Code Description
(Tr), etc., while the motor is rotating. If the load is
connected to the motor, the parameters may not
be measured accurately. For accurate
measurements, remove the load attached to the
motor. Also, the rotor time constant (Tr) will be
measured in a stopped position.
2 All (static type) Measures all parameters while the motor is in the
stopped position. Measures stator resistance (Rs),
stator inductance (Lsigma), no-load current
(Noload Curr), rotor time constant (Tr), etc. The
measurements are not affected when the load is
connected to the motor spindle. However, when
measuring parameters, do not rotate the motor
from 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 IM Sensorless.
7 All (PM) When dr.09 (Control Mode) is set to 6 (PM
Sensorless), the motor parameters are measured
in the stopped position. Check the motor’s name
plate for motor specifications, such as the base
frequency (dr.18), motor rated voltage (bA.15),
pole number (bA.11). Then, perform auto tuning
by setting bA.20 to 7 [All (PM)]. The auto tuning
operation will configure parameters bA.21 (Rs),
bA.28 [Ld (PM)], bA.29 [Lq (PM)], and bA.30 (PM
Flux Ref).
bA.14 Noload Curr,
bA.21 Rs–bA.24 Tr
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 name plate and enter the data. The default parameter setting is used
for values that are not entered.
•
When measuring all parameters after selecting 2 ( All - static type) at bA20: compared with rotation
type auto tuning where parameters are measured while the motor is rotating, parameter values
measured with static auto tuning may be less accurate. Inaccuracy of the measured parameters
