SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Axis %1, drive %2 gradient at end of saturaton range of valve characteris-
tic is less than/equal to zero
%1 = NC axis number
%2 = drive number
The gradient at the end of the saturation range of the valve characteristic is less
than/equal to zero. The saturation range is rounded by a parabola function. The
parabola has a maximum in the saturation region and cannot therefore be
inverted.
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 gradient at the end of the saturation region is calculated according to the:
S
positive quadrant: 2@(1.0–MD 5485)/(1.0–MD 5486)
–(MD 5485–MD 5464)/(MD 5486–MD 5465)
S
negative quadrant: 2@(1.0–MD 5487)/(1.0–MD 5488)
–(MD 5487–MD 5467)/(MD 5488–MD 5468)
Enter a valid combination in the above drive MD.
Cancel alarm in all channels by pressing RESET key. Restart the part program.
Axis %1, drive %2 overlap between zero and breakpoint ranges of valve
characteristic
%1 = NC axis number
%2 = drive number
The zero range and breakpoint range of the valve characteristic are overlap-
ping.
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 zero and breakpoint ranges overlap if:
S
positive quadrant: (MD 5481+MD 5482)>(MD 5465–MD 5466)
S
negative quadrant: (MD 5484+MD 5482)>(MD 5468–MD 5466)
Enter a valid combination in the above drive MD.
Cancel alarm in all channels by pressing RESET key. Restart the part program.
