → NCK)
Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
When a positive edge of this signal appears, a protection zone is enabled
and the active alarm cleared. Then, motion can start in the same protection
zone.
As a result of the start of motion, the protection zone is enabled, the IS
"machine or channel-specific protection zone violated" is set, and the axis
starts to move.
The enable signal is not required if a motion is started that does not lead
into the enabled protection zone.
