Chap. 5 FUNCTION CODES
P12 Motor 1 (Rated slip frequency)
P12 specifies rated slip frequency. Obtain the appropriate values from the test report of the motor or by calling the
manufacturer of the motor. Performing auto-tuning automatically sets these parameters.
• Rated slip frequency: Convert the value obtained from the motor manufacturer to Hz using the following expression
and enter the converted value. (
Note: The motor rating given on the nameplate sometimes
shows a larger value.)
(Synchronous speed - Rated speed)
Rated slip frequency (Hz) =
Synchronous speed
× Base frequency
For details about the slip compensation control, refer to the description of F42.
P13 to P15 Motor 1 (Iron loss factors 1 to 3)
P13 to P15 compensates the iron loss caused inside the motor under vector control with speed sensor, in order to
improve the torque control accuracy.
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Basically, there is no need to modify the setting.
P16 to P20
P21 to P23
Motor 1 (Magnetic saturation factors 1 to 5)
Motor 1 (Magnetic saturation extension factors "a" to "c")
These function codes specify the characteristics of the exciting current to generate magnetic flux inside the motor and
the characteristics of the magnetic flux generated.
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Performing auto-tuning while the motor is rotating (P04 = 2 or 3) specifies these factors automatically.
P53, P54 Motor 1 (%X correction factors 1 and 2)
P53 and P54 specify the factors to correct fluctuations of leakage reactance (%X).
Basically, there is no need to modify the setting.
P55 Motor 1 (Torque current under vector control)
P55 specifies the rated torque current under vector control without/with speed sensor.
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Basically, there is no need to modify the setting.
P56 Motor 1 (Induced voltage factor under vector control)
P56 specifies the induced voltage factor under vector control without/with speed sensor.
The combination of P99 (Motor 1 Selection) and P02 (Motor 1, Rated capacity) data determines the standard value.
Basically, there is no need to modify the setting.
P99 Motor 1 Selection
P99 specifies the motor type to be used.
Data for P99 Motor type
0 Motor characteristics 0 (Fuji standard motors, 8-series)
1 Motor characteristics 1 (HP rating motors)
2 Motor characteristics 2 (Fuji motors exclusively designed for vector control)
3 Motor characteristics 3 (Fuji standard motors, 6-series)
4 Other motors
To select the motor drive control or to run the inverter with the integrated automatic control functions such as auto
torque boost and torque calculation monitoring, it is necessary to specify the motor parameters correctly. First select the
motor type with P99 (Motor 1 Selection) from Fuji standard motors 8-series, 6-series, and Fuji motors exclusively
designed for vector control, next specify the motor rated capacity with P02, and then initialize the motor parameters
with H03. This process automatically configures the related motor parameters (P01, P03, P06 through P23, P53 through
P56, and H46).
The data of F09 (Torque Boost 1), H13 (Restart Mode after Momentary Power Failure (Restart time)), and F11
(Electronic Thermal Overload Protection for Motor 1, Overload detection level) depends on the motor capacity, but the
process stated above does not change them. Specify and adjust the data during a test run if needed.
