Geometry axis 1: Rapid traverse override

Signal flow

PLC → NC

Update

Cyclic

Signal state 1

When manually traversing the geometry axis using the traversing keys, when the interface

signal is set, rapid traverse velocity becomes active (MD32010).

Signal state 0

When manually traversing the geometry axis using the traversing keys, the entered JOG ve-

locity becomes active (SD41110 or MD32020).

Additional information

The signal is only active for continuous or incremental manual traversing in the JOG mode.

The signal is irrelevant:

• for reference point approach (JOG mode)

• in the AUTOMATIC and MDI modes

The rapid traverse velocity can be influenced using the rapid traverse override switch.

19.2 Interface signals - detailed description

DB21, ... DBX12.6 - 7

Geometry axis 1: traversing keys "Plus" / "Minus"

Additional information

There is a request signal for every traversing key and/or axis direction:

Bit 6

Traversing key "Minus" (for traversing in the negative axis direction)

Bit 7

Traversing key "Plus" (for traversing in the positive axis direction)

Depending on the active machine function, as well as the settings for jog and con-

tinuous operation (SD41050 and MD11300), different responses are initiated when

the signal changes:

1. Continuous manual travel in the jog mode

The geometry axis traverses in the direction concerned to the active limit switch

as long as the interface signal is set to 1.

2. Continuous manual travel in continuous operation

At the first edge change 0 →1, the geometry axis starts to traverse in the relevant

direction. This traversing movement still continues when the edge changes

from 1 → 0. Any new signal edge change 0 → 1 (same traversing direction!)

stops the traversing movement.

3. Incremental manual travel in the jog mode

With signal 1 the geometry axis starts to traverse at the set increment. If the

signal changes to the 0 state before the increment is traversed, then traversing

is interrupted. When the signal state changes to 1 again, traversing is continued.

The geometry axis can be stopped and started several times as described above

until it has traversed the complete increment.

4. Incremental manual travel in continuous operation

At the first edge change 0 → 1 the geometry axis starts to traverse at the set

increment. If another edge change 0 → 1 is performed with the same traverse

signal before the geometry axis has traversed the increment, the traversing

movement will be cancelled. The increment is no longer traversed to the end.

Note

• The interface signal is irrelevant in operating modes:

- AUTOMATIC

- MDI

• If both traversing signals ("plus" and "minus") are set at the same time there is no

traversing or the current traversing is aborted.

• In contrast to machine axes, for geometry axes, only one geometry axis can be

traversed at any one time using the traversing keys.

• Using DB21, ... DBX12.4, 16.4, 20.4 (geometry axes 1, 2, 3: Traversing key lock)

traversing using traversing keys can be locked.

• In the following cases, the geometry axis cannot be traversed in the JOG oper-

ating mode:

- The geometry axis is already being traversed via the axis-specific interface as

machine axis.

- If another geometry axis is already being traversed with the traversing keys.

Continuous manual travel

Incremental manual travel

In addition to five fixed increment sizes (default setting in MD11330: INC1, INC10, INC100,

INC1000 and INC10000), a variable increment size (INCvar) that can be set via the setting data

SD41010 is also available. The distance evaluation of one increment for fixed and variable

increment sizes is performed via the axis-specific machine data MD31090.

When pressing the "Plus" or "Minus" traversing key, or by rotating the electronic handwheel, the

geometry axis starts to traverse in the appropriate direction, corresponding to the number of

increments of the active machine function.

Continuous manual travel

For continuous manual travel, the plus and minus traversing keys are selected to move the

geometry axis continuously and the appropriate direction.

Notes

• If several requests are set simultaneously, no machine function becomes active.

• If a geometry axis is currently being traversed via a machine function, the movement is

aborted through deselection or change of the machine function.

Additional information

A tool assumes the "locked" state if the actual value of the active monitoring function (work-

piece count, tool life or wear) has reached a value of zero. If the tool is still being used, then it

remains in use (for machining) until the next tool change. After that the tool can no longer be

used.

Using the interface signal, it can be set that the NC does not take the "locked" state into account

when searching for a tool that can be used.

The interface signal is not active if the tool selection is realized using in it blocks (reset and start

Program state "interrupted"

Additional information

The signal indicates that the interrupted NC program can be continued with NC start (DB21, ...

DBX7.1 = 1).

For example, the "interrupted" state is assumed if, in the "stopped" state (DB21, ... DBX35.2 ==

1), the system changes from the AUTOMATIC or MDI mode into the JOG mode. After a subse-

quent operating mode change from JOG to AUTOMATIC or MDI, the NC program can be exe-

cuted again from the interruption point using an NC start (DB21, ... DBX7.1 = 1).

Program states:

• DB21, ... DBX35.4 (program state "aborted")

• DB21, ... DBX35.3 (program state "interrupted")

If two position measuring systems are connected to an axis, that would prevent an NC start,

then the active one must be referenced so that the axis is considered to have been referenced.

An NC Start command for the part program processing is only accepted when this signal is

present.

Axes that have to be referenced are axes, if:

Signal state 1

The interface signal indicates when the program progress is blocked by the presence of an

alarm.

This relates to all alarms generated by stop response:

• Stop on the path with deletion of the ready signal

• Axes are braked

• Immediate stop on the path

• Interpreter is stopped, IPO buffer is still being executed.

• No stop at end of block

Alarms with the following alarm response are also taken into account:

• NC start disable in this channel

• NC start disable in this channel, ASUB starts, where relevant, are permitted

For alarms with this response the interface signal is not set until an NC start has been triggered

and only if the alarm has not yet been acknowledged. In this case, the interface signal is not set

until NC start.

The interface signals are set if the start of an ASUB is refused because of an NC start disable in

this channel.

The interface signal is deleted as soon as alarm responses that activated the signal are no

longer active. This depends on the delete conditions of the alarms.

19.2 Interface signals - detailed description

DB21, ... DBX40.4 - 5

Geometry axis 1: traversing request "Plus" / "Minus"

Additional information

Depending on the mode selected, the traversing request is initiated in different ways:

• JOG mode

"Plus" or "Minus" traversing key

• REF mode

Traversing key that initiates traversing motion in the direction of the reference point.

• AUTOMATIC or MDI mode

A program block with a traversing operation is executed for a geometry axis.

There is a signal for each axis direction:

Bit 4

Traversing request "Minus" (for traversing in the negative axis direction)

Bit 5

Traversing key "Plus" (for traversing in the positive axis direction)

Corresponds with

DB21, ... DBX46.4 - 5 (geometry axis 2: traversing request "Plus" / "Minus")

DB21, ... DBX52.4 - 5 (geometry axis 3: traversing request "Plus" / "Minus")

DB21, ... DBX12.6 - 7 (geometry axis 1: traversing keys "Plus" / "Minus")

DB21, ... DBX16.6 - 7 (geometry axis 2: traversing keys "Plus" / "Minus")

DB21, ... DBX20.6 - 7 (geometry axis 3: traversing keys "Plus" / "Minus")

DB21, ... DBX40.6 - 7 (geometry axis 1: traversing command "Plus" / "Minus")

DB21, ... DBX46.6 - 7 (geometry axis 2: traversing command "Plus" / "Minus")

DB21, ... DBX52.6 - 7 (geometry axis 3: traversing command "Plus" / "Minus")

19.2.5.120

DB21, ... DBX40.6 - 7 (geometry axis 1: traversing command "Plus" / "Minus")

DB21, ... DBX40.6 - 7

Geometry axis 1: traversing command "Plus" / "Minus"

Signal flow

NC → PLC

Update

Cyclic

Signal state 1

There is a traversing request for the geometry axis or the geometry axis is traversing.

Signal state 0

There is not a traversing request for the geometry axis or the geometry axis is not traversing.

Additional information

Depending on the setting of MD17900, bit 0, the traversing command is already output if a

"Traversing request" is active (bit 0 = 0) or only if the axis is actually traversing (bit 0 = 1).

There is a signal for each axis direction:

Bit 6

Traversing command "Minus" (for traversing in the negative axis direction)

Bit 7

Traversing command "Plus" (for traversing in the positive axis direction)

Application example

Releasing the axis clamp when the traversing command is identified.

Note

For axes where clamping is not released until a drive command is detected, the continuous-

path mode (G64) is not possible.
