Pattern Operation (Stage 1 to 7 Rotation Direction, Accelerate/Decelerate Time)
For the pattern operation (acceleration/deceleration time of stage 1 to 7 rotation direction), details are
explained in the section describing the function code C20.
5.4.4 P codes (Motor 1 parameters)
With FRENIC-MEGA, the motor control method can be selected such as V/f control, vector control with/without
speed sensor, and motor control method. To use the integrated automatic control functions such as the auto
torque boost, torque calculation monitoring, auto energy saving operation, torque limiter, automatic deceleration,
auto search, slip compensation, torque vector control, droop control, and overload stop, it is necessary to specify
proper motor constants to build and control the motor model in the inverter. Therefore, it is necessary to correctly
set various constants in addition to the motor capacity and rated current.
The FRENIC-MEGA provides the Fuji-standard motors 8-series, 6-series, and special motor constant for Fuji
vector. To use these Fuji motors, it is enough to set the motor selection (P99). If the cabling between the inverter
and the motor is long (generally, 20 m 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, see "Chapter 4 Operation" in "FRENIC-MEGA Instruction Manual."
When using a motor made by other manufacturers or a Fuji non-standard motor, obtain the test report of the
motor and set the motor constant or perform auto-tuning.
P01
Motor 1 (No. of poles)
Set a number of poles of the motor (write on the motor nameplate). It is used for display of the motor rotation
speed and the speed control. The relationship between the motor rotation speed and the inverter output
frequency is as shown in the following conversion expression.
Motor rotation speed (r/min) = 120/number of poles x frequency (Hz)
- Data setting range: 2 to 22 (poles)
P02
Motor 1 (Capacity)
P02 sets the rated capacity of the motor. Enter the rated value given on the nameplate of the motor.

Data for P02 Unit Function
kW
When P99 (Motor 1 Selection) are 0, 2 to 4
0.01 to 1000
HP
When P99 (Motor 1 Selection) is 1
Change P02 on the key pad. Then, P03, P06 to P23, P53 to P56, and H46 are automatically rewritten.
Please pay close attention.
When P02 is changed from the communication, other function codes are not automatically
re-written.
