2-49

SINUMERIK 802D sl, Diagnostics Manual, 06/2009

Definitions: The motion planned for the axis violates the currently active working area limit.

The alarm is activated during the preparation of approach or rest blocks for REPOS.

This alarm is issued instead of alarm10733 if bit11 is not set in MD11411

$MN_ENABLE_ALARM_MASK.

Reaction: Local alarm reaction.

Interface signals are set.

Alarm display.

Remedy: Determine the cause of the offset from the initial or target position. The REPOS command is executed

at the end of an ASUB or system ASUB. See also cross reference from ASUBs.

Check the currently active work offset via the current frame.

Also check the external work offsets, overlaid movements ($AA_OFF), DRF and transformation com-

ponents.

Cancel NC program with NC reset.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10740 [Channel %1: ] Block %2 too many empty blocks in WAB programming

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: It is not allowed to program more blocks than specified by MD20202

$MC_WAB_MAXNUM_DUMMY_BLOCKS between the WAB block and the block determining the

approach and retraction tangent.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Modify part program.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

10741 [Channel %1: ] Block %2 direction reversal with WAB infeed motion

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: A safety distance which has been programmed is located perpendicular to the machining plane and

not between the start and end point of the WAB contour.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Modify part program.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

10742 [Channel %1: ] Block %2 WAB distance invalid or not programmed

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: Possible causes:

In a WAB block, the parameter DISR has not been specified or its value is less than or equal to 0.

During approach or retraction with circle and active tool radius, the radius of the internally generated

- WAB contour is negative. The internally generated WAB contour is a circle with a radius which, when

offset with the current offset radius (sum of tool radius and offset value OFFN), yields the tool center

point path with the programmed radius DISR.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Modify part program.
