Auto-Tuning Input Data in EZ Open Loop Vector Control Method
To do Auto-Tuning, input data for the items in
that have an "x". 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
H1-xx = 16 [Motor 2 Selection]
. Do not do Control Tuning for applications that switch between
motor 1 and motor 2.
