UCC2813-0: SPICE Model - Error message with LTSpice

Part Number: UCC2813-0
Other Parts Discussed in Thread: TINA-TI


I used Spice-Model: UCCx813-0 and UCCx800 (Date: 06/21/10;Model Version: Final 1.10) and I always get an error message:

u1:vr2: Missing value, assumed 0V @ DC

The simulation is wrong and the voltage on pin vcc = 0V (Stimuli: 8V DC-Source). What is wrong, the parameter vr2 is a internal value from Spice-Model?
