SINUMERIK 802D sl, Diagnostics Manual, 06/2007Edition

20082 Channel %1 block %2 coordinate system-specific working area limit %3

Parameters: %1 = Channel number

%2 = Axis number

%3 = "+" or "-"

Definitions: The displayed axis is operated as a "concurrent positioning axis", and the corresponding active coor-

dinate system-specific working area limitation for the axis is violated. No traversing movement.

With an additional message to alarm 20140, the axis is traversed as a command axis.

Reaction: Alarm display.

Remedy: - Specify smaller target position.

- Deactivate working area limitation.

- Set working area limitation differently.

- Retract axis with JOG.

Program Con-

tinuation:

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

20083 Channel %1 axis %2 programmed position lies behind the coordinate

system-specific working area limit %3

Parameters: %1 = Channel number

%2 = Axis number

%3 = "+" or "-"

Definitions: The axis is traversed as a reciprocating axis, and the target position (reversal position or end position)

is located behind the corresponding, valid, coordinate system-specific working area limitation. The

axis is not traversed.

Reaction: Local alarm reaction.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Specify smaller target position.

Deactivate working area limitation.

Set working area limitation differentially.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

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 continuation: Alarm display disappears

with alarm cause. No further operator action necessary.

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: The "Travel to fixed stop" function has been programmed with FXS[AX]=1 but the axis does not (yet)

support this. Check MD 37000 FIXED_STOP_MODE. The function is not available for simulated axes.

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

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

which the "Travel to fixed stop" function is activated.

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.
