20005 Channel %1 axis %2 reference point approach aborted
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: Referencing could not be completed for all stated axes (e.g., abort caused by missing servo enable,
measuring system switchover, release of direction key, etc.).
In distance-coded measuring systems, the alarm will also be displayed, if value 1 has been set in MD
34000 REFP_CAM_IS_ACTIV (reference cams) and one of the conditions indicated under remedy
has been fulfilled.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Check the possible reasons for
termination:
- Servo enable missing (DB 31 - 48, DBX 2.1)
- Measuring system switchover (DB 31 - 48, DBX 1.5 and DBX 1.6)
- Traversing key + or - missing (DB 31 - 48, DBX 4.6 and DBX 4.7)
- Feed override = 0
- The feed disable is active
The axis-specific MD 34110 REFP_CYCLE_NR determines which axes are involved in the channel-
specific referencing.
-1: No channel-specific referencing, NC Start without referencing.
0: No channel-specific referencing, NC Start with referencing.
1-8: Channel-specific referencing. The number entered here corresponds to the referencing
sequence. (When all axes with contents 1 have reached the reference point, then the axes with
contents 2 start, etc.).
Program Clear alarm with the RESET key. Restart part program
Continuation:
20006 Channel %1 axis %2 reference point creep velocity not reached
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: In phase 2 of reference point approach (wait for zero mark), the cam end was reached but the
reference point approach velocity was not within the tolerance window. (This can occur when the axis
is already at the end of the cam at the beginning of reference point approach. This means that phase
1 has already been concluded and will not be started.)
Phase 2 has been interrupted (this time before the cam) and the reference point traversing will be
started once again automatically with phase 1. If the approach velocity is not attained at the 2nd
attempt either, the referencing will be aborted with the alarm display.
Approach velocity: 34040 REFP_VELO_SEARCH_MARKER
Velocity tolerance: 35150 SPIND_DES_VELO_TOL.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Reduce the MD for the approach velocity
34040 REFP_VELO_SEARCH_MARKER and/or increase the MD for the velocity tolerance 35150
SPIND_DES_VELO_TOL.
Program Clear alarm with the RESET key. Restart part program
