1-36 Iron Loss Resistance (Rfe)
Range: Function:
unknown, leave parameter 1-36 Iron
Loss Resistance (Rfe) on default setting.
1-37 d-axis Inductance (Ld)
Range: Function:
Size [0.0 - Enter line to common direct axis
related 1000.0 inductance of the PM motor. Obtain the
*
mH] value from the permanent magnet motor
data sheet.
If only line-line data are available, divide
the line-line value by 2 to achieve the
line-common (starpoint) value. Alterna-
tively measure the value with an
inductancemeter, this also takes the
inductance of the cable into account.
Divide the measured value by 2 and enter
the result.
This parameter is only active when
parameter 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 parameter 30-80 d-axis
