■ 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 from electrical shock.
• Both tuning methods must be performed with the machine connected to the motor but without 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.
◆ Auto-Tuning Interruption and Fault Codes
If tuning results are abnormal or the STOP key is pressed before completion, Auto-Tuning will be interrupted and a fault
code will appear on the digital operator.
