4.5 Test Run
164 YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Rotational Auto-Tuning for V/f Control
• Motor rotates during Auto-Tuning.
• Sets parameters required for torque compensation, slip compensation, energy
savings, and speed search.
• Available only when the drive is set for V/f Control (A1-02 = 0).
• Required to perform Estimation-Type Speed Search when using V/f Control.
Rotational Auto-Tuning for Open Loop Vector Control
• Used only when in Open Loop Vector Control.
• Perform only with the motor uncoupled from the load for applications requiring
high performance over a wide speed range.
• Disconnect the load before Auto-Tuning the drive and motor. Performing
Rotational Auto-Tuning with the load connected will set motor parameters
incorrectly, and also be dangerous because irregular motor rotation will occur.
• It is possible to perform Rotational Auto-Tuning with a connected load if the
load is less than 30% of the rated load.
• Ensure a motor-mounted brake is fully released.
• Connected machinery should not produce enough power to rotate the motor.
Stationary Auto-Tuning for Terminal Resistance Only
• If the motor cable lead length has been significantly modified after Auto-Tuning
has already been performed, perform Stationary Auto-Tuning with the new
cables.
• Perform when using motor cables over 50 meters long with V/f Control.
Note: When auto-tuning a motor that is used on an application in conjunction with a brake,
take special precaution to ensure the brake stays applied.

Auto-Tuning Fault Codes
Auto-Tuning is interrupted when an abnormal measurement is calculated or if
is pressed before Auto-Tuning is complete.
Figure 4.28 displays an example of the LED Operator lights when Auto-Tuning is
interrupted.
