h
The frequency converter
establishes the setting based
on the motor nameplate
data.
Function:
[0 - Enter the equivalent iron loss
resistance (R ) value to compensate
Fe
for iron loss in the motor.
The R value cannot be found by
Fe
performing an Auto Tune.
The R value is especially important
Fe
in torque control applications. If R
is unknown, leave
parameter P-36 Iron Loss Resistance
(Rfe) on default setting.
Function:
Enter the value of the d-axis
inductance. Obtain the value from the
permanent magnet motor datasheet.
The d-axis inductance cannot be found
by performing an Auto Tune.
Function:
Set the value of the q-axis
inductance. See the motor
datasheet.
Function:
This parameter corresponds to the
inductance saturation of Ld. If the motor
supplier provides an induction curve,
enter the induction value at 200% of the
nominal value.
Function:
This parameter corresponds to the
inductance saturation of Lq. Ideally, this
parameter has the same value as
parameter P-38 q-axis Inductance (Lq). If the

Function:

enter the induction value at 200% of the
nominal value.
Function:
[20 - Adjusts the amplitude of the test pulse
200 %] during position detection at start. Adjust
this parameter to improve the position
measurement.
Function:
Use this parameter to optimize the torque estimate
in the full speed range. The estimated torque is
based on the shaft power, P
sure that the R value is correct. The R
s
formula is equal to the power loss in the motor, the
cable, and the frequency converter. When this
parameter is active, the frequency converter
calculates the R value during power-up, ensuring
s
the optimal torque estimate and optimal
performance. Use this feature in cases when it is
not possible to adjust parameter P-30 Stator
Resistance (Rs) on each frequency converter to
compensate for the cable length, frequency
converter losses, and the temperature deviation on
the motor.
Calibrates at the first start-up after power-up and
keeps this value until reset by a power cycle.
Calibrates at every start-up, compensating for a
possible change in motor temperature since last
start-up. The value is reset after a power cycle.
The frequency converter calibrates the torque at the
first start-up after power-up. This option is used to
update motor parameters:
•
Parameter P-30 Stator Resistance (Rs).
•
Parameter P-33 Stator Leakage Reactance
(X1).
•
Parameter P-34 Rotor Leakage Reactance
(X2).
The frequency converter calibrates the torque at
every start-up, compensating for a possible change
in motor temperature since last start-up. This option
is used to update motor parameters:
