Properties and actions
To control the behavior of the Pulse decoder I/O, several properties are available. These can be accessed through a popup menu which is shown when the I/O is right clicked.
The Voltage property sets the high and low level for signal edge detection. Several standard values are available that set both levels at once. A user defined setting is available to set both levels individually.
The Step size property indicates the physical size of one encoder step, in relation to the selected Unit. When the unit is set to e.g. meter, and there are 1000 encoder pulses per meter, Step size needs to be set to 0.001, which can also be entered as 1/1000 or as 1m (where m stands for milli).
The property Offset adds an starting offset in Unit to the determined encoder position.
Pulses per revolution
The property Pulses per revolution allows to set a number of pulses per revolution for the decoder. This setting limits the output of the encoder between zero and the selected number of pulses. When the encoder reaches a limit and then continues moving in the same direction, the output is reset to the other limit and starts counting again. This can be useful for applications where an encoder is connected to a rotating object.
The Swap inputs action can be used to change the direction of movement.
