*3 When L2-29 = 2, 3, or 4 [KEB Method = Single KEB2 Ride-Thru, System KEB1 Ride-Thru, or System KEB2 Ride-Thru], the drive
will automatically adjust L2-06 [KEB Decel Time].
◆ Precautions before Auto-Tuning
Examine the topics in this section before you start Auto-Tuning.
■ Prepare for Basic Auto-Tuning
• You must input data from the motor nameplate or motor test report to do Auto-Tuning. Make sure that this data
is available before you do Auto-Tuning.
• For best performance, make sure that the drive input supply voltage is equal to or more than the motor rated
voltage.
Note:
Better performance is possible when you use a motor with a rated voltage that is less than the input supply voltage (by 20 V for 200 V
class models or by 40 V for 400 V class models). This is very important when you operate the motor at more than 90% of base speed,
where high torque precision is necessary. If the input power supply is equal to the motor rated voltage, the drive output voltage will not
be sufficient and performance will decrease.
• Push on the keypad to cancel Auto-Tuning.
• If a Safe Disable input signal is input to the drive during Auto-Tuning, Auto-Tuning measurements will not
complete successfully. If this occurs, cancel the Auto-Tuning, then do it again.

WARNING! Crush Hazard. Wire a sequence that will not let a multi-function output terminal open the holding brake during
Stationary Auto-Tuning. If the holding brake is open during Stationary Auto-Tuning, it can cause serious injury or death.
WARNING! Sudden Movement Hazard.. Before you do Rotational Auto-Tuning, disconnect the load from the motor. The load
can move suddenly and cause serious injury or death.
WARNING! Crush Hazard. Rotational Auto-Tuning rotates the motor at 50% or more of the motor rated frequency. Make sure
that there are no issues related to safety in the area around the drive and motor. Increased motor frequency can cause serious
injury or death.
WARNING! Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.
■ Precautions before Rotational Auto-Tuning
WARNING! Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.
• Uncouple the drive from the motor before Rotational Auto-Tuning to prevent drive malfunction. If you do
Rotational Auto-Tuning with the motor connected to a load that is more than 30% of the motor duty rating, the
drive will not correctly calculate the motor parameters and the motor can operate incorrectly.
• When the load is 30% or less of the motor duty rating, you can do Auto-Tuning with the motor connected to a
load.
• Make sure that the motor magnetic brake is released.
• Make sure that external force from the machine will not cause the motor to rotate.
