<Setting>
• 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
η
.

Note: 1. When the inverter is used with a motor of a different level, verify the input motor’s nameplate parameter
P.302~P.307. The vector control method is heavily dependent upon motor parameters. To achieve a good
control performance, the controlled motor’s correct parameters have to be acquired.
2. When any or many values of P.302~P.309 are manually revised, perform the function of P.997 to reload the
new values of the parameters.
