Übersicht Pulse width modulator



Mit diesem Funktionsblock wird am Ausgang ein pulsbreitenmoduliertes Signal (PWM-Signal) erzeugt. 


Inputs

FG
Enable
Enable. With 1 at the input the PWM signal is sent to the output. This input is optional, if this input is not connected, the block is always enabled.
PW
Pulse width [%]
Pulse width in percent. Specifies the switch-on time in percent, this is calculated by the parameter PWM pulse time, a value of 50% and a PWM pulse time of 60 seconds results in a switch-on time of 30 seconds and a switch-off time of 30 seconds.

Outputs

PI
PWM Impuls
PWM Signal
PZ
Pulse time
Time to the next pulse change

Parameter

PWM Pulse time
Pulse time in seconds
Percent Minimum
Limitation percentage input minimum.
Prozent Maximum Limitation percentage input Maximum.
