Overview of Alarms
Definitions: The selected probe is not (!) deflected and therefore cannot record any measured value
from the deflected to the non-deflected state.
Measurement level 2 (MEAWA, MEASA, MEAC)
The degree of deflection of the probe at the start of the measurement task is identical to
the first programmed measurement signal edge. The test is only performed in mode 2.
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Check probe
• Check start positioning for measuring
• Check program
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21740
Output value at analog output no. %1 has been limited
Parameters: %1 = No. of output
Definitions: The value range of the analog output n is limited by machine data 10330
FASTIO_ANA_OUTPUT_WEIGHT[n].
Reactions: - Alarm display.
Remedy: With $A_OUTA[..] = x no greater values can be programmed than permitted in the
respective machine data.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
21750
Error during output of cam signals via timer
Definitions: The signal output activated by the MD 10480 SW_CAM_TIMER_FASTOUT_MASK via
the hardware timer (independent of the clock grid) did not work. Cause: interpolation cycle
is greater than 15 ms.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - 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. Shorten interpolation cycle (if
at all possible).
Program Con- Switch control OFF - ON.
tinuation:
21760
Channel %1 block %2 too many auxiliary functions programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The number of programmed auxiliary functions has exceeded the maximum permissible
amount. This alarm can occur in conjunction with motion synchronous actions: The maxi-
mum number of auxiliary functions must not be exceeded in motion block and motion syn-
chronous actions.
Reactions: - Interpreter stop
