MOTER CONSTANT SELECTION
Motor constant used in sensorless vector control and 0Hz domain sensorless vector control can be selected from the following the three.
(1) WATT general purpose motor constant
(2) Motor constant measured in offline autotuning
(3) Optional setting motor constant

Note) In first control method, it is possible to select setting range 00 - 05.
In second control method, it is possible to select setting range 00 - 04.
In third control method, it is possible to select setting range 00 - 01.
Optional setting of motor constant
When motor constant is set optionally, function code is as the following below.
First control is valid and motor constant is 00 Input H020 - H024 directly.
First control is valid and motor constant is 01/02 Input H030 - H034 directly.
Second control is valid and motor constant is 00 Input H220 - H224 directly.
Second control is valid and motor constant is 01/02 Input H230 - H234 directly.
When offline autotuning is not executed, in H030/H230 - H034/H234, the same frame constant as the constant
(WATT general purpose motor constant) is set
.
