8.5 Estimating the Moment of Inertia
8.5.4 Operating Procedure
8-17
8.5.4
Operating Procedure
Use the following procedure to estimate the moment of inertia ratio.
1.
Click the Servo Drive Button in the workspace of the Main Window of the Sig-
maWin+.
2.
Select Tuning in the Menu Dialog Box.
The Tuning Dialog Box will be displayed.
Click the Cancel Button to cancel tuning.
3.
Click the Execute Button.
Estimating the moment of inertia requires operating the Servomotor and therefore presents
hazards. Observe the following precautions.
• Confirm safety around moving parts.
This function involves automatic operation with vibration. Make sure that you can perform an
emergency stop (to turn OFF the power supply) at any time. There will be movement in both
directions within the set range of movement. Check the range of movement and the directions
and implement protective controls for safety, such as the overtravel functions.
Be aware of the following points if you cancel the moment of inertia estimation while the
Servomotor is operating.
• If you cancel operation with the Servo OFF Button, the Servomotor will stop according to setting
of the Servo OFF stopping method (Pn001 = n.X).
• If you cancel operation with the Cancel Button, the Servomotor will decelerate to a stop and
then enter a zero-clamped state.
