Overview of Alarms
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Change synchronous action.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
20149
Channel %1 block %2 motion synchronous action: illegal index
Parameters: %1 = Channel number
%2 = Block number
Definitions: An invalid index was used for access to a variable in motion synchronous action.
Example: ... DO $R[$AC_MARKER[1]] = 100
This error occurs if the value of marker 1 is greater than the maximum permissible R
parameter number.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Use a valid index.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
20150
Channel %1 tool management: PLC terminates interrupted command
Parameters: %1 = Channel number
Definitions: Indication that the PLC has terminated an interrupted command (with alarm output) from
the tool management - tool change.
Reactions: - Interface signals are set.
- Alarm display.
Remedy: For information only.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
20160
Channel %1 tool management: PLC can terminate only incorrectly aborted com-
mands
Parameters: %1 = Channel number
Definitions: Indication that the PLC wanted to interrupt an active command from the tool management
(tool change); or that there is no command active for abort. NCK refuses because the
channel status is either 'active' (abort is then not allowed), or 'reset' (then there is nothing
to abort).
Reactions: - Interface signals are set.
- Alarm display.
Remedy: For information only.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
20170
Channel %1 machine data $AC_FIFO invalid
Parameters: %1 = Channel number
Definitions: The structure of the FIFO variable $AC_FIFO - $AC_FIFO10 determined by the machine
data $MC_NUM_AC_FIFO, $MC_START_AC_FIFO, $MC_LEN_AC_FIFO and
$MC_MODE_AC_FIFO cannot be stored in the R parameter field defined in
$MC_MM_NUM_R_PARAM.
