310773 Axis %1 drive %2 gain at end of saturation area of valve characteristic is
less than or equal to zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 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 maximum in the saturation area
and can therefore not be inverted.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: 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.
Program
Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
310774 Axis %1 drive %2 zero area and knee area of valve characteristic overlap
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The zero area and the knee area of the valve characteristic overlap.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: 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.
Program
Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
