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.
