OFFLINE AUTOTUNING FUNCTION
This is a function for measuring and automatically setting the motor
circuit constant necessary for the sensorless vector control and 0Hz
domain sensorless vector control.
When the sensorless vector control and the 0Hz domain sensorless vector
control is performed by using the motor whose circuit constant is unknown,
please measure the motor circuit constant by the offline autotuning function.
When 00(WATT general purpose motor) in motor constant selection
(H002/H202) is set, WATT general purpose motor is given a constant which
is initial value.
In most case, the characteristics will be obtained without trouble, even if offline
autotuning is not executed.
(When online autotuning function mentioned later is performed, please be sure
to operate offline autotuning )
