5.2.5 1-3* Adv. Motor Data
N O T I C E
The following parameters are only available in FC 302:
Parameter 1-37 d-axis Inductance (Ld)
Parameter 1-38 q-axis Inductance (Ld)
Parameter 1-40 Back EMF at 1000 RPM
Parameter 1-44 d-axis Inductance Sat. (LdSat)
Parameter 1-45 q-axis Inductance Sat. (LqSat)
Parameter 1-49 q-axis Inductance Sat. Point
This parameter group contains parameters related to:
Motor nameplate load compensations.
Application load type.
Electronic brake function for quick stop/hold of the motor.
Ensure that the motor data in parameter 1-30 Stator Resistance (Rs) to parameter 1-39 Motor Poles matches the motor. The default
settings are based on standard motor values. If the motor parameters are not set correctly, a malfunction of the drive system may
occur. If the motor data is unknown, running an AMA (automatic motor adaptation) is recommended. See parameter 1-29 Automatic
Motor Adaptation (AMA).
Parameter groups 1-3* Adv. Motor Data and 1-4* Adv. Motor Data II cannot be adjusted while the motor is running.

A simple check of the X

h
sum value is to divide the line-to-line motor voltage by the sqrt(3) and divide this value by the
motor no load current. [VL-L/sqrt(3)]/INL = X

+ X
h
. These values are important to magnetize the motor properly. For high-pole
motors, it is highly recommended to perform this check.

This parameter cannot be adjusted while the motor is running.
Set the line-to-common stator resistance value. Enter the value from a motor datasheet or perform an AMA on a cold motor.
