Operating Instructions, 04/2019, A5E36037884-007
Note
When using the real-time auto tuning function, if the default values are inappropriate, the
host controller cannot run the motor. To run the motor with the host controller, you need to
let the drive tune the parameters automatically through trial run with the real-time auto tuning
function. After the tuning is completed, the host controller can run the motor.
Note
After the real-time auto tuning is activated, do not change other auto tuning related
control/filter parameters since these parameters can be set automatically and your changes
will not be accepted.
Note
The real-time auto tuning may not be performed properly if the following conditions are not
satisfied:
•
Accelerate the motor for 100 ms or more with the acceleration torque.
•
The acceleration/deceleration torque is 15% or more of the rated torque.
Under operating conditions that impose sudden disturbance torque during
acceleration/deceleration or on a machine that its rigidity is poor, auto tuning may not
function properly, either. In such cases, use the one-button auto tuning or manual tuning to
optimize the drive.
