3. Function Explanation
2
■
P01 Number of motor 1 poles
This function sets the number of poles of motor 1 to be driven.
If this setting is not made, an incorrect motor speed (synchro-
nous speed) is displayed on the LED.
- Set values: 2, 4, 6, 8, 10, 12, 14
■
P02 Motor 1 (Capacity)
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:
Models with nominal applied motor of 30HP or less: 0.01
to 45kW
Models with nominal applied motor of 40HP or more: 0.01
to 500kW
• Set the nominal applied motor capacity listed in “Standard
Specifications” in Chapter 1. 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 regarding 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 setting)
P08 Motor 1 (% X1 setting)
NOTE:
The set values for the FUJI standard 3-phase motor are 200V, 50Hz, 4
poles for the 230V; 400V, 50Hz, 4 poles for the 460V.
■
P03 Motor 1 (Rated current)
This function sets the rated current value of motor 1.
- Set value : 0.00 to 2000A
■
P04 Motor 1 (Tuning)
This function measures and automatically writes motor data.
3.4 Motor Parameters
P01 M1 POLES
P03 M1-Ir
P02 M1-CAP
P04 M1 TUN1
Perform “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. 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 frequency
1,” “F04 Base frequency 1,” “F05 Rated voltage 1,” and
“F06 Maximum voltage 1.”
2. Enter untunable motor constants first. Set functions “P02
Capacity,” “P03 Rated current,” and “P06 No-load current,”
(input of no-load current is not required when P04=2,
running the motor at tuning, is selected).
3. When tuning the no-load current, disconnect the motor
from the load machine, and beware of motor rotation.
4. Set 1 (motor stop) or 2 (motor rotation) to function “P04
Tuning.” Press the
FUNC
DATA
key to write the set value and
press the
FWD
key or
REV
key, then start tuning
simultaneously.
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, the no-load
current is tuned and decelerates according to the decelera-
tion time, the total tuning time varies depending on set
acceleration and deceleration times.)
5. Press the
STOP
key after the turning is completed.
6. End of procedure
NOTE:
Use function “A13 Motor 2 (Tuning),” to tune motor 2. In this case,
functions described in 1. and 2. above are for the function (A01 - ) of
motor 2.
Set value Operation
0 Inactive
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.
Tuning procedure
WARNING
When the tuning value is set to
2, the motor rotates at a
maximum of half the base
frequency. Disconnect the
motor from the load machine
and beware of motor rotation.
