 Settings for the Control Methods
Autotuning methods depend on the control method set for the Inverter. Make the settings required by the con-
trol method.
Overview of Settings
Make the required settings in quick programming mode and autotuning mode according to the following flow-
chart.
Note 1. Autotuning is not necessary if the motor constants are already known from a motor test report. Set the E2 motor constants to the test report values
(refer to page 6-119). However, if the length of the motor cable exceeds 50 m, perform autotuning.
2. 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 2 control.
* 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 Inverter is for open-loop vector 1 control (A1-02 = 2).
* 4. If the maximum output frequency is different from the base frequency, set the maximum output frequency (E1-04) after autotuning.
