VLT AutomationDrive FC 301/302
Function:
Set the stator leakage reactance of the
motor using one of these methods:
•
Run an AMA on a cold motor.
The frequency converter
measures the value from the
motor.
•
Enter the X value manually.
1
Obtain the value from the
motor supplier.
•
Use the X default setting. The
1
frequency converter establishes
the setting based on the motor
nameplate data.
See Illustration 3.6.
NOTICE
The parameter value is updated
after each torque calibration if
option [3] 1st start with store or
option [4] Every start with store is
selected in parameter 1-47 Torque
Calibration.
NOTICE
This parameter is only relevant for
ASM.
