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.
