Description
type)
stopped position. Measures stator resistance (Rs),
leakage inductance (Lsigma), stator inductance
(Ls), no-load current (Noload Curr), and rotor time
constant (Tr).
As the motor is not rotating while the parameters
are measured, the measurements are not affected
when the load is connected to the motor spindle.
However, when measuring parameters, do not
rotate the motor spindle on the load side.
3
Rs+Lsigma
(rotating
type)
Measures parameters while the motor is rotating.
The measured motor parameters are used for
auto torque boost or sensorless vector control.
6
Tr (Static
type)
Measures the rotor time constant (Tr) with the
motor in the stopped position and Control Mode
(dr.09) is set to 4 (IM Sensorless).

Displays motor parameters measured by auto tuning.
For parameters that are not included in the auto tuning measurement
list, the default setting will be displayed.
• Perform auto tuning ONLY after the motor has completely stopped running.
• Before you run auto tuning, check the motor pole number, rated slip, rated current,
rated voltage and efficiency on the motor’s rating plate and enter the data. The default
parameter setting is used for values that are not entered.
• When measuring all parameters when motor is static after selecting 2[(All(Static type)]
at bA20 (auto tuning), the accuracy is rather less than the method of selecting 1 (ALL)
and measuring the parameters when the motor is rotating. This means that the
performance sensorless operation may be lowered. Therefore, run static type auto
tuning by selecting 2 (All) only when the motor cannot be rotated (when gearing and
belts cannot be separated easily, or when the motor cannot be separated mechanically
from the load).
