WARNING
• The motor must be uncoupled from the load before attempting this
autotune.
• The normal low speed test will rotate the motor by up to 2 rotations
in the direction selected and the drive measures the encoder phase
angle and updates the value in Pr 3.25. This test also measures the
Autotune
stator resistance, and inductance of the motor. These are used to
calculate the current loop gains, and at the end of the test the values
in Pr 0.38 and Pr 0.39 are updated. This test takes approximately
20s to complete.
To perform an autotune:
• Set Pr 0.40 = 2
• Close the run signal (terminal 26 or 27).
• Close the Drive Enable signal (terminal 31). The lower display will
flash 'Auto' and 'tunE' alternatively, while the drive is performing the
test.
• Wait for the drive to display 'rdy' or 'inh', and for the motor to come
to a standstill.
If the drive trips, see Chapter 9 Diagnostics on page 45.
Remove the drive enable and run signal from the drive.
Enter 1000 in Pr xx.00

Installation Started
The normal low speed test will rotate the motor by up to 2
revolutions in the direction selected, regardless of the
reference provided. Once complete the motor will come to a
standstill. The run 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.
