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 FuelSetP
WMIn3RefLow and the upper reference values in
parameters 1501 FuelSetPWMIn1R
efHigh or 1505 FuelSetPWMIn3RefHigh.
The measured value parameters 3500 FuelSetpPWMIn1 or 3504 FuelSetpPWMIn3 show
the PW
M ratio as a percentage, and the measured value parameters 3501
FuelSetpFrequencyIn1 or
3505 FuelSetpFrequencyIn3 show the PW
M frequency.
The selection as a PWM setpoint is made according to
 4.1 Design of the setpoint
generator.
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 FuelS
etPWMIn1_Filter or 1508
FuelSetPWMIn3_Filter. The inputs are filtered exactly as described in
 6.2.2 Filtering
the analogue inputs.
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.
Number Parameter Value Unit
