IPhaseCurrentUpper
Tip Strip: Upper current dithering setpoint
Units: Amps
Detail: Upper threshold for current dithering set-point in Amps.
IPhaseCurrentLower
Tip Strip: Lower current dithering setpoint
Units: Amps
Detail: Lower threshold for current dithering set-point in Amps.
IPhaseDuration
Tip Strip: Duration of phase. 0 = hold to end of command.
Units: msec
Detail: Duration in milliseconds of each phase. When the duration is reached, operation proceeds to the next
phase. A special duration value of zero means that operation will remain in that phase until the end of the injection
command.
A typical IPhase array configuration for operating piezo direct injectors is shown below.
DIX_Phase1FirstPeakEnable
Tip Strip: Causes phase 2 to begin after current reaches first peak
Detail: Phase1FirstPeakEnable is a software option of the DI Driver module to transfer operation from the first phase
to the second phase upon reaching the first current peak corresponding to the first phase IPhaseCurrentUpper . The
first IPhaseDuration should be set to a minimum value long enough for the first peak to be reached.
