Remedy: - Modify part program.
- Check tool data.
- Check machine data.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
14745 Channel %1 block %2 centerless grinding not active
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: An attempt has been made to switch off the centerless grinding function even though it was not active.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
14750 Channel %1 block %2 too many auxiliary functions programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: More than 10 auxiliary functions have been programmed in an NC block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Check whether all auxiliary functions are necessary in one block - modal functions need not be
repeated. Create separate auxiliary function block or divide the auxiliary functions over several blocks.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
14751 Channel %1 block %2 resources for motion synchronous actions not
sufficient (code: %3)
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Identifier
Definitions: Processing of motion synchronous actions requires resources that are configured via the machine
data $MC_MM_IPO_BUFFER_SIZE, $MC_MM_NUM_BLOCKS_IN_PREP,
$MC_MM_NUM_SAFE_SYNC_ELEMENTS and $MC_MM_NUM_SYNC_ELEMENTS. If these
resources are insufficient for executing the part program, then this alarm is issued. Parameter %3
shows which resource has run out:
Increase identifier <= 2: $MC_MM_IPO_BUFFER_SIZE or
$MC_MM_NUM_BLOCKS_IN_PREP.
Increase identifier > 2: $MC_MM_NUM_SYNC_ELEMENTS,
$MC_MM_NUM_SAFE_SYNC_ELEMENTS.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Correct part program or increase resources.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
