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

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10720 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: For the axis, the programmed path violates the currently valid software limit switch. (The 2nd software

limit switch is selected with interface signal "2nd software limit switch Plus/Minus" in V 380x1000.2

and 0.3). The alarm is activated when preparing the part program block.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

Remedy: Check the position of the axis as specified in the part program.

Check MD 36110 POS_LIMIT_MINUS/MD 36130 POS_LIMIT_MINUS2 and MD 36100

POS_LIMIT_PLUS/MD 36120 POS_LIMIT_PLUS2 for the software limit switches.

Check the axis-specific interface signals: "2. Check whether 2nd software limit switch is selected with

software limit switch "Plus/Minus" (V 380x1000.2 and .3).

Check currently active zero offsets via the current frame.

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 planned motion violates the software limit switch for the axis. The alarm is activated during the

preparation of approach or rest blocks at REPOS.

Reaction: Local alarm reaction.

Interface signals are set.

Alarm display.

Remedy: Check in the NC program and current positions. Check whether 2nd software limit switch is selected

with axis-specific interface signal "2nd software limit switch Plus/Minus” (V 380x1000.2 and .3).

Check currently active zero offsets via the current frame.

Check the machine data for the software limit switch (36100 POS_LIMIT_MINUS / 36120

POS_LIMIT_MINUS2 or 36110 POS_LIMIT_PLUS / 36130 POS_LIMIT_PLUS2).

Interrupt the NC program via NC reset.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10722 Channel %1 block %5 axis %2 software limit switch %6 violated, residual

distance: %7 %3<ALUN> violated

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Unit of distance

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

Definitions: The path programmed for the axis violates the currently valid software limit switch. The alarm is acti-

vated when preparing the part program block.

This alarm is issued instead of alarm 10720 if bit 11=1 in the machine data

$MN_ENABLE_ALARM_MASK. Alarm 10722 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 diagnostics guide for alarm 10720.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.
