4.5 Auto-Tuning for Drive and Motor Parameters
The Auto-Tuning function automatically sets motor parameters for optimum performance. The drive must
be connected for DriveWizard Plus to perform Auto-Tuning, and certain information regarding the type of
motor needs to be entered manually.
WARNING
Proper precautions must be taken when performing Rotational Auto-Tuning.
Be sure to read the instruction manual thoroughly, paying particular attention to the following
points:
・ Make sure that the motor has been decoupled from the load when performing
Rotational Auto-Tuning. The motor should also be properly installed to a secure base.
Any motor keys or other loose parts should be removed from the area to prevent
accidents that may result when the motor begins to rotate.
・ Clear the area around the motor.
WARNING
Proper precautions must be taken when performing Auto-Tuning for Energy Saving.
Read the instruction manual thoroughly, paying particular attention to the following points:
・ Make sure that the motor has been decoupled from the load when performing Auto-
Tuning for Energy Saving. The motor should also be properly installed to a secure base.
Any motor keys or other loose parts should be removed from the area to prevent
accidents that may result when the motor begins to rotate.
・ Clear the area around the motor.
WARNING
Although the motor does not rotate during Stationary Auto-Tuning, current still flows from the
drive into the motor.
Be sure to read the instruction manual thoroughly, paying particular attention to the following
points:
・ Although the motor does not rotate during Stationary Auto-Tuning, current still flows
from the drive into the motor. Refrain from touching the motor until the Auto-Tuning
process is complete.
・ A holding brake (if used) should not be closed during Stationary Auto-Tuning.
・ Stationary Auto-Tuning collects motor data automatically, and requires that the load be
set to no more than 50% of the rated load for the motor.
WARNING
Although the motor does not rotate during Auto-Tuning for Resistance Between Lines,
current still flows through from the drive into the motor.
Be sure to read the instruction manual thoroughly, paying particular attention to the following
points:
・ Although the motor does not rotate during Auto-Tuning for Resistance Between Lines,
current still flows from the drive into the motor. Refrain from touching the motor until the
Auto-Tuning process is complete.
・ A holding brake (if used) should not be closed during Auto-Tuning for Resistance
Between Lines.
