Table 11: PWM Inputs
The PWM signal is usually transmitted with a range of 5 to 95 % PWM. To scale the
measurement ranges, the lower reference values must be entered in parameters 1500
FuelSetPWMIn1RefLow
or 1504
FuelSetPWMIn3RefLow
and the upper reference values in
parameters 1501
FuelSetPWMIn1RefHigh
or 1505
FuelSetPWMIn3RefHigh
.
The measured value parameters 3500
FuelSetpPWMIn1
or 3504
FuelSetpPWMIn3
show
the PWM ratio as a percentage, and the measured value parameters 3501
FuelSetpFrequencyIn1
or 3505
FuelSetpFrequencyIn3
show the PWM frequency.
The selection as a PWM setpoint is made according to
6.3.1
Filtering the PWM inputs
The measured value of the particular PWM input can be filtered with a digital filter. The
associated parameters are on numbers 1506
FuelSetPWMIn1_Filter
or 1508
FuelSetPWMIn3_Filter
. The inputs are filtered exactly as described in
.
Parameterization example 1:
The setpoint generator selects the filling setpoint with a PWM ratio of between
5 % and 95 %. The analogue stop request is not needed, so the PWM setpoint is
automatically present on Pin 2 and 3 at PWM input 1.
