NCK alarms

2-164

SINUMERIK 802D sl, Diagnostics Manual, 06/2009

- Check the mechanical components, e.g. has the stop broken away? Has the part to be clamped

given way?

- Position window for zero speed control too small (MD37020 $MA_FIXED_STOP_WINDOW_DEF)

(SD43520 $SA_FIXED_STOP_WINDOW). Default is 1 mm in each case.

Program Con-

tinuation:

Clear alarm with the RESET key in all channels of this mode group. Restart part program.

20094 Axis %1 function has been aborted

Parameters: %1 = Axis name, spindle number

Definitions: The function has been aborted. The possible reasons for this are:

- Because a pulse disable has occurred, the torque can no longer be provided.

- The PLC has removed the acknowledgments.

The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY

(channel not ready).

Reaction: Mode group not ready.

Channel not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Channel not ready.

Remedy: Check whether

- there is a pulse disable from the infeed/regenerative-feedback unit or from the PLC?

- the acknowledgement bits have been deleted by the PLC even though NCK has not requested dese-

lection?

Program Con-

tinuation:

Clear alarm with the RESET key in all channels of this mode group. Restart part program.

20141 [Channel %1: ] Motion synchronous action: illegal axis type

Parameters: %1 = Channel number

Definitions: The requested command is not permissible in the current axis status for the command axis or spindle.

This alarm occurs with command axes (POS, MOV), spindle commands from motion synchronous

actions (M3/M4/M5, SPOS), coupled motion (TRAILON, TRAILOF) and lead value coupling (LEA-

DON, LEADOF).

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: First stop the axis or deactivate the coupling, then select a new status.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

21550 [Channel %1: ] Axis %2 Travel from hardware limit switch not possible.

Reason: %3

Parameters: %1 = Channel number

%2 = Axis name

%3 = Cause

Definitions: It has been tried to retract a following axis of an axis coupling or an output axis of a transformation

through the master axis or input axis of a transformation. This is not permitted in the current situation.

Possible reasons:

1 No permissible direction of retraction

2 Coupling not synchronous

3 Retraction not permitted for the active coupling

4 Reserved

5 Retraction not permitted for the active transformation

Reaction: NC Start disable in this channel.

Alarm display.

Remedy: Remedy for error cause:

1 Define another travel direction

2 Deactivate the coupling and travel the axis/axes separately

3 Deactivate the coupling and travel the axis/axes separately
