HPV_PID
Tip Strip: HPV PID controller output added to HPVPIDFF. Result is directed to selected PFI LS channel duty
cycle parameter.
Units: %
Detail: Output value from the PID controller. This value is limited by the values in
HPV_ManualOverride
Tip Strip: Causes ManualDC to override HPV PID final output
Detail: When
ON
, causes the PID controller to be bypassed and sets PWM parameters for the HPV with a
constant duty cycle defined by
HPV_ManualDC
Tip Strip: Value to override HPV PID final output when ManualOverride=TRUE
Units: %
Detail: Manual duty cycle applied to HPV when
is enabled.
HPV_MaxDCCalc
Tip Strip: Maximum allowed duty cycle for HPV based on battery voltage and nominal solenoid resistance to
limit current to 3A for channel pair
Units: %
Detail: Maximum duty cycle limit based on the battery voltage and the nominal resistance of the valve. This
value prevents the current from exceeding the limitations of the LS channels driving the HPV solenoid.
HPV_MaxDC
Tip Strip: Maximum allowed duty cycle for HPV. This value is effective if lower than
Units: %
Detail: Maximum allowed duty cycle for HPV. This value is effective if lower than
