Change Tuning and Integral Settings
Travel Tuning
D Travel Tuning Set, there are eleven Travel Tuning Sets to choose from. Each tuning set provides a preselected value
for the digital valve controller gain settings.
D Travel Proportional Gain, for travel control tuning only. Changing this parameter will also change the tuning set to
Expert.
D Travel Velocity Gain, for travel control tuning only. Changing this parameter will also change the tuning set to
Expert.
D Travel MLFB Gain is the minor loop feedback gain for travel control only. Changing this parameter will also change
the tuning set to Expert.
D Travel Integral Gain (also called reset), is the ratio of the change in output to the change in input, based on the
control action in which the output is proportional to the time integral of the input.
D Travel Integral Dead Zone is a window around the Primary Setpoint in which the integral action is disabled. The dead
band is configurable from 0 to 2%.
D Travel Integral Limit Hi provides an upper limit to the integrator output. The high limit is configurable from 0 to
100% of the I/P drive signal.
D Travel Integral Limit Lo provides a lower limit to the integrator output. The low limit is configurable from -100 to 0%
of the I/P drive signal.
D Travel Integral Enable is used to enable the integral setting to improve static performance by correcting for error
that exists between the travel target and actual travel.
Pressure Tuning
D Pressure Tuning Set, there are twelve Pressure Tuning Sets to choose from. Each tuning set provides a preselected
value for the digital valve controller gain settings.
D Pressure Proportional Gain, for pressure control tuning only. Changing this parameter will also change the tuning
set to Expert.
D Pressure Integral Gain (also called reset), is the ratio of the change in output to the change in input, based on the
control action in which the output is proportional to the time integral of the input. Changing this parameter will
also change the tuning set to Expert.
D Pressure Integral Dead Zone is a window around the Primary Setpoint in which the integral action is disabled. The
dead band is configurable from 0 to 2%.
D Pressure Integral Limit Hi provides an upper limit to the integrator output. The high limit is configurable from 0 to
100% of the I/P drive signal.
D Pressure Integral Limit Lo provides a lower limit to the integrator output. The low limit is configurable from -100 to
0% of the I/P drive signal.
D Pressure MLFB Gain is the minor loop feedback gain for the pressure control tuning set. Changing this parameter
will also change the tuning set to Expert.
