Inertia Tune
The motor has a large disk attached to the end of its shaft. By default, the Inertia parameter has a value of 2.00. In order to
make sure that the drive’s information is as precise as possible, run an Inertia tune on the drive using CCW to update that value
to match the actual Inertia acting on the motor.
1. In CCW, in the Autotune field, select Inertia Tune.
2. Turn to the drive, and press the green Start button.
Follow the process on the HIM module of the drive.
The drive has now completed its auto tune procedure…. And has updated the remaining parameters determined during the
process.
You can now continue to the next section.
