Before power-up
Ensure:
•
The drive enable signal is not given (terminal 11)
•
Run signal is not given
•
Motor is connected
Power-up the drive
Ensure:
•
Drive displays ‘inh’
If the drive trips, see Chapter 11

= FAST. Also
ensure Pr

are set correctly, otherwise premature ‘It.br’ trips
may be seen).
Autotune
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.
•
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 dead time compensation for the drive. These are required for good 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
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
2
/
3
base speed in the direction selected. The
rotating autotune measures the power factor of the motor.
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 11
•
Remove the drive enable and run signal from the drive.

A rotating autotune will cause the motor to accelerate up to
2
/
3
base speed in the 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.
