WINNC SINUMERIK 810 D / 840 D CONTROL ALARMS
Explanation: %1 = Channel number
%2 = Axis name, spindle number
After starting the reference point approach, the rising edge of the reduction cam must be reached within the section
defined in the MD 34030 REFP_MAX_CAM_DIST (phase 1 of referencing). (This error occurs only with
incremental encoders).
Reaction: Alarm display. Interface signals are set. NC Stop when alarm. NC Start disable.
Remedy: There are 3 possible causes of error:
1. The value entered in MD 34030 REFP_MAX_CAM_DIST is too small. Determine the maximum possible distance
from the beginning of reference motion up to the reduction cam and compare with the value in the MD:
REFP_MAX_CAM_DIST, increase the value in the MD if necessary.
2. The cam signal is not received by the PLC input module. Operate the reference point switch by hand and check
the input signal on the NC/PLC interface (route: switch!connector!cable! PLC input!user program).
3. The reference point switch is not operated by the cam. Check the vertical distance between reduction cam and
activating switch.
Clear alarm with RESET key. Restart part program.
20001 Channel %1 axis %2 cam signal missing
Explanation: %1 = Channel number
%2 = Axis name, spindle number
At the beginning of phase 2 of reference point approach, the signal from the reduction cam is no longer available.
Phase 2 of reference point approach begins when the axis remains stationary after deceleration to the reduction
cam. The axis then starts in the opposite direction in order to select the next zero marker of the measuring system
on leaving the reduction cam or approaching it again (negative/positive edge).
Reaction: Alarm display. Interface signals are set. NC Stop when alarm. NC Start disable.
Remedy: Check whether the deceleration path after the approach velocity is greater than the distance to reference point cam
- in which case the axis cannot stop until it is beyond the cam. Use longer cam or reduce the approach velocity in
machine data 34020 REFP_VELO_SEARCH_CAM. When the axis has stopped at the cam, it must be checked
whether the signal „DECELERATION REFERENCE POINT APPROACH“ is still available at the interface to the NCK
(DB 31 - 48, DBX 12.7).
• Hardware: Wire break? Short circuit?
• Software: User program?
Clear alarm with RESET key. Restart part program.
20002 Channel %1 axis %2 zero reference mark not found
Explanation: %1 = Channel number
%2 = Axis name, spindle number
The zero marker of the incremental encoder is not within a defined section. Phase 2 of reference point approach
ends when the zero marker of the encoder has been detected after the rising/falling edge of the PLC interface signal
„DECELERATION REFERENCE POINT APPROACH“ (DB 31 - 48, DBX 12.7) has given the trigger start. The
maximum distance between the trigger start and the zero marker that follows is defined in the machine data 34060
REFP_MAX_MARKER_DIST. The monitor prevents a zero marker signal from being overtraveled and the next
being evaluated as reference point signal. (Faulty cam adjustment or excessive delay by the PLC user program.)
Reaction: Alarm display. Interface signals are set. NC Stop when alarm. NC Start disable.
Remedy: Check the cam adjustment and make sure that the distance is sufficient between the end of the cam and the zero
marker signal that follows. The path must be greater than the axis can cover in the PLC cycle time. Increase the
machine data 34060 REFP_MAX_MARKER_DIST, but do not select a value greater than the distance between the
2 zero markers. This might result in the monitor being switched off.
Clear alarm with the RESET key. Restart part program.
20003Channel %1 axis %2 encoder error
Explanation: %1 = Channel number
%2 = Axis name, spindle number
In a measuring system with distance-coded reference marks, the distance between two adjacent markers has been
found to be more than twice the distance entered in the machine data 34300 ENC_REFP_MARKER_DIST. The
control issues the alarm after having made a second attempt in reverse direction with half the traversing velocity
and detecting that the distance is too large again.
Reaction: Alarm display. Interface signals are set. NC Stop when alarm. NC Start disable.
Remedy: Determine the distance between 2 odd reference point markers (reference point marker interval). This value (which
is 20.00 mm on Heidenhain scales) must be entered in the machine data 34300 ENC_REFP_MARKER_DIST.
Check the reference point track of the scale including the electronics for the evaluation.
Clear alarm with RESET key. Restart part program.
20004 Channel %1 axis %2 reference mark missing
Explanation: %1 = Channel number
%2 = Axis name, spindle number
In the distance-coded length measurement system two reference marks were not found within the defined
searching distance (axis-specific MD: 34060 REFP_MAX_MARKER_DIST). No reduction cam is required for
distance-coded scales (but an existing cam will be evaluated). The conventional direction key determines the
direction of search. The searching distance 34060 REFP_MAX_MARKER_DIST, within which the two reference
point markers are expected is counted commencing at the start point.
Reaction: Alarm display. Interface signals are set. NC Stop when alarm. NC Start disable.
Remedy: Determine the distance between 2 odd reference point markers (reference point marker interval). This value (which
