1-36 Iron Loss Resistance (Rfe)
Range: Function:
The R
performing an AMA.
The R
in torque control applications. If R
is unknown, leave 1-36 Iron Loss
Resistance (Rfe) on default setting.

This parameter is only active when
1-10 Motor Construction has the value [1]
PM, non-salient SPM (Permanent Magnet
Motor).
For a selection with one decimal, use
this parameter. For a selection with
three decimals, use 30-80 d-axis
Inductance (Ld).

1-39 Motor Poles
Range: Function:
Size related [2 - 100 ] Enter the number of motor poles.

Table 3.4
The table shows the number of poles for normal speed
ranges of various motor types. Define motors designed for
other frequencies separately. The motor pole value is
always an even number, because it refers to the total
number of poles, not pairs of poles. The frequency
converter creates the initial setting of 1-39 Motor Poles
based on 1-23 Motor Frequency and 1-25 Motor Nominal
Speed.
1-40 Back EMF at 1000 RPM
Range: Function:
Size [ 10. - Set the nominal back EMF for the motor
related 9000 V] when running at 1000 RPM. This
