Autotuning
12.2.1 Off-line
autotuning
(1) This is a function for measuring and automatically setting the motor circuit constant necessary
for the sensorless vector control and sensored vector control.
(2) When the sensorless vector control and the sensored vector control is performed by using the
motor whose circuit constant is unknown, please measure the motor circuit constant by the
offline autotuning function.
(3) When 0(MOTOR DATA) in motor constant selection (H002) is set, a 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)
