When F107=1 with valid password, the user must enter correct user’s password after power on
or fault reset if you intend to change parameters. Otherwise, parameter setting will not be
possible, and a prompt “Err1” will be displayed.

Rated current and rated power can only be checked but cannot be modified.
Software Edition No. can only be checked but cannot be modified.
·0: 0: Sensorless vector control is suitable for the application of high-performance requirement.
One inverter can only drive one motor.
2: V/F control is suitable for common requirement of control precision or one inverter drives
several motors.
3: Vector control 1 is auto torque promotion, which has the same function of F137=3. While
studying motor parameters, motor does not need to be disconnected with load. One inverter
can only drive one motor.
Note:

It is necessary to study the parameters of motor before inverter runs in the sensorless
vector control.

Under sensorless vector control, one inverter can only drive one motor and the power of
motor should be similar to the power of inverter. Otherwise, control performance will be
decreased or the system cannot work properly.

The operator may input motor parameters manually according to the motor parameters
given by motor manufactures.

Usually, the motor will work normally by inverter’s default parameters, but the inverter’s
best control performance will not be acquired. Therefore, in order to get the best control
performance, please study the parameters of motor before inverter runs in the sensorless
vector control.
