Axis %1 drive %2 gain at end of saturation area of valve characteristic is less than
or equal to zero
%1 = NC axis number
%2 = Drive number
The gradient at the end of the saturation area of the valve characteristic is less than or
equal to zero. The saturation area is rounded by a parabola. The parabola has a maxi-
mum in the saturation area and can therefore not be inverted.
- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
The gradient at the end of the saturation area is calculated as follows:
• Positive quadrant: 2 * (1.0 - MD 5485) / (1.0 - MD 5486) - (MD 5485 - MD 5464) / (MD
5486 -5465)
• Negative quadrant: 2 * (1.0 - MD 5487) / (1.0 - MD 5488) - (MD 5487 - MD 5467) / (MD
5488 - 5468)
Enter a valid combination in the above drive MD.
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 zero area and knee area of valve characteristic overlap
%1 = NC axis number
%2 = Drive number
The zero area and the knee area of the valve characteristic overlap.
- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
The zero area and the knee area overlap if:
• Positive quadrant: (MD 5481 + MD 5482) > (MD 5465 - 5466)
• Negative quadrant: (MD 5484 + MD 5482) > (MD 5468 - 5466)
Enter a valid combination in the above drive MD.
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 knee area and saturation area of valve characteristic
overlap
%1 = NC axis number
%2 = Drive number
The knee area and the saturation area of the valve characteristic overlap.
