FC 300 Design Guide
Function:
A manually entered Rotor resistance, R
apply to a cold motor. Improve shaft performance
by fine-tuning R . Do not attempt to change
r
par. 1-31 while the motor is running.
R2' can be set as follows:
AMA: The adjustable frequency drive measures
1.
the value on the motor. All compensations
are reset to 100%.
The motor supplier states the value.
2.
The default settings of R2' are used. The
3.
adjustable frequency drive selects the setting
on the basis of the motor nameplate data.
1-33 Stator Leakage Reactance (X1)
Option:
Ohm
Function:
Sets the stator leakage reactance of the
motor. Do not attempt to change par. 1-33
while the motor is running.
X1 can be set as follows:
AMA: The adjustable frequency drive measures
1.
the value on the motor.
The motor supplier states the value.
2.
The default setting of X1 is used. The adjustable
3.
frequency drive selects the setting on the
basis of the motor nameplate data.
1-34 Rotor Leakage Reactance (X2)
Option:
Ohm
Function:
Sets the rotor leakage reactance of the
motor. Do not attempt to change par. 1-34
while the motor is running.
X2 can be set as follows:
AMA: The adjustable frequency drive determines
1.
the value on the motor to determine.
2. The motor supplier states the value.

The default setting of X2 is used. The adjustable
3.
frequency drive selects the setting on the
basis of the motor nameplate data.
1-35 Main Reactance (Xh)
Option:
Ohm
Function:
Sets the main reactance of the motor. Do not attempt
to change par. 1-34 while the motor is running.
Xh can be set as follows:
AMA: The adjustable frequency drive measures
1.
the value on the motor.
The motor supplier states the value.
2.
The default setting of Xh is used. The adjustable
3.
frequency drive selects the setting on the
basis of the motor nameplate data.
1-36 Iron Loss Resistance (Rfe)
Range:
1 - 10.000 Ω
Function:
Sets the equivalent of the R
iron losses in the motor. Do not attempt to change
par. 1-35 while the motor is running. The function
is switched off if 10.000 Ω is chosen.
The iron loss parameter is especially important
in torque control applications. If R
leave par. 1-36 on default setting.
1-37 d-axis Inductance (Ld)
Range:
0.0 - 1000.0 mH
Function:
Set the value of the d-axis inductance. This
parameter is only active when par. 1-10 has the
value [1] PM motor (Permanent Magnet Motor). See
the permanent magnet motor data sheet.
