To calculate the inverse characteristic, the knee-point in the positive quad-
rant of the valve characteristic is defined in MD 5464 and MD 5465 and in
the negative quadrant with MD 5467 and MD 5468.
The positive and negative valve flows at the knee-point in relation to the
nominal flow (MD 5107) are entered in 5467 and MD 5464 respectively.
The positive and negative valve voltages at the knee-point in relation to the
nominal valve voltage (MD 5109) are entered in MD 5465 and MD 5468
respectively.
When the same values (defaults) are set in MD 5464 and MD 5465, the
characteristic is linear (without breakpoint in the zero range (default) and
without saturation (default)).
This breakpoint data is preset from the valve data (MD 5110, MD 5111) dur-
ing the "Calculate controller data" operation. The presettings can be altered
later. The rounding range is not a valve data and is therefore only preset to a
default value. It can however be changed later by the user (MD 5466). If
necessary, a measurement can be taken to obtain a precise setting.
Note
A constant machining velocity of the drive directly at the knee-point of the valve
is not recommended.
