*1 A terminal to which H2-xx = 3 [H2-xx: MFDO Function Select = Fault] is assigned functions the same as during usual operation.
WARNING! Crush Hazard. Make sure that the holding brake does not open during Stationary Auto-Tuning for Line-to-Line
Resistance with the machine connected to the motor. Wire the sequence to prevent a multi-function output terminal to open the
holding brake during Auto-Tuning. Failure to obey can cause damage to the machine or personal injury.
WARNING! Sudden Movement Hazard. Disconnect the load from the motor for Rotational Auto-Tuning. Failure to obey could
cause death or serious injury and cause damage to the machine.
WARNING! Crush Hazard. Rotational Auto-Tuning rotates the motor at a frequency that is 50% or more of the rated frequency
of the motor. Make sure that there are no issues related to safety in the area around the drive and motor. Failure to obey can
cause death or serious injury and damage to machinery.
NOTICE: Crush Hazard. When executing 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. If PM Rotational
Auto-Tuning is performed, the motor will remain stopped for approximately one minute with power applied and then the motor
will rotate for one minute.
■
Precautions before Rotational Auto-Tuning
WARNING! Electrical Shock Hazard. In Rotational Auto-Tuning, the drive applies voltage to the motor before the motor rotates.
Do not touch the motor until Auto-Tuning is complete. Failure to obey could cause serious injury.
• 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. In Stationary Auto-Tuning, the drive applies voltage to the motor. Do not touch the motor
until Auto-Tuning is complete. Failure to obey could cause serious injury.
Automatically Set Mot Rated Slip and Mot 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 [Mot Rated Slip] and E2-03 [Mot No-Load Current] after Auto-Tuning is complete when
you use the motor for the first time in Drive Mode.
