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! Injury to Personnel. 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.
• Before you do Rotational Auto-Tuning to prevent drive malfunction, uncouple the motor from the load. 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 procedure 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, examine the values of E2-02 and E2-03 again in the Verify Menu or Parameter Setting
Mode.
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.
■ Precautions before Stationary Auto-Tuning for Line-to-Line Resistance and Stator
Resistance Auto-Tuning
In V/f control, when the motor cable is 50 meters (164 feet) or longer, do Stationary Auto-Tuning for Line-to-Line
Resistance.
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 Using Deceleration Rate Tuning and KEB Tuning
Before Deceleration Rate Tuning or KEB Tuning, check these items:
