■ Input Data for EZ Tuning
To do Auto-Tuning, input data for the items in the following table that have an "×". Before starting Auto-Tuning,
prepare the motor test report or record the information on the motor nameplate as a reference.

◆ Control Tuning
To increase drive responsiveness and prevent hunting, use Auto-Tuning to automatically adjust the control-related
parameters.
These types of Auto-Tuning are available for the control system:
• Inertia Tuning
• ASR Tuning
• Deceleration Rate Tuning
• KEB Tuning
Note:
If you do Control Tuning, you cannot set any parameter of H1-xx = 61 [H1-xx: MFDI Function Select = Motor 2 Select]. Do not do
Control Tuning for applications that switch between motor 1 and motor 2.
