SINUMERIK 802D sl, Diagnostics Manual, 06/2007Edition

Remedy: Check and correct positions in the NC program.

Please inform the authorized personnel/service department.

Machine data: 36100 POS_LIMIT_MINUS/36120 POS_LIMIT_MINUS2 and 36110

POS_LIMIT_PLUS/36130 POS_LIMIT_PLUS2 must be checked for the software limit switches.

Check the axis-specific interface signals: "2nd software limit switch plus/minus" (DB 31 -61, DBX 12.2

and 12.3) to see whether the 2nd software limit switch is selected.

Check currently active work offsets via the current frame.

Work offsets, overlaid movements ($AA_OFF), DRF and transformations components must also be

checked.

Program Con-

tinuation:

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

10723 Channel %1 block %5 axis %2 software limit switch %6 violated, residual

distance: %7 %3<ALUN>

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Unit of distance

%4 = Block number, label|number+string(+/-)|residual distance

Definitions: The motion planned for the axis violates the currently active software limit switch.

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

This alarm is issued instead of alarm 10721 if bit11=1 in machine data

$MN_ENABLE_ALARM_MASK. Alarm 10723 offers an expanded diagnostics option for the software

limit switch violation. The condition for activation is the presence of the ALUN* alarm file in the HMI.

See also the Diagnostics Guide for alarm 10721.

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.

Please inform the authorized Personnel/Service.

Check the machine data: 36100 POS_LIMIT_MINUS / 36120 POS_LIMIT_MINUS2 and 36110

POS_LIMIT_PLUS / 36130 POS_LIMIT_PLUS2 for the software limit switch.

Check the axis-specific interface signals "2nd software limit switch plus/minus" (DB31-61, DBX 12.2

and 12.3) to see whether the 2nd software limit switch is selected.

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 the NC program with NC reset.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10730 Channel %1 block %3 axis %2 working area limitation %4

Parameters: %1 = channel number

%2 = axis name, spindle number

%3 = block number, label

%4 = string (+ or -)

Definitions: This alarm is generated if it is determined during block preparation that the programmed path of the

axis will result in exceeding the working area limitation.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

Remedy: a)Check the NC program for correct position data.

b)Check zero offsets (current frame)

c)Correct work area limitation with G25 or

d)Correct work area limitation via setting data or

Deactivate working area limitation via SD 43410 WORKAREA_MINUS_ENABLE=FALSE

Program Con-

tinuation:

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