Sinumerik Alarm 25080 Axis %1 positioning monitoring
Parameters:
%1 = Axis name, spindle number
Definitions:
For blocks in which “exact stop” is effective, the axis must have reached the exact stop window after the positioning time given in the axis-specific MD 36020 POSITIONING_TIME. Exact stop coarse: MD 36000 STOP_LIMIT_COARSE Exact stop fine: MD 36010 STOP_LIMIT_FINE The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– Mode group not ready.
– Channel not ready.
– If the axis is a single axis when this alarm is triggered, the alarm is only effective for this axis (not effective for e.g. the channel or mode group)
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.
Remedy:
Please inform the authorized personnel/service department. Check whether the exact stop limits (course and fine) correspond to the dynamic possibilities of the axis, otherwise increase them, if necessary in connection with the positioning time set in MD 36020 POSITIONING_TIME. Check speed controller/position controller optimization; select highest possible gains. Check setting of Kv factor (MD 32200 POSCTRL_GAIN) and increase if necessary.
Program Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
