‹ Settings for the Control Methods
Auto-Tuning methods depend on the control method set for the MxC. Make the settings required by the con-
trol method.
„ Overview of Settings
Make the required settings in the Quick Programming Mode and Auto-Tuning Mode according to the follow-
ing flowchart.
Note: If the motor cable is 50 m or longer, perform Stationary Auto-Tuning onsite for the line-to-line resistance only.
* 1. The default setting of the MxC is for Open Loop Vector Control (A1-02 = 2).
* 2. If the maximum output frequency is different from the base frequency, set the Maximum Output Frequency (E1-04) to the value of the base frequency
after Auto-Tuning the MxC.
