Overview Pulse width modulator



This function block generates a pulse-width-modulated signal at the output (PWM signal). 


Inputs

FG
Enable
Enable. With 1 at the input the PWM signal is 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 on-time as a percentage; this is calculated from the parameter PWM pulse time. A value of 50% and a PWM pulse time of 60 seconds results in an on-time of 30 seconds and an off-time of 30 seconds.
ZE Time on On-pulse time. If the input is not connected, the time from the parameter is used.
ZA Time off Off-pulse time. If the input is not connected, the time from the parameter is used.

Outputs

PI
PWM pulse
PWM signal
PZ
Pulse time
Time until the next pulse change

Parameters

PWM pulse time on
Pulse time in seconds for the on-pulse
PWM pulse time off Pulse time in seconds for the off-pulse
Percent minimum
Limit of the percent input minimum.
Percent maximum Limit of the percent input maximum.
