AC asynchronous motor tuning
If the motor can be disconnected from the load, then please set d0-30/d2-30 to 2(asynchronous motor
complete auto-tuning), then press the RUN key on the keypad. The frequency inverter will automatically
calculate the following parameters of motor:

If the motor cannot be fully disconnected with the load, then please select d0-30/d2-30 as 1 (asynchronous
static auto-tuning), and press the RUN key in the keypad panel.
And the frequency inverter will automatically calculate the following parameters of motor:

Description of synchronous motor identification:
As the EM11 driven synchronous machine system needs the feedback signal from encoder, so uses need to
correctly set the parameter of encoder before identification.
During the identification process of synchronous system, rotation movement is needed. The best
identification method is no-load dynamic running identification, if the condition is not allowed; with-load
dynamic identification is workable.

0: Sensor less vector control (SVC)
It indicates open-loop vector control, and is applicable to high-performance control applications such as
machine tool, centrifuge, wire drawing machine and injection molding machine. One frequency inverter can
operate only one motor.
1: Closed-loop vector control (VC)
It is applicable to high-accuracy speed control or torque control applications such as high-speed paper
making machine, crane and elevator. One Frequency inverter can operate only one motor. An encoder must
be installed at the motor side, and a PG card matching the encoder must be installed at the frequency
inverter side.
2: Voltage/Frequency (V/F) control
It is applicable to applications with low requirements or applications where one frequency inverter operates
multiple motors, such as fan and pump.
Note:
If vector control is used, motor auto-tuning must be performed because the advantages of vector
control can only be utilized after correct motor parameters are obtained. Better performance can be achieved
by adjusting speed regulator parameters in group “d”.
For the permanent magnetic synchronous motor (PMSM), the EM11 does not support SVC. VC is used
generally. In some low requirements applications, you can also use V/F.
