Cause : Reference source parametrization comes when a reference source is simultaneously connected to multiple parameters with different units.

• Check the reference source selection parameters.
• Check the auxiliary code (format XXYY 00ZZ). “XX” and “YY” specify the two sets of parameters where the source was connected to (01 = speed reference chain [22.11, 22.12, 22.15, 22.17], 03 = torque reference chain [26.11, 26.12, 26.16], 04 = other torque-related parameters [26.25, 30.21, 30.22, 44.9]. “ZZ” indicates the conflicting reference source (01…0E = index in parameter group 3, 33 = process PID control, 3D = motor potentiometer, 65 = AI1, 66 = AI2, 6F = frequency input).
