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
should be set to a minimum value long enough for the first
peak to be reached.
