Enable protection zones
Signal(s) to channel (PLC → NCK)
Signal(s) updated: Cyclic
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.
No effect
This allows protection zones to be enabled:
● if the actual position is within a protection zone (alarm 2 present)
● if motion is to be started towards the protection zone limit (alarm 1 or 2
present)
Function Manual Basic Functions K1
Activate the program test
Signal(s) to channel (PLC → NCK)
Signal(s) updated: Cyclic
Axis disable is set internally for all axes (not spindles). Therefore the ma‐
chine axes do not move when a part program block or a part program is
being processed. The axis movements are simulated on the operator inter‐
face with changing axis position values. The axis position values for the
display are generated from the calculated setpoints.
Otherwise, the part program is executed normally.
The part program execution is not affected by the program test function.
IS "Program test selected"
IS "Program test active"
Function Manual Basic Functions K1
Activate skip block
Signal(s) to channel (PLC → NCK)
Signal(s) updated: Cyclic
Blocks marked in the part program with a slash (/) are skipped. If there is a
series of skip blocks, this signal is only active if it is present before decoding
of the first block of the series, ideally before "NC start".
The marked part program blocks are not skipped.
IS "Skip block selected"
