4.7 Auto-Tuning
112 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual
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.
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.
