5.2.5 1-3* Adv. Motor Data

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.

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.
