Pulse width modulator
Description
The pulse width modulator (PWM) (for SIMOCODE pro V PN/pro V EIP basic units only)
modulates the analog input value into a digital output signal "PWM Output" with a variable
duty factor that is proportional to the analog input value.
If you interconnect the input to "Fixed value," the input is assigned the parameterized
constant "Input (const)." In this case, the edit field for the constant is activated. You can
enter a value between 0 and 65535.
The "Pulse Width Modulator" function block consists of:
● one analog plug (input)
● One digital socket (PWM output)
● Logic.
