Channel %1 block %3 axis %2 software limit switch %4
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
%4 = String ( + or - )
For the axis, the programmed path violates the currently valid software limit switch. The
alarm is activated when preparing the part program block.
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
Correct the NC program.
Please inform the authorized personnel/service department. Check the position of the
axis as specified in the part program.
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 zero offsets via the current frame.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %3 axis %2 software limit switch %4
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
%4 = String ( + or - )
For the axis, the planned motion violates the software limit switch. The alarm is activated
during the preparation of approach or rest blocks at REPOS.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
Check in the NC program and current positions.
Check the axis-specific interface signals "2nd software limit switch plus/minus" (DB31-61,
DBX 12.2 or 12.3) to see whether the 2nd software limit switch is selected.
Check currently active zero offset 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.
Clear alarm with the RESET key. Restart part program.
Channel %1 block %3 axis %2 working area limitation %4
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
%4 = String ( + or - )
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.
