SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
Channel %1 command axis %2: rotation of axis container already enabled
%1 = Channel number
%2 = Axis
The synchronized action instruction is not allowed on a spindle enabled for the axis con-
tainer rotation. The alarm only occurs if the spindle is handed to another NCU.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Initiate the synchronized action instruction before the axis container rotation enable or
after the end of the rotation (depending on the application).
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 command axis cannot be started as it is controlled by the PLC
%1 = Channel number
%2 = Axis name, spindle number
An attempt has been made to start a command axis by means of a block-related or modal
synchronous action. This start is not possible as the axis is controlled by the PLC.
- Alarm display.
End control of the axis by the PLC and therefore return it to the channel or start the com-
mand axis with a static synchronous action.
Clear alarm with the Delete key or NC START.
Channel %1 block %2 motion synchronous action: system variable access not pos-
sible
%1 = Channel number
%2 = Block number
When using system variables, it is assumed that a read/write operation can access the
required data successfully. In accesses to encoder actual values or digital I/Os, the result
depends on the availability of the corresponding hardware components. If an access
within synchronized actions does not return a valid value, alarm 20144 is output. Outside
synchronized actions, such a read/write access causes block execution to be interrupted
until the result is available. Block execution is subsequently continued.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Before reading/writing system variables, ensure that it is possible to access the required
hardware components.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 motion synchronous action: arithmetic error
%1 = Channel number
%2 = Block number
In calculating an arithmetic expression for a motion synchronous action, an overflow has
occurred (e.g. division by zero).
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
