Setting
• The drive is used in V/f Control and other Auto-Tuning selections are not

• Tunes the drive after the cable between the drive and motor has been replaced
T1-01 = 2
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.
• Recommended for applications using Speed Estimation Speed Search or using
the Energy Saving function in V/f Control.
T1-01 = 3
• Assumes motor can rotate while Auto-Tuning is executed. Increases accuracy
for certain functions like torque compensation, slip compensation, Energy
Saving, and Speed Search.
