Sinumerik Alarm 20005 Channel %1 axis %2 reference point approach aborted
%1 = Channel number
%2 = Axis name, spindle number
Channel-specific referencing could not be completed for all stated axes (e.g., abort caused by missing servo enable, measuring system switchover, release of direction key, etc.).
– NC Start disable in this channel.
– Interface signals are set.
– Alarm display.
– NC Stop on alarm.
– 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)
Please inform the authorized personnel/service department. Check the possible reasons for termination: • Servo enable missing (DB 31 – 48, DBX 2.1) • Measuring system switchover (DB 31 – 48, DBX 1.5 and DBX 1.6) • Traversing key + or missing (DB 31 – 48, DBX 4.6 and DBX 4.7) • Feed override = 0 • The feed disable is active The axis-specific MD 34110 REFP_CYCLE_NR determines which axes are involved in the channel-specific referencing. -1: No channel-specific referencing, NC Start without referencing. 0: No channel-specific referencing, NC Start with referencing. 1-8: Channel-specific referencing. The number entered here corresponds to the referencing sequence. (When all axes with contents 1 have reached the reference point, then the axes with contents 2 start, etc.).
Clear alarm with the RESET key. Restart part program
