Auto-Tuning Interruption And Fault Codes; Auto-Tuning Operation Example - YASKAWA T1000A Technical Manual

4.6 Auto-Tuning
• Check the area around the motor to ensure that nothing will accidentally cause the motor to rotate during the Auto-
Tuning process.
• Use Stationary Auto-Tuning 1 when the motor test report is not available. If the motor test report is available, perform
Stationary Auto-Tuning 2 instead.
Stationary Auto-Tuning for Line-to-Line Resistance and PM Motor Stator Resistance
• Perform when entering motor data manually while using motor cables longer than 50 m.
• If the motor cables have been replaced with line over 50 m long after Auto-Tuning as already been performed, then
execute Stationary Auto-Tuning for line-to-line resistance.

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.
u 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.
