Error = [°]), by modifying the value of P731.32.
When you are satisfied with the result, restore the system to Normal Operation, as follows:
• Set "Function selection" to "Return": PNU 52=0;
• Set "Access level" to "Normal operation": PNU 51=1;
• Start the inverter, open QS2 again, and check that the SYNC is as shown in the example in "Fig. 18";
• Close QS2 again;
• Procedure complete for UPS1;
NOTE 2:
This offset compensation procedure must be repeated for ALL the 80-eXL/EXL S1//COREs connected to MB-
SM.
