53-KIXR Correction factor, I * R compensation
The correction factor KIXR corresponds to the resistance measured
between two cables. The correction factor can either be entered or
measured by the inverter.
→
The measurement is started, if 48-IXR = 1 and 53-KIXR = 0.
The inverter then issues a max. of 1/16 of the device voltage for approx.
2 s or permits the flow of a max. current of 50-IN (entered motor rated
current ). The measured value is automatically stored under 53-KIXR .
Caution:
The motor may turn slowly during the measurement.
54-KSC Slip compensation, correction factor [%]
The correction factor 54-KSC is just like the motor rated slip scaled to
the device rated current.

SYN
= Synchron. speed
NN = 52-NN (Motor rated speed)
I
NU
= Inverter rated current
IN = 50-IN (Motor rated current)
COS = 51-COS (cos
ϕ
)
The correction factor can be either entered or calculated by the inverter.
The calculation is started, when 49-SC = 1 and 54-KSC = 0. The
synchronous speed for the calculation is determined from the rated
frequency 43-FN1. The calculated value is automatically stored under
54-KSC.
55-ISEL Actual control selector [Decimal]
The actual control selector determines the type of current limit regulation.
The controlled dimension is the apparent phase current 14-IS.
