Sinumerik Alarm 310773 Axis %1 drive %2 gain at end of saturation area of valve characteristic is less than or equal to zero

Sinumerik Alarm 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.

Reactions:
– 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.

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.
