Explanatory notes
• The precondition for IxR load compensation is correct setting of
parameters 159-MOCOS (cosϕ) and 158-MOCNM (motor rated
current INM).
• If the output frequency exceeds the motor rated frequency (parame-
ter FNx), the IxR load compensation is deactivated. IxR load com-
pensation takes effect as from frequency CIFMx and is 100% active
as from frequency CIFMx + CIFRx.
• The stator resistance required for the function is automatically cal-
culated during initial commissioning and stored in parameter KIXRx
(IxR compensation factor).
• Parameter values marked by an asterisk (*) in the “Factory setting”
(FS) column are dependent on the device power output. The values
correspond to an asynchronous IEC standard motor with the rated
device power output.
