This function sets the number of poles of motor 1 to be
driven. If this setting is not made, an incorrect motor
speed (synchronous speed) is displayed on the LED.
Set values: 2, 4, 6, 8, 10, 12, 14
The nominal applied motor capacity is set at the factory.
The setting should be changed when driving a motor with
a different capacity.
Set value for models with nominal applied motor of 30HP or less
: 0.01 to 60HP
Models with nominal applied motor of 40HP or more
: 0.01 to 800HP
Set the nominal applied motor capacity listed in 9-1,
"Standard Specifications." Also set a value in the range
from two ranks lower to one rank higher than the nominal
applied motor capacity. When a value outside this
range is set, accurate control cannot be guaranteed. If
a value between two nominal applied motor capacities is
set, data for the lower capacity is automatically written for
related function data.
When the setting of this function is changed, the values
of the following related functions are automatically set to
data of the FUJI 3-phase standard motor.
-- P03 Motor 1 (rated current)
-- P06 Motor 1 (no-load current)
-- P07 Motor 1 (% R1)
-- P08 Motor 1 (% X1)
Note:
The set values for the FUJI 3-phase standard motor are
230V, 50Hz, 4 poles for the 230V series; 460V, 50Hz, 4
poles for the 460V series.
This function sets the rated current value of motor 1.
Setting range: 0.00 to 2,000A
This function measures and automatically writes motor
data.

Operation

1
Measure the primary resistance (%R1) of the
motor and leakage reactance (%X) of the base
frequency when the motor is stopping and
automatically write both values in P07 and
P08.
2
Measure the primary resistance (%R1) of the
motor and leakage reactance (%X) of the base
frequency when the motor is stopping,
measure the no-load current (lo) when the
motor is running, and automatically write these
values in P06, P07, and P08.
Put the motor into the state unit separating
from the machine for the tuning of the no-load
current.
In the state that the load is connected, cannot
the tuning correctly. Execute the auto tuning of
set value “1" after obtaining the test report etc.
from the motor manufactures when not making
it in the state of the motor unit, and setting P06
(no-load current) beforehand.
Perform auto tuning when data written beforehand in
"P06 No-load current," "P07 %R1," and "P08 %X," differs
from actual motor data. Typical cases are listed below.
Auto tuning improves control and calculation accuracy.
・When a motor other than the FUJI standard 3-phase
motor is used and accurate data is required for close
control.
・When output-side impedance cannot be ignored as
when cable between the inverter and the motor is too
long or when a reactor is connected.
・ When %R1 or %X is unknown as when a non-standard
or special motor is used.
1. Adjust the voltage and frequency according to motor
characteristics. Adjust functions "F03 Maximum output
frequency," "F04 Base frequency," "F05 Rated voltage,"
and "F06 Maximum output voltage."
2. Enter untunable motor constants first. Set functions
"P02 Capacity," "P03 Rated current," and "P06 No-load
current," (input of no-load current not required when
P04=2, for running the motor at tuning, is selected).
3. When tuning the no-load current, beware of motor rotation.
4. Set 1 (motor stop) or 2 (motor rotation) to function "P04
Auto tuning." Press the key to write the set
value and press the key or key then
start tuning simultaneously.
5. Tuning takes several seconds to several tens of seconds
(when 2 is set. As the motor accelerates up to half the
base frequency according to acceleration time, is tuned
for the no-load current, and decelerates according to the
deceleration time, the total tuning time varies depending
on set acceleration and deceleration times.)
6. Press the key after the tuning is completed .
7. End of procedure.
