3.2 L_8200Initialization − Frequency inverter initialisation

Function block

This FB is used to initialise the frequency inverter with the parameters which were previously defined

by an instance or copy of the FB L_8200Parameter.

Note!

The FB must be called cyclically because the data are internally transmitted to the frequency inverter

via the FBL_ParWrite.

· Depending on the amount of data to be transmitted, the data transfer may take several cycles.

· If the data transfer has been successful, the message outputbParDone will be set to TRUE.

· When the data transfer has been completed ( bParDone = TRUE), the parameterisation is

complete and the FBsL_8200Parameter and L_8200Initialization need not be called again.
