Process Setup
Selection from Menu-> Process Setup
Ramp Up and Ramp Down
The units ( seconds ) are the time taken to
change from minimum output current to
maximum output current, i.e. 0 – 100%.
Smaller changes within this window, will be a
ratio of this value. Commands to change coils
will be delayed by the ramping process.
In RPM regulation mode, the user can adjust
the speed of the change in the set point due to
changing command input. This does not affect
the speed of process regulation at a given set
point.
In load limiting and horsepower limiting mode
the user can adjust the speed of the change in
current due to changing command input.
Process P, I and I Time
These settings are used to tune the units response to input and output changes.
The P and I values have a range of 0 to 255 with default values of P = 10 and I = 2. The Process I time range is
4 to 512ms, default value 50ms. The default values typically produce a slow response time in the system. A
detailed explanation of these settings can be found in this user guide under the heading “PID -- The Basic
Technique for Feedback Control”.
The user can adjust the process control parameters here to tune the rate and aggressiveness of the speed
change relative to feedback as well as system under /overshoot for the speed regulation mode. Note that the
process setup settings, directly affect the output current value to the coil.
Minimum / Maximum RPM or Stop / Slow
The user can adjust the minimum and maximum RPM that is selected by the command input as it goes from its
minimum to maximum value in RPM Regulation mode. In Anti Stall mode, this is the Stop RPM and Slow RPM
set point.
