Adv. Motor Data - Danfoss VLT AutomationDrive FC 301 Programming Manual

Programming Guide | VLT® AutomationDrive FC 301/FC 302
If 1 of the settings in parameter group 1-2* Motor Data is changed, parameter 1-30 Stator Resistance (Rs) to parameter 1-39 Motor
Poles return to default setting.
AMA works problem-free on 1 motor size down, it typically works on 2 motor sizes down, it rarely works on 3 motor sizes down,
at it never works on 4 motor sizes down. Remember that the accuracy of the measured motor data is poorer when operating on
motors than the nominal drive size.

1-3* Adv. Motor Data

6.3.5
The following parameters are only available in FC 302:
Parameter 1-37 d-axis Inductance (Ld)
l
Parameter 1-38 q-axis Inductance (Lq)
l
Parameter 1-40 Back EMF at 1000 RPM
l
Parameter 1-44 d-axis Inductance Sat. (LdSat)
l
Parameter 1-45 q-axis Inductance Sat. (LqSat)
l
Parameter 1-45 q-axis Inductance Sat. (LqSat)
l
This parameter group contains parameters related to:
Motor nameplate load compensations.
l
Application load type.
l
Electronic brake function for quick stop/hold of the motor.
l
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.
