SINUMERIK 808D ADVANCED alarms
3.2 NCK alarms
Definitions: The gear stage required for axis mode has not been installed.
A gear stage has been configured in MD35014 $MA_GEAR_STEP_USED_IN_AXISMODE, in which the spindle is to
be in axis mode. This gear stage is checked whenever the spindle is switched into axis mode. The configured gear
stage is compared with the gear stage output by the PLC (NC/PLC interface signal DB380x DBX2000.0 - .2 (Actual
gear stage A through C)).
This alarm will be output if the gear stages are not the same.
Reaction: Interface signals are set.
Alarm display.
Remedy: Program M70 before the switch to axis mode. The gear stage configured in MD35014
$MA_GEAR_STEP_USED_IN_AXISMODE is then automatically loaded.
No gear stage change is required if the configured gear stage is aleady active. M40 remains active beyond the gear
stage change.
Consider MD20094 $MC_SPIND_RIGID_TAPPING_M_NR.
Program Clear alarm with the Delete key or NC START.
Continuation:
22024 [Channel %1: ] Block %2 Spindle %3 tapping: PLC signal 'invert M3/M4' changed after
%4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle
%4 = Value
Definitions: When loading a G331 block it was detected that the NC/PLC interface signal DB380x DBX2001.6 (invert M3/M4) had
changed during part program execution. An alarm was output to prevent a tool break. The current value of the NC/
PLC interface signal is displayed as parameter 4.
Reaction: Channel not ready.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: A change in the NC/PLC interface signal DB380x DBX2001.6 (invert M3/M4) during part program execution should be
avoided.
If MD35035 SPIND_FUNCTION_MASK bit 22 is set, the NC/PLC interface signal DB380x DBX2001.6 (invert M3/M4)
is then no longer evaluated during tapping with G331, G332. The alarm is no longer output. Notice! Setting bit 22
means a change in function.
Program Clear alarm with the RESET key. Restart part program
Continuation:
22040 [Channel %1: ] Block %3 spindle %2 is not referenced with zero marker
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: The current position is not referenced with the measuring system position although reference is made to it.
Reaction: Alarm display.
Remedy: Correct NC part program. Create the zero mark synchronization by positioning, by rotation (at least 1 revolution) in
speed control mode or G74 before switching on the alarm generating function.
If this has been intentionally programmed, the alarm can be suppressed in the cyclic check with position control
already enabled with following and leading spindle(s) by means of MD11410 $MN_SUPPRESS_ALARM_MASK bit21
= 1 or by CP programming with CPMALARM[FAx] bit10 = 1 (in which FAx = following spindle).
Program Clear alarm with the Delete key or NC START.
Continuation:
22050 [Channel %1: ] Block %3 spindle %2 no transition from speed control mode to position
control mode
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
