Channel %1: preceding block and current block %2 must be separated through an
executable block
%1 = Channel number
%2 = Block number
The language functions WAITMC, SETM, CLEARM and MSG must be packed in sepa-
rate NC blocks due to the language definition. To avoid velocity drops, these blocks are
attached to the next NC block internally in the NCK (for MSG only in path control mode,
for WAITMC to the previous NC block). For this reason, there must always be an execut-
able block (not a calculation block) between the NC blocks. An executable NC block
always includes e.g. travel movements, a help function, Stopre, dwell time etc.
- Correction block is reorganized.
- Interpreter stop
- Interface signals are set.
- Alarm display.
Program an executable NC block between the previous and the current NC block.
Example:
N10 SETM.
N15 STOPRE ; insert executable NC block.
N20 CLEARM.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 subprograms: action %2<ALNX> maximum nesting depth exceeded
%1 = Channel number
%2 = Action number/action name
Various actions can cause the current procedure to be interrupted. Depending on the
action, asynchronous subroutines are activated. These asynchronous subroutines can be
interrupted in the same manner as the user program. Unlimited nesting depth is not possi-
ble for asynchronous subroutines due to memory limitations.
Example: In the case of an approach block in a repositioning procedure do not interrupt
repeatedly, instead wait until processing is completed.
Possible actions are: mode change, SlashOn/Off, overstoring.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Initiate a block change and repeat the action.
Clear alarm with the Delete key or NC START.
Channel %1 conflict when activating user data type %2
%1 = Channel number
%2 = Data type
The "activate user data" function (PI service _N_SETUDT) modifies a data block (tool off-
set, settable zero offset or base frame) which is also written by the NC blocks in prepara-
tion.
In the event of a conflict, the value entered by the MMC is reset.
Parameter %2 specifies which data block is affected:
1: Active tool offset
2: Base frame
3: Active zero offset
- Alarm display.
Check the inputs on the MMC and repeat if necessary.
Clear alarm with the Delete key or NC START.
