Sinumerik Alarm 300506 Axis %1 drive %2 NC sign-of-life failure
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
Upon servo enable, the NC must update the sign-of-life monitoring in each position control cycle. In case of error, sign-of-life monitoring has not been updated. Cause:
• a) NC no longer updates the sign-of-life as a reaction to an alarm (e.g. 611D alarm)
• b) Fault occurred during communication via the drive bus
• c) Hardware error on the drive module
• d) NC fault
• e) For 840D: Value of the machine data MD10082: $MN_CTRLOUT_LEAD_TIME (Off- set of the setpoint acceptance instant) is too great
• f) MD 1003 $MD_STS_CONFIG not set correctly (e.g. zero) 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.
• for a) Determine whether the sign-of-life monitoring failure is a sequential fault. A sequential fault arises, e.g. through: Fault/alarm from axis x with an n-axis configuration. If this fault profile arises, the above-stated error message will be issued for all n- axes, although there is only a fault/alarm at axis x. ==> Remedy the error at axis x ==> sign of life of the other axes is irrelevant. • for b) Check cable connection, perform remedial measures (check shielding or ground connection).
• for c) Change controller module.
• for d) See NC Diagnostics Guide and change NC hardware if necessary.
• for e) Correctly set the machine data 840D MD10082: $MN_CTRLOUT_LEAD_TIME (Offset of the setpoint acceptance instant) with the machine data MD10083: $MN_CTRLOUT_LEAD_TIME_MAX (Maximum settable offset of the setpoint acceptance instant).
• for f) Check MD 1300 $MD_STS_CONFIG.
Program Continuation:
Switch control OFF – ON.
