21703
Channel %1 block %3 axis %2 touch probe not deflected, illegal edge
polarity
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
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.
Reaction:
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
Continuation:
Clear alarm with the RESET key. Restart part program
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].
Reaction:
Alarm display.
Remedy:
With $A_OUTA[..] = x no greater values can be programmed than permitted in the respective machine
data.
Program
Continuation:
Clear alarm with the Delete key or NC START.
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).
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. Shorten interpolation cycle (if at all
possible).
Program
Continuation:
Switch control OFF - ON.
