Table 3.13
shows the number of poles for normal speed
ranges of various motor types. Define motors designed for
other frequencies separately. The motor pole value is
always an even number, because it refers to the total
number of poles, not pairs of poles. The frequency
converter creates the initial setting of
based on
.
P-02 Motor Power [HP]
Range:
Function:
4.00
hp
*
[0.09 -
3000.00 hp]
Enter the nominal motor power in HP
according to the motor nameplate data.
The default value corresponds to the
nominal rated output of the unit. This
parameter is visible in keypad if
is
[1] US
P-03 Motor Current
Range:
Function:
7.20 A
*
[0.10 - 10000.00
A]
Enter the nominal motor current
value from the motor nameplate
data. The data are used for
calculating torque, motor protection
etc.
P-04 Auto Tune
Option:
Function:
NOTE
This parameter cannot be adjusted while
the motor is running.
The Auto Tune function optimises dynamic
motor performance by automatically
optimising the advanced motor parameters
P-04 Auto Tune
Option:
Function:
(
) at motor standstill.
Activate the Auto Tune function by pressing
[Hand] after selecting
[1]
or
[2] Reduced Auto
Tune
. After a normal sequence, the display will
read: "Press [OK] to finish Auto Tune". After
pressing the [OK] key the frequency converter
is ready for operation.

Full Auto
Tune
Performs Auto Tune of the stator resistance R
S
,
the rotor resistance R
r
, the stator leakage
reactance X
1
, the rotor leakage reactance X
2
and the main reactance X
h
. Do
not
select this
option if an LC filter is used between the
frequency converter and the motor.
[2]
Reduced
Auto Tune
Performs a reduced Auto Tune of the stator
resistance R
s
in the system only.
Note:
•
For the best results run Auto Tune on a cold
motor.
•
Auto Tune cannot be performed while the motor
is running.
•
Auto Tune cannot be performed on permanent
magnet motors.
NOTE
It is important to set motor parameters F-04, F-05, and
P-02 to P-08 correctly, since these form part of the Auto
Tune algorithm. An Auto Tune should be performed to
achieve optimum dynamic motor performance. It may take
up to 10 min, depending on the power rating of the
motor.
NOTE
Avoid generating external torque during Auto Tune.
NOTE
If one of the settings in parameters F-04, F-05, or P-02 to
P-08 is changed,
to
, the advanced motor parameters, will return to
default setting.
NOTE
Auto Tune will work problem-free on 1 motor size down,
typically work on 2 motor sizes down, rarely work on 3
sizes down and never work on 4 sizes down. Keep in mind
that the accuracy of the measured motor data will be
poorer when operating on motors smaller than nominal
drive size.
