Speed controller
Preamble
WRsimulator can be used to insert variable speed drives into folios. The library currently includes SchneiderElectric ATV31 single-phase and three-phase drive objects.
Example us18 - demo_Speed_Drive_ATV31_1ph_2C.xrs illustrates the use of an ATV31 drive to control the speed of a moving table.
- the drive is attached to a text zone edited in WinRelais, which specifies its parameters,
- The first line of the text zone must begin with the command :
- parent = drive name,
- This text zone can be placed anywhere in the diagram,
- If the text field does not exist, the drive is set to default parameters.
