Before power-up
• The drive enable signal is not given (terminal 11)
• Run signal is not given
Verify that RFC-A mode is displayed as the drive powers up.
If the mode is incorrect see section 5.6 Changing the operating mode on page 75.

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 stationary autotune will give moderate performance whereas a rotating autotune will
give improved performance as it measures the actual values of the motor parameters required by the drive.
A rotating autotune will cause the motor to accelerate up to
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.
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. The stationary autotune measures the stator resistance and transient inductance of
the motor. These are used to calculate the current loop gains, and at the end of the test the values in
Pr 04.013 and Pr 04.014 are updated. A stationary autotune does not measure the power factor of the
Autotune
motor so the value on the motor nameplate must be entered into Pr 00.009.
• 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
autotune measures the stator inductance of the motor and calculates the power factor.
To perform an autotune:
• Set Pr 00.038 = 1 for a stationary autotune or set Pr 00.038 = 2 for a rotating autotune
• Close the drive enable signal (apply +24 V to terminal 11). The drive will display 'rdy'.
• Close the run signal (apply +24 V to terminal 12 or 13). The display will flash 'tuning' while the drive is
performing the autotune.
• Wait for the drive to display 'inh' and for the motor to come to a standstill
If the drive trips, see Chapter 12 Diagnostics on page 179.
• Remove the drive enable and run signal from the drive.
