Nck Computing Time Reduced, Start Is Not Allowed; Asub Start Declined; Executing Of Init Blocks Not Fully Completed; Block %2 Maximum Number Of Symbols Exceeded - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
16962 [Channel %1: ] NCK computing time reduced, start is not allowed.
Parameters: %1 = Channel number
Definitions: The computing time available to the NCK has been reduced, starts have therefore been locked. The computer perfor-
mance is inadequate for smooth program execution. The computing time of the NCK may have been reduced by the
HMI because of an HMI part program simulation.
Reaction: Alarm display.
Remedy: Wait for the simulation to end or press RESET in any channel.
Program Clear alarm with the Delete key or NC START.
Continuation:
16963 [Channel %1: ] ASUB start declined
Parameters: %1 = Channel number
Definitions: An external ASUB start fom the ABORTED program state has been declined for the following reasons:
- Bit 0 is not set in MD11602 $MN_ASUP_START_MASK
- ASUB priority has been set too low or MD11604 $MN_ASUP_START_PRIO_LEVEL has been set too high
Reaction: Alarm display.
Remedy: Correct the machine data or change the priority of the ASUB to be executed.
Program Clear alarm with the Delete key or NC START.
Continuation:
16964 [Channel %1: ] Executing of init blocks not fully completed
Parameters: %1 = Channel number
Definitions: Init blocks are processed during ramp-up; they ensure that the control is initialized correctly. The alarm is set if pro-
cessing could not be completed correctly (usually due to alarms which were already pending).
Reaction: Alarm display.
Remedy: Eliminate pending alarms.
Program Switch control OFF - ON.
Continuation:
17000 [Channel %1: ] Block %2 maximum number of symbols exceeded
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The maximum number of symbols defined by machine data MD28020 $MC_MM_NUM_LUD_NAMES_TOTAL has
been exceeded.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
- Modify machine data
- Reduce the number of symbols (variables, subroutines, parameters)
Program Clear alarm with the RESET key. Restart part program
