A request was initiated for a "Mode group reset".
Responses:
• In all channels of the mode group, a "channel reset" is initiated in the control system
corresponding to DB21, ... DBX 7.7 = 1.
• All the channels are then in the channel state "reset" (DB21, ... DBX35.7 == 1)
• All active NC programs are then in the "canceled" program state (DB21, ... DBX35.4 == 1)
• All traversing axes and spindles are decelerated without contour violation to zero speed
according to their acceleration curves.
• The channel-specific reset positions become active.
• All alarms of the mode group are cleared - with the exception of power on alarms.
Edge change 1 → 0
Reset of the last request for a "Mode group reset".
Starting at this time, a new "Mode group reset" can be requested.
Further information
Special case
If an alarm resets the interface signal DB11 DBX6.3 (mode group ready), all channels of the
mode group are no longer in the "reset" channel state. In order that the mode of the mode
group can be switched over, initially, a "Mode group reset" must be initiated using DB11
DBX0.7.
Note
Before a new action can be requested in a channel of the mode group from the PLC user
program after a mode group reset (e.g. NC start or axis interchange), the system must first wait
for either the mode group state "All channels of the mode group in the reset state" (DB11
DBX6.7 == 1) - or the channel state "Reset" (DB21, ... DBX35.7 == 1) of the channel involved.

Additional information
Precise retracing of contours is possible on all programmed contours comprising straight and
circular elements. During retracing, other contour elements such as splines or automatically
inserted non-linear contour elements (circle, parable, etc. e.g. through tool radius compensa-
tion) are mapped as straight lines between the start and end points of the corresponding
contour element, thereby preventing precise retracing of contours.
The main RESU program (CC_RESU.MPF) is generated from the logged traversing blocks of the
RESU internal block buffer, so corresponding to the interface signal, the next time that the NC
starts, the contour can be traversed either backward or forward.

Additional information
The interface signal suppresses the fast "Initiate stroke" signal. This allows the part program to
be processed without initiating a punching operation (dry run). With active path segmenta-
tion, the axes traverse in the "Stop and go" mode.

The NC responds to this interface signal by immediately stopping motion. An alarm is output
if motion or another action is to be interrupted due to this signal.
In physical terms, the interface signal is identical to the fast signal "Stroke active" for the NC, i.e.
the system is wired in such a way that the two signals are taken to the same NC input via an AND
gate.

Additional information
This signal enables a single stroke to be initiated at the 2nd punch interface in manual mode.
In principle, this is possible in every operating mode, assuming that the axes do not move. The
signal is ignored if the axes are moved during the manual stroke initiation. During the stroke,
the axes are inhibited, i.e. they can only be moved again after the "Stroke initiation active"
signal has been withdrawn.

Additional information
• The interface signal is active for all of the geometry, synchronized and positioning axes
traversing in the channel.
• If the interface signal is set while traversing an axis, then the axis is braked down to stand-
still along its braking characteristic. For geometry axes, the axes are braked so that they
follow the contour.
• After the interface signal has been reset, traversing motion that was stopped is continued.
• The position control is retained and the following error is eliminated.
• If the interface signal is set, and a request is issued to traverse an axis, then the axis is not
traversed. However, the traverse request is kept. When the interface signal is reset, the
traverse request is immediately executed, i.e. the axis is traversed.
• The interface signal is active in all modes.

Delete distance-to-go (channel-specific)
Edge change 0 → 1
Delete distance-to-go (channel-specific) is requested.
Geometry axes
For a rising edge of the signal, the geometry axes currently traversing in the block are brought
to a standstill along a braking ramp and then the distance-to-go is deleted. Any remaining
following error is still corrected. The next traversing block is then loaded.
Path axes
"Delete distance-to-go" for path axes acts only in the AUTOMATIC mode.
Note
"Delete distance-to-go" causes the next traversing block to be prepared with the new positions.
After a "Delete distance-to-go", the geometry axes thus follow a different contour to the one
originally programmed in the NC program.
Traversal to absolute positions (G90) in the block after "Delete distance-to-go" causes at least
exact approach to the block end position. For incremental traversing (G91), the position speci-
fied in the NC program is not approached in the following block.

Note
Deactivating the protection zone is only active if it was preactivated via an NC program and was
activated via the interface signal.

Note
At any one time, an axis can only be assigned to one handwheel. If, for bit coding, several
interface signals are set simultaneously, then the following priority applies: "Handwheel 1"
before "Handwheel 2" before "Handwheel 3".

Signal state 0
Feedrate disable for geometry axis is not active.
Additional information
• If the interface signal is set while traversing a geometry axis, then the geometry axis is
braked down to standstill along its braking characteristic.
• After the interface signal has been reset, traversing motion that was stopped is continued.
• The position control is retained and the following error is eliminated.
• If the interface signal is set, and a request is issued to traverse an axis, then the axis is not
traversed. However, the traverse request is kept. When the interface signal is reset, the
traverse request is immediately executed, i.e. the axis is traversed.
• The interface signal is only active in the JOG mode.
