Motor 1 (P: Motor Parameters)

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 (synchronous speed) is displayed on the LED.

	P	0	1	M	1		P	O	L	E	S
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.

P 0 2 M 1 - C A P

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.

P03 Motor 1 (rated current)

‹This function sets the rated current value of motor 1.

P 0 3 M 1 - I r

Setting range: 0.00 to 2,000A

P04 Motor 1 (Tuning)

‹This function measures and automatically writes motor data.

1Measure 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.

2Measure 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.

Tuning procedure

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 FUNC key to write the set

value and press the	FWD	key	or	REV	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 STOP

7.End of procedure.
