The drive is able to perform either a stationary or a rotating autotune. The motor must be at a
standstill before an autotune is enabled. A rotating autotune should be used whenever possible
so the measured value of power factor of the motor is used by the drive.
WARNING
• A stationary autotune can be used when the motor is loaded and it is not possible to
uncouple the load from the motor shaft. A stationary autotune measures the stator
resistance of the motor and the voltage offset in the drive. These are required for good
Autotune
performance in vector control modes. A stationary autotune does not measure the power
factor of the motor so the value on the motor nameplate must be entered into Pr 0.43.
• A rotating autotune should only be used if the motor is uncoupled. A rotating autotune first
performs a stationary autotune before rotating the motor at
selected. The rotating autotune measures the power factor of the motor.
To perform an autotune:
• Set Pr 0.40 = 1 for a stationary autotune or set Pr 0.40 = 2 for a rotating autotune
• Close the Drive Enable signal (terminal 31). The drive will display 'rdY'.
• Close the run signal (terminal 26 or 27). The lower display will flash 'Auto' and 'tunE'
alternatively, while the drive is performing the autotune.
• Wait for the drive to display 'rdY' or 'inh' and for the motor to come to a standstill.
If the drive trips, see Chapter 13 Diagnostics on page 242.

A rotating autotune will cause the motor to accelerate up to
direction selected regardless of the reference provided. Once complete the motor
will coast to a stop. The enable signal must be removed before the drive can be
made to run at the required reference.
The drive can be stopped at any time by removing the run signal or removing the
drive enable.
