NCK alarms

2-48

SINUMERIK 802D sl, Diagnostics Manual, 06/2009

Check the axis-specific interface signals: V380x 1000.3 / .2 (2nd software limit switch plus/minus) to

see whether the 2nd software limit switch is selected.

Check the currently active work offsets via the current frame.

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

checked.

Program Con-

tinuation:

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

10721 [Channel %1: ] Block %3 axis %2 software limit switch %4

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Block number, label

%4 = String ( + or - )

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

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

Depending on MD11411 $MN_ENABLE_ALARM_MASK, bit11=0 this alarm is output instead of alarm

10723. If this MD11411 $MN_ENABLE_ALARM_MASK, bit11 is set in this machine data

$MN_ENABLE_ALARM_MASK, an expanded diagnostics option is offered 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 Manual for alarm 10723.

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 axis-specific NC/PLC interface signals V380x 1000.3 / .2 (2nd software limit switch

plus/minus) 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 violates the working area limitation.

If bit 11=0 in machine data MD11411$MN_ENABLE_ALARM_MASK, this alarm is issued instead of

alarm 10732. If bit 11 is set in machine dataMD11411 $MN_ENABLE_ALARM_MASK, an expanded

diagnostics option is offered for the software limit switch violation. The condition for activation is the

presence of the ALUN* alarm file in the HMI.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

Remedy: a) Check NC program for correct positional data and, if necessary, make corrections.

b) Check zero offsets (current frame)

c) Correct working area limitation via G25/G26, or

d) Correct working area limitation via setting data, or

e) Deactivate working area limitation via setting data 43410 WORKAREA_MINUS_ENABLE=FALSE

Program Con-

tinuation:

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

10731 [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 - )

1 2 ... 43 44 45 46 47 48 49 50 51 52 53 ... 339 340
