n Notes on Rotational Auto-Tuning
• Decouple the load from the motor to achieve optimal performance from Rotational Auto-Tuning. Rotational Auto-Tuning
is best suited for applications requiring high performance over a wide speed range.
• If it is not possible to decouple the motor and load, reduce the load so it is less 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.
n Notes on Stationary Auto-Tuning
Stationary Auto-Tuning modes analyze motor characteristics by injecting current into the motor for approximately one minute.
WARNING! Electrical Shock Hazard. When executing stationary Auto-Tuning, voltage is applied to the motor before the motor rotates. Do
not touch the motor until Auto-Tuning is completed. Failure to comply may result in injury or death 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.

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.
