Sinumerik Alarm 25105 Axis %1 measuring systems differ considerably
Parameters:
%1 = Axis name, spindle number
Definitions:
The two measuring systems differ considerably, i.e. the cyclically monitored actual value difference between the two measuring systems is greater than the associated tolerance value set in the machine data $MA_ENC_DIFF_TOL. This can only occur when both measuring systems are active ($MA_NUM_ENCS = 2) and referenced. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– Mode group not ready.
– Channel not ready.
– 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 machine data for the active, selected encoders. Check the machine data relating to encoder ($MA_ENC_DIFF_TOL) tolerance.
Program Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
