Possible Causes

Solutions

The permissible range of the voltage value for the field weakening operation "U_mains-min and U_mains-max" of the IDN P-0-455 is calculated during initialization and compared with the parametrized value in the IDN P-0-0201.

"U_mains-min" less than (P-0-0201 minus P-0-0203) and "U_mains-max" greater than (P-0-0201 plus P-0-0202). Check the IDNs for plausible values.
