Notes on Inertia Tuning and ASR Gain Auto-Tuning
WARNING! Electrical Shock Hazard. When executing Inertia Tuning or ASR Gain Auto-Tuning, voltage is applied to the motor even before
it rotates. Do not touch the motor until Auto-Tuning is completed. Failure to comply may result in injury or death from electrical shock.
• Perform both tuning methods with the machine connected to the motor, but without the load applied.
• The motor will rotate during the Auto-Tuning process. Make sure the areas around the motor and connected machinery are
clear.
• The drive will let the system rotate at a certain speed while superimposing a sine wave test signal. Make sure this tuning
process does not cause any problem or malfunction in the machine before using it.
• Ensure the motor-mounted brake is fully released if installed.
• Connected machinery should be allowed to rotate the motor.
