5.3 Description of Function Codes

5.3.4 P codes (Motor 1 parameters)
To use the integrated automatic control functions such as auto torque boost, torque calculation monitoring, auto
energy saving operation, torque limiter, automatic deceleration (anti-regenerative control), auto search for idling
motor speed, slip compensation, vector control without speed sensor (torque vector), droop control, and overload
stop, it is necessary to build a motor model in the inverter by specifying proper motor parameters including the
motor capacity and rated current.
The FRENIC-Ace, provides built-in motor parameters for Fuji standard motors 8-series. To use these Fuji motors, it
is enough to specify motor parameters for P99 (Motor 1 selection). If the cabling between the inverter and the
motor is long (generally, 20 m (66 ft) or longer) or a reactor is inserted between the motor and the inverter, however,
the apparent motor parameters are different from the actual ones, so auto-tuning or other adjustments are
necessary.
For the auto-tuning procedure, refer to the FRENIC-Ace Instruction Manual, Chapter 4 “TEST RUN
PROCEDURE.”
When using a motor made by other manufacturers or a Fuji non-standard motor, obtain the datasheet of the motor
and specify the motor parameters manually or perform auto-tuning.
P01 Motor 1 (No. of poles)
P01 specifies the number of poles of the motor. Enter the value given on the nameplate of the motor. This setting is
used to display the motor speed on the LED monitor and to control the speed (refer to E43). The following
expression is used for the conversion.
Motor rotational speed (min
-1
) = 120/No.of poles x Frequency (Hz)
• Data setting range: 2 to 22 (poles)
P02 Motor 1 (Rated capacity)
P02 specifies the rated capacity of the motor. Enter the rated value given on the nameplate of the motor.
P02 data Unit Function
0.01 to 1000
kW When P99 (Motor 1 selection) = 0, 4, 20 or 21
HP When P99 (Motor 1 selection) = 1
When accessing P02 with the keypad, take into account that the P02 data automatically updates data of P03, P06
through P13, P53 and H46.
P03 Motor 1 (Rated current)
P03 specifies the rated current of the motor. Enter the rated value given on the nameplate of the motor.
• Data setting range: 0.00 to 2000 (A)
