Sinumerik Alarm 300769 Axis %1 drive %2 denominator bandwidth > double natural frequency
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
The bandwidth denominator of a current or speed setpoint filter is greater than twice the natural frequency. This error message is only issued for the general bandstop filter if:
• Speed setpoint filter 1:
• MD 1516 > 0.0 or
• MD 1520 <> 100.0
• Speed setpoint filter 2:
• MD 1519 > 0.0 or
• MD 1521 <> 100.0
• Current setpoint filter 1:
• MD 1212 > 0.0
• Current setpoint filter 2:
• MD 1215 > 0.0
• Current setpoint filter 3:
• MD 1218 > 0.0
• Current setpoint filter 4:
• MD 1221 > 0.0
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– NC not ready.
– Channel not ready.
– Channel not ready.
– NC Stop on alarm.
– NC Start disable in this channel.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.
Remedy:
Please inform the authorized personnel/service department. The bandwidth denominator of a current or speed setpoint filter must be less than twice the natural frequency.
