SINUMERIK 802D sl, Diagnostics Manual, 06/2009

20073 [Channel %1: ] Axis %2 cannot be repositioned

Parameters: %1 = Channel number

%2 = Axis number

Definitions: The concurrent positioning axis cannot be positioned because it has already been restarted via the

VDI interface and is still active. No repositioning motion takes place and the motion initiated by the

VDI interface is not affected.

Reaction: Alarm display.

Remedy: None.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

20080 [Channel %1: ] Axis %2 no handwheel assigned for override

Parameters: %1 = Channel number

%2 = Axis number

Definitions: No handwheel has been assigned for this specified axis after handwheel overlay has been started in

automatic mode. If the axis identifier is missing in the alarm with active velocity overlay FD > 0, then

the 1st geometry axis has not been defined in the NC channel. In this case the block is executed with-

out handwheel control.

Reaction: Alarm display.

Remedy: If handwheel control is required, a handwheel must be activated.

Program Con-

tinuation:

Alarm display showing cause of alarm disappears. No further operator action necessary.

20085 [Channel %1: ] Contour handwheel: traverse direction or overtravel of

beginning of block not allowed

Parameters: %1 = Channel number

Definitions: Travel takes place on the path with the contour handwheel in the opposite direction to the programmed

travel direction and the starting point of the path has been reached at the start of the block.

Reaction: Alarm display.

Remedy: Turn the contour handwheel in the opposite direction.

Program Con-

tinuation:

Alarm display showing cause of alarm disappears. No further operator action necessary.

20090 Axis %1 travel to fixed stop not possible. Check programming and axis

data.

Parameters: %1 = Axis name, spindle number

Definitions: 1. The "Traverse against fixed stop" function has been programmed with FXS[AX]=1 but the axis does

not (yet) support this. Check MD37000 $MA_FIXED_STOP_MODE. This function is not available for

gantry axes and simulated axes.

2. On selection, no movement was programmed for axis AX. AX is a machine axis identifier.

3. It is always necessary to program a traversing movement in the selection block for the axis/spindle

for which the "Traverse against fixed stop" function is activated.

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: Please inform the authorized personnel/service department.

- Check the axis type.

- Check MD37000 $MA_FIXED_STOP_MODE.

- Is a machine axis movement missing in the approach block?

Program Con-

tinuation:

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