SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
Axis %1, drive %2 gradient at end of saturation 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 therefore cannot be
inverted.
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 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 on all channels by pressing RESET. Restart 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.
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 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 on all channels by pressing RESET. Restart part program.
