PWM

 Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Generate a PWM signal.

Inputs

Input	Data Type	Range	Unit	Default	Description
XIN	REAL				Input analog value.
XinMin	REAL				Minimum input value.
XinMax	REAL				Maximum input value.
MinPulse	TIME				Minimum pulse When the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated. time on output.
Period Motor systems having a reciprocating or oscillating motor that operates synchronously with the periodicity of the source which supplies the electrical energy. The period of execution of a pipe is the time spent between two successive computations of set values for the same pipe. The period of execution of a pipe is specified by the PERIOD parameter of the input pipe block.	TIME				Period of the output signal.

Outputs

Output	Data Type	Range	Unit	Description
Q	BOOL			Blinking PWM signal.

Remarks

• The input value is truncated to [XinMin .. XinMax] interval.
  • XinMax must be greater than XinMin.

• The signal is TRUE during:

(Xin - XinMin) * Period / (XinMax - XinMin)

PWM1 is a declared instance of PWM function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. block.

PWM1 (rIn, rInMin, rInMax, tMinPulse, tPeriod);
Signal := PWM1.Q;
