Valve Gain - The span of error between the onset of valve
operation and the point at which the valve is fully open is deter-
mined by the valve gain setting. In this case, the units dis-
played (percentage) are arbitrary, but higher numbers suggest
more vigorous valve action. With the gain set to 100%, the
slightest error will fully open the appropriate valve. This setting
should be left at 50% until after the minimum pulse width has
been set and the hydraulics tested to see in which direction
you would like to adjust this setting. The higher the number the
more aggressive the hydraulic system. Conversely the lower
the number the less aggressive the hydraulic system will be.
Balancing Danfoss Ratio-Metric Servo - These three
settings are important in balancing the hydraulic servo. The
most important of the three is the valve dead-band, it must
be set to a realistic value that your machine’s geometry can
handle. The next in importance is the Minimum DC, this sets
the hydraulics systems slowest speed, if too fast the servo will
never have the ability to balance and control grade. The last
setting, Valve Gain sets the over all hydraulic aggressiveness.
If set too high the cylinder speed changes will be too large and
the servo will never be able to balance. Conversely set too low
the cylinder speed changes will be too small, a balance servo
will not be achieved. A balance in these three settings while the
machine is working under it’s normal load should give you good
hydraulic control.
