Please inform the authorized personnel/service department. 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 34060
REFP_MAX_MARKER_DIST.
Check the reference point track of the scale including the electronics for the evaluation.
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 reference point approach aborted
%1 = Channel number
%2 = Axis name, spindle number
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 condi-
tions indicated under remedy has been fulfilled.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
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 referenc-
ing sequence. (When all axes with contents 1 have reached the reference point, then the
axes with contents 2 start, etc.).
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 reference point creep velocity not reached
%1 = Channel number
%2 = Axis name, spindle number
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 travers-
ing will be started once again automatically with phase 1. If the approach velocity is not
attained at the second attempt either, the referencing will be aborted with the alarm dis-
play.
Approach velocity: 34040 REFP_VELO_SEARCH_MARKER
Velocity tolerance: 35150 SPIND_DES_VELO_TOL.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
