SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Axis%1, drive%2 numerator bandwidth exceeds double blocking fre-
quency
%1 = NC axis number
%2 = drive number
The numerator bandwidth of a velocity or control output filter is greater than 2x
the blocking frequency.
The error message is only generated for the general bandstop if the following
applies:
S
Velocity filter 1:
MD 5516 > 0.0 or
MD 5520 <> 100.0
S
Control output filter 1 in velocity controller:
MD 5212 > 0.0
S
Control output filter 2 in velocity controller:
MD 5215 > 0.0
NC not ready
Switchover for entire channel via MD might be possible.
Channel not ready.
NC Stop in response to alarm.
NC Start disable.
The NC switches to follow-up mode.
Alarm is displayed.
Interface signals are set.
The numerator bandwidth must be less than twice the blocking frequency.
S
Velocity filter 1:
– BSF bandwidth numerator drive MD 5516:
