Parameter Description
Parameter Description
•
If you need real sensorless vector control, you should set P.300 to 3.
Note: 1.The motor capacity has to be at the same level or one level below of the level of the capacity of the inverter.
2. For the auto-tuning function, if motor operation is permitted, set P.301 to 1 (dynamic measurement). At this
point, the load has to be separated from the motor. If the load environment does not permit auto-tuning, set
P.301 to 2 (static measurement) if motoring is running.
3. Real sensorless vector control: measurement by automatic (Auto-tuning) function to enhance the control
performance. Set the motor parameters or do auto measurement function before set P.300 to 3, in ordor to
increase the control accuracy.

•
When the motor can be fully separated from the load, select P.301=1. When the motor is running,
the motor parameter will carry out auto-tuning. Then press
FWD
or
REV
on the keyboard panel for the
inverter to automatically calculate the following parameter: P.308~P.309.
•
When the motor cannot be fully separated from the load, select P.301=2. When the motor is stopped,
the motor parameter will carry out auto-tuning. Then press
FWD
or
REV
on the keyboard panel for the
inverter to automatically calculate the following parameter P.308~P.309.
•
The users can use the motor's nameplate to calculate the idling current. The motor nameplate
parameters used in the calculation are: rated voltage U, rated current I, rated frequency
f
and power
factor .
