SINUMERIK 802D sl, Diagnostics Manual, 06/2009

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 MD34060

$MA_REFP_MAX_MARKER_DIST.

Check the reference point track of the scale including the electronics for the evaluation.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

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 the value 1 has been set in

MD34000 $MA_REFP_CAM_IS_ACTIV (reference cams) and one of the conditions stated in the rem-

edy 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 termina-

tion:

- Servo enable missing: NC/PLC interface signal V380x 0002.1 (Servo enable)

- Measuring system switchover: NC/PLC interface signal V380x 0001.5 / 1.6 (Position measuring sys-

tem 1/2)

- Traversing key + or - missing: NC/PLC interface signal V380x 0004.7 / 4.6 (Traversing keys

plus/minus)

- Feed override = 0

- The feed disable is active

- Exact stop not reached within MD36020 $MA_POSITIONING_TIME.

The axis-specific MD34110 $MA_REFP_CYCLE_NR determines which axes are involved in the

channel-specific referencing.

ValueMeaning

-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 con-

tents 2 start, etc.).

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

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 refer-

ence 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. Phase 1 is therefore con-

sidered as being already concluded and will not be started.)

Phase 2 has been interrupted (this time before the cam) and the reference point approach will be

started once again automatically with phase 1. If the approach velocity is not reached at the 2nd

attempt either, referencing will be stopped and the alarm displayed.

Approach velocity: MD34040 $MA_REFP_VELO_SEARCH_MARKER

Velocity tolerance: MD35150 $MA_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 MD34040 $MA_REFP_VELO_SEARCH_MARKER and/or

increase the MD for the velocity tolerance MD35150 $MA_SPIND_DES_VELO_TOL.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program
