1652 PWMOut2_Frequency output frequency for PWM output 2
10.4.2 Assignment of output parameters to PWM outputs
Every parameter of the control unit can be read out via PWM outputs. To this end, all
that is necessary is to assign its parameter number to the desired output in 1600 / 1605
PWMOutx_Assign. This makes sense only for measurement or indication values with a
value range greater than [0,1], but in the control itself no limitations are implemented.
Signal output can be inverted (e.g., small PWM ratio for high output values) by entering
the parameter numbers negative in sign. The effect of the parameter number being en-
tered with a negative sign will be that there is a long high-phase for small output values
and a short high-phase for large ones.
Parameterising Example:
PWM output 1 is to be used to read out speed (indication parameter 2000 Speed), and
output 2 to read out the active ignition timing (indication parameter 3910 ActiveIgni-
tionTiming).
