Note
Stator Resistance parameter can be used to improve starting torque
Example:
Using an example of estimated value for stator resistance, 0.42% is used. If instead, using 3300V
and 156A as base values, 0.63% is used (instead of the 0.42% originally used.).
Increasing the setting to 0.63% (parameter ID 1080) will result in higher IR compensation, and
would also help in torque production.

Max Description
25.00 Enter the stator resistance of the motor, if
provided.
Use the following formula to convert from
ohms to percent:
[%Rs = 100 * √3 * Rs (in ohms) * (Motor
Current / Motor Voltage)] or use the auto-
tune stage 1 function.
200.00 PMM stator inductance as the sum of leak‐
age inductance plus magnetizing stator in‐
ductance. This is for PMM motors only.
100000.0 Enter the rotor inertia of the motor if known
(1 Kgm 2 = 23.73 lbft
stage 2. See note in auto-tune description
before use.
2.5 Ratio of total q-axis inductance 'L' to d-axis
mutual inductance 'L'. Enter as percent of
base drive impedance. This is used to com‐
pensate for current ripple as the rotor poles
interact with stator magnetic fields.
1.00 Set the maximum exciter current when start‐
ing a SM with a DC exciter (SMDC mode).
1.00 Initial magnetizing current for starting SM
with DC exciter.
