IMV_Enable
Tip Strip: Enables PWM control of IMV
Detail: Enables the final PWM parameters to the lowside channels configured for IMV via the PFI and LS
Driver Setup window.
IMV_LSChanAsn
Tip Strip: Indicates the PFI Driver lowside channels assigned to drive the IMV. The channel assignment is
configured via the PFI and LS Driver Setup window.
IMV_Freq
Tip Strip: Operating Frequency of IMV PWM command
Units: Hz
Detail: Frequency of the PWM signal to the IMV solenoid.
IMV_Kc
Tip Strip: IMV PID proportional gain
Units: %/bar
Detail: Proportional gain. A value of zero disables proportional, integral, and derivative contributions to the
PID output. (See the equation in Auxiliary PID Controller Setup for reference.) Smaller values cause less
proportional contribution to the PID output. Larger values cause more proportional contribution to the PID
output. Negative values will generate PID outputs that are inversely proportional to the error ( Setpoint –
Process Variable ).
IMV_Kp_Action
Tip Strip: Proportional contribution of IMV PID controller
Detail: Indicates the contribution of the proportional term to the total PID output.
