PFI Phase Setpoint & Duration
Tip Strip: Current setpoint for this phase, Duration for this phase
Units: Setpoint: Amps, Duration: msec
Detail: These parameters configure the current and duration of the two phase within each injection
command. 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. Using the values
specified in the above control image, the current profile to the injector would be 4A for 1.5 msec, followed by
1A for the remainder of the injection command.
PFIX_ChanEnable
Tip Strip: Enables PFI channel
Detail: Enables individual PFIX Channel of the PFI Driver module.
PFIX_RecircAlways
Tip Strip: Allows current to recirculate always while command is ON and OFF
Detail: When
ON
, the current to the load is allowed to re-circulate, or “freewheel” at all times. When
OFF
, the
current to the load is allowed to re-circulate only during injection commands, while current is being controled
to the specified level. When
OFF
, the current to the load is cutoff sharply at the end of the injection command
with the use of a zener diode internal to the module.
PFI 2 - 4
