Overview of Alarms
NCK alarms
21800 [Channel %1: ] Workpiece setpoint %2 reached
Parameters: %1 = Channel number
%2 = Workpiece setpoint
Definitions: This alarm is activated via MD27880 $MC_PART_COUNTER, bit 1: The number of counted work-
pieces ($AC_ACTUAL_PARTS or $AC_SPECIAL_PARTS) is equal or already greater than the pro-
grammed value for the number of required workpieces ($AC_REQUIRED_PARTS). At the same time,
the channel VDI signal "Workpiece setpoint reached" is output. The value for the number of counted
workpieces ($AC_ACTUAL_PARTS) is reset, while the value of $AC_SPECIAL_PARTS is retained.
Note:
The setpoint/actual comparisons of the workpieces are only made after an NC start
under the condition that $AC_REQUIRED_PARTS > 0. If $AC_REQUIRED_PARTS
has a negative value, all workpiece counts activated through MD27880 $MC_PART_COUNTER are
frozen at the values they have reached,
and the nominal/actual comparison is discontinued.
Reaction: NC not ready.
Interface signals are set.
Alarm display.
Remedy: No program interrupt. Delete alarm display.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22000 [Channel %1: ] Block %3 spindle %2 gear stage change not possible
Parameters: %1 = Channel number
%2 = Spindle number
%3 = Block number, label
Definitions: A gear stage change for the spindle will not be possible, if:
- thread cutting (G33, G34, G35) is active
- the spindle is active as master or slave spindle in a coupling
- the spindle is being positioned
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: The gear stage is to be set prior to the corresponding machining step.
If it is necessary, however, to change the gear stage within one of the above mentioned functions, this
function must be switched off for the time of the gear stage change. Thread cutting is deselected with
G1; synchronous spindle coupling is switched off with COUPOF; the spindle positioning operation is
exited with M3, M4 or M5.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
22005 [Channel %1: ] Spindle %2 selected gear stage %3 not installed
Parameters: %1 = Channel number
%2 = Spindle number
%3 = Gear stage
Definitions: The first gear stage data block is active. The required gear stage is not installed in the 1st gear stage
data block. The number of installed gear stages is configured in MD35090
$MA_NUM_GEAR_STEPS.
Examples for the occurrence of the alarm with 3 gear stages installed (MD35090
$MA_NUM_GEAR_STEPS = 3):
* ...DO M44 or DO 45 was programmed in synchronized action for the spindle concerned.
* ...DO M70 was programmed and MD35014 $MA_GEAR_STEP_USED_IN_AXISMODE was larger
than 3.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Modify part program: Only those valid gear stages can be entered which have also been installed
according to MD35090 $MA_NUM_GEAR_STEPS.
Limit M70 configuration (MD 35014 $MA_GEAR_STEP_USED_IN_AXISMODE) to MD35090
$MA_NUM_GEAR_STEPS.
