Axis %1, drive %2 gradient in fine range of valve characteristic is less
than/equal to zero
%1 = NC axis number
%2 = drive number
The gradient in the fine area of the valve characteristic is less than or equal to
zero.
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 in the fine area is calculated as follows:
S
positive quadrant: (MD 5464-MD 5480)/(MD 5465-MD 5481)
S
negative quadrant: (MD 5467-MD 5483)/(MD 5468-MD 5484)
Enter a valid combination in the above drive MD.
Cancel alarm on all channels by pressing RESET. Restart part program.
Axis %1, drive %2 gradient in coarse range of valve characteristic is less
than/equal to zero
%1 = NC axis number
%2 = drive number
The gradient in the coarse area of the valve characteristic is less than or equal
to zero.
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 in the coarse range is calculated according to the:
S
positive quadrant: (MD 5485-MD 5464)/(MD 5486-MD 5465)
S
negative quadrant: (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.
