12.14 LS_Convert_2
This function extension is available from version 05.00.00!
This FB serves to execute various conversions/scalings.
• The SB is used in the "AC Drive Profile" application for converting the torque values received and
to be sent via bus (see AC Drive Profile  Internal signal flow ).
• The first path (In1  Out1) is used to convert the torque setpoint for the application.
• The second path (In2  Out2) is used to convert the actual torque value from the application
for the output on the bus.
• The SB can also be used for migrating an 8200 motec project into other applications.
