SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Axis %1, drive %2 denominator bandwidth exceeds double natural fre-
quency
%1 = NC axis number
%2 = drive number
The denominator bandwidth of a velocity filter is greater than 2x the natural fre-
quency.
The error message is only generated for the general bandstop if the following
applies:
Velocity filter 1:
MD 5516 > 0.0 or
MD 5520 <> 100.0
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 denominator bandwidth of a velocity filter must be smaller than twice the
natural frequency.
Velocity filter 1:
S
BSF bandwidth drive MD 5515: SPEED_FILTER_1_BANDWIDTH
S
BSF blocking frequency drive MD 5514:
SPEED_FILTER_1_SUPPR_FREQ
S
BSF natural frequency drive MD 5520: SPEED_FILTER_1_BS_FREQ
MD 5515 v 2 * MD 5514 * 0.01 * MD 5520
Cancel alarm in all channels by pressing RESET key. Restart the part program.
Axis %1, drive %2 proportional gain of force controller too high
%1 = NC axis number
%2 = drive number
The P gain of the force controller in MD 5242: FORCECTRL_GAIN is too high.
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.
Enter a lower value for the force controller P gain in MD 5242:
FORCECTRL_GAING.
Cancel alarm in all channels by pressing RESET key. Restart the part program.
