Error code 25 080 Axis %1 positioning monitoring Explanation %1 = Axis name, spindle number The axis of blocks in which “exact stop” is active must have reached the exact positioning window after the positioning time set in the axis-specific MD 36 020 POSITIONING_TIME. Exact stop coarse: MD 36 000 STOP_LIMIT_COARSE Exact stop fine: MD 36 010 STOP_LIMIT_FINE Response Channel not ready for operation. NC Start inhibited. NC Stop at alarm. The NC changes to follow-up mode. Alarm display. Interface signals are set. Remedy Check whether the exact stop limit (coarse and fine) correspondsto the dynamic possibilities of the axes; otherwise, increase the exact stop limit, if necessary, in conjunction with the positioning time defined in MD 36 020 POSITIONING_TIME. Check speed controller/position controller optimization; select gain as high as possible. Check setting of the loop-gain factor (KVfactor) (MD 32 200 POSCTRL_GAIN); increase if necessary. Program Press the RESET key to clear the alarm. Restart part program. continuation by Exact stop fine This criterion is used to monitor whether the actual position of the axis is away from the set position within a certain path distance. The size of the per permitted distance is stored in MD: STOP_ LIMIT_FINE (exact stop fine). Exact stop coarse The same scope of functions as exact stop fine, but the monitoring window is defined in MD: STOP_LIMIT_COARSE (exact stop coarse). In order to achieve a faster block change as with the exact stop fine criterion, the exact stop coarse window must be parametrized larger than the exact stop fine window.
