Motor
thermistor
set-up

The motor thermistor connection is made through the drive encoder port
(terminal 15). The thermistor type is selected in

P1 Thermistor Type

(03.118).

Autotune

The drive is able to perform either a stationary or a rotating auto-tune.
The motor must be at a standstill before an auto-tune is enabled. A
stationary auto-tune will give moderate performance whereas a rotating
auto-tune will give improved performance as it measures the actual
values of the motor parameters required by the drive.

•

A stationary auto-tune can be used when the motor is loaded and it
is not possible to uncouple the load from the motor shaft. The
stationary auto-tune 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

00.038

and Pr

00.039

are updated. A stationary auto-tune does not measure the

power factor of the motor so the value on the motor nameplate must
be entered into Pr

00.043

.

•

A rotating auto-tune should only be used if the motor is uncoupled.
A rotating auto-tune first performs a stationary auto-tune before
rotating the motor at

2

/

3

base speed in the direction selected. The

rotating auto-tune measures the stator inductance of the motor and
calculates the power factor.

To perform an auto-tune:

•

Set Pr

00.040

= 1 for a stationary auto-tune or set Pr

00.040

= 2 for

a rotating auto-tune

•

Close the drive enable signal (terminal 11 and 13). The drive will
display ’Ready’.

•

Close the run signal (terminal 7 or 8). The lower display will flash
‘Autotune’ while the drive is performing the auto-tune.

•

Wait for the drive to display ’Ready’ or ‘Inhibit’ and for the motor to
come to a standstill

•

Remove the drive enable and run signal from the drive.

Save
parameters

Select 'Save Parameters' in Pr

mm.000

(alternatively enter a value of

1000 in Pr

mm.000

) and press red

reset button or toggle the reset

digital input.

Run

Drive is now ready to run

Action

Detail

A rotating auto-tune 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.
