Range: Function:
Size [ 0.0140 - Set the line-to-common stator
related 140.0000 resistance value. Enter the value
*
Ohm] from a motor datasheet or perform
an AMA on a cold motor.
NOTICE
For salient PM motors:
AMA is not available.
If only line-line data is
available, divide the line-line
value by 2 to achieve the line-
to-common (star point) value.
Alternatively, measure the
value with an ohmmeter. This
also takes the resistance of the
cable into account. Divide the
measured value by 2 and enter
the result.
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.
