In parameter file transmission, errors are reported in the FPCS or in the package ID of the EFPC,
depending on the type of error.
Error type 1 – The error is displayed in the FPCS (FPCS = xxxx0111)

Error type 2 – Error is displayed in the control bytes (package ID = 011xxxxx)
Byte 3 includes error codes that the motor controller sends to the controller. If the controller sends an
error or the motor controller error results in interruption of parameter file transmission, this is stored as
information in the diagnostic memory of the motor controller. The controller does not send an error
number in the user data. The motor controller answers the controller with the error status without an
error text in the user data.
