Table 4.16 Auto-Tuning Input Data
◆ Before Auto-Tuning the Drive
Check the items below before Auto-Tuning the drive.
■
Basic Auto-Tuning Preparations
• Auto-Tuning requires the user to input data from the motor nameplate or motor test report. Make sure this data is
available before Auto-Tuning the drive.
• For best performance, the drive input supply voltage must be greater than the motor rated voltage.
Note: Better performance is possible when using a motor with a base voltage that is 20 V (40 V for 400 V class models) lower than the
input supply voltage.
• To cancel Auto-Tuning, press the STOP key on the digital operator.
• When using a motor contactor, make sure it is closed throughout the Auto-Tuning process.
• Table 4.17 describes digital input and output terminal operation while Auto-Tuning is executed.

■ Notes on Rotational Auto-Tuning
• To achieve optimal performance from Rotational Auto-Tuning, the load should be decoupled from the motor.
Rotational Auto-Tuning is best suited for applications requiring high performance over a wide speed range.
• If motor and load can not be decoupled, reduce the load so that it is no greater than 30% of the rated load. Performing
Rotational Auto-Tuning with a higher load will set motor parameters incorrectly, and can cause irregular motor
rotation.
• Ensure the motor-mounted brake is fully released if installed.
• Connected machinery should be allowed to rotate the motor.
■
Notes on Stationary Auto-Tuning
Stationary Auto-Tuning modes analyze motor characteristics by injecting current into the motor for about one minute.
WARNING! Electrical Shock Hazard. When executing stationary Auto-Tuning, the motor does not rotate, however, power is applied.
Do not touch the motor until Auto-Tuning is completed. Failure to comply may result in injury from electrical shock.
WARNING! Sudden Movement Hazard. If installed, do not release the mechanical brake during stationary Auto-Tuning. Inadvertent
brake release may cause damage to equipment or injury to personnel. Ensure that the mechanical brake release circuit is not
controlled by the drive multi-function digital outputs.
