Remedy: The gradient in the coarse area is calculated as follows:
• Positive quadrant: (MD 5485 - MD 5464) / (MD 5486 -5465)
• Negative quadrant: (MD 5487 - MD 5467) / (MD 5488 - 5468)
Enter a valid combination in the above drive MD.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.

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 maxi-
mum in the saturation area and can therefore not be inverted.
Reactions: - 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 Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:

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.
Reactions: - 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:
