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! Before you do Rotational Auto-Tuning, disconnect the load from the motor. The load can move suddenly and 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.
■
Precautions before Stationary Auto-Tuning
•
Make sure that the motor magnetic brake is not open.
•
Make sure that external force from the machine will not cause the motor to rotate.
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.
Automatically Set E2-02 [Motor Rated Slip] and E2-03 [Motor No-Load Current]
If T1-12 = 1 [Test Mode Selection = Yes] when selecting Stationary Auto-Tuning, the drive will automatically set
motor parameters E2-02 [Motor Rated Slip] and E2-03 [Motor No-Load Current] after Auto-Tuning is complete
when you use the motor for the first time in Drive Mode.
After Stationary Auto-Tuning is complete, use this procedures to do the operation in test mode:
1. Check the E2-02 and E2-03 values on the “ Modified Parameters/Fault Log ” screen or the “ Parameters ” screen.
2. Operate the motor in Drive Mode with these conditions:
• Make sure that you connect all wiring between the drive and motor
• Make sure that a mechanical brake on the motor shaft is not locked
• The maximum motor load must be 30% of the rated load.
• Keep a constant speed of 30% of E1-06 [Base Frequency] (default value = maximum frequency) or more for 1
second or longer.
3. After the motor stops, check the E2-02 and E2-03 values on the
“
Modified Parameters/Fault Log
”
screen or the
“ Parameters ” screen again.
4. Make sure that the input data is correct.
When the settings in E2-02 and E2-03 are different than in step 1, the drive set the values automatically.
