• The drive is used in V/f Control and other Auto-Tuning selections are not
possible.
• Drive and motor capacities differ.
• Tunes the drive after the cable between the drive and motor has been replaced
with a cable over 50 m long. Assumes Auto-Tuning has already been
performed.
• Should not be used for any vector control modes unless the motor cable has
changed.
YES
Rotational Auto-Tuning for V/f
Control
T1-01 = 3
• Recommended for applications using Speed Estimation Speed Search or using
the Energy Saving function in
V/f Control.
• Assumes motor can rotate while Auto-Tuning is executed. Increases accuracy
for certain functions like torque compensation, slip compensation, Energy
Saving, and Speed Search.
YES
Table i.17
lists the data that must be entered for Auto-Tuning. Make sure this data is available before starting Auto-Tuning.
The necessary information is usually listed on the motor nameplate or in the motor test report provided by the motor
manufacturer.
