CamExtEnable
Tip Strip: Enables the cam signal to be extended by a specified number of crank pulses
Detail: The DI Driver System provides an optional extension function applied to the cam signal selected
. The extension function extends the cam signal by the number of crank teeth specified
. The starting reference for the extension is the rising edge of the cam signal input to
the function. Therefore, the resulting extended cam signal will be shorter than the input cam signal if the
value is shorter than the cam input signal. The input to the
function is from
function. The output of the cam extension function is delivered to the
function for encoder patterns, and delivered directly to the EPT function for
. When
Enabled
, the cam signal is extended. When
Disabled
, the cam signal is unaltered. The offset and the
extended cam signals may be monitored in the

CamHistory
Tip Strip: Cam Signal Status
Detail: This parameter is only applicable to EPT types of
. When the EPT is in sync, reports the
state of the cam:
Normal
,
Error
,
Always High
or
Always Low
.
Normal:
Indicated when the cam signal is alternating consistently between high and low upon each crank
trigger wheel feature (M tooth gap or Plus1 tooth).
Error:
Indicated when the cam signal is alternating between high and low, but not consistently upon each
crank trigger wheel feature (M tooth gap or Plus1 tooth).
Always High:
Indicated when the cam signal is constantly high upon each crank trigger wheel feature (M
tooth gap or Plus1 tooth).
