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
frequency.
The error message is only generated for the general bandstop if the following
applies:
Speed filter 1:
MD 5516 > 0.0 or
MD 5520 <> 100.0
NC not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
The denominator bandwidth of a velocity filter must be less than twice the natu-
ral frequency.
Speed filter 1:
S
BSP bandwidth drive MD 5515: SPEED_FILTER_1_BANDWIDTH
S
BSP blocking frequency drive MD 5514:
SPEED_FILTER_1_SUPPR_FREQ
S
BSP natural frequency drive MD 5520: SPEED_FILTER_1_BS_FREQ
MD 5515 v 2 * MD 5514 * 0.01 * MD 5520
Cancel alarm on all channels by pressing RESET. Restart 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.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
Enter a lower value for the force controller P gain in MD 5242:
FORCECTRL_GAING.
Cancel alarm on all channels by pressing RESET. Restart part program.
