‹ Settings for the Control Methods
Autotuning methods depend on the control method set for the Drive. Make the settings required by the control
method.
„ Overview of Settings
Make the required settings in quick programming mode and autotuning mode according to the following flow-
chart.
Note If the motor cable changes to 50 m or longer for the actual installation, perform stationary autotuning for the line-to-line resistance only on-site.
* 1. Use rotational autotuning to increase autotuning accuracy whenever it is okay for the motor to be operated. Always perform rotational autotuning when
using open-loop vector control 2.
* 2. If there is a reduction gear between the motor and PG, set the reduction ratio in F1-12 and F1-13.
* 3. The default setting of the Drive is for open-loop vector control 1 (A1-02 = 2).
* 4. If the maximum output frequency and base frequency are different, set the maximum output frequency (E1-04) after autotuning.
