Manual Entry w/ Motor
Data Sheet
T2-01 = 0
•
When the information from the motor
test report or motor nameplate is
available.
•
Rotational/Stationary Auto-Tuning that
energizes the motor is not done.
Manually input the necessary motor
parameters.

PM Stationary Auto-
Tuning
T2-01 = 1
•
When the information from the motor
test report or motor nameplate is not
available.
Note:
With Stationary Auto-Tuning, the
energized drive stays stopped for
approximately 1 minute. During this
time, the drive automatically measures
the necessary motor parameters.

PM Stationary Auto-
Tuning for Stator
Resistance
T2-01 = 2
•
After Auto-Tuning, the wiring distance
between the drive and motor changed
by 50 m (164 ft) or more.
•
When the motor output and drive
capacity are different.

PM Motor Code Selection
T2-01 = 4
•
When the information from the motor
test report or motor nameplate is not
available.
•
When you can decouple the motor and
load and the motor can rotate freely
while Auto-Tuning.
•
The drive will automatically set the
values measured during Auto-Tuning
to the motor parameters.

High Frequency Injection
T2-01 = 5
•
Automatically sets the control
parameters that are necessary to set
n8-
35 = 1 [Initial Pole Detection Method
= High Frequency Injection]
or
n8-57
= 1 [HFI Overlap Selection =
Enabled]
.
•
Applicable to IPM motors only.
•
Do Auto-Tuning with the motor
connected to the drive.
Note:
When you set
n8-35 = 1
or
n8-57 = 1
,
do High Frequency Injection Auto-
Tuning. Set the data on the motor
nameplate to the drive before you do
High Frequency Injection Auto-
Tuning. In High Frequency Injection
Auto-Tuning, the drive energizes the
stopped motor and automatically
adjusts the parameters.
