Fuji Electric FRENIC-MEGA - Function Code Basic Settings and Tuning < 6

4-12
4.1.10 Function code basic settings < 5 >
Driving a Fuji general-purpose motor under V/f control with speed sensor (F42* = 3) or dynamic torque vector control with
speed sensor (F42* = 4) requires configuring the following basic function codes. (Refer to Figure 4.1 on page 4-1.)
Select Fuji standard 8- or 6-series motors with the function code P99*.
Configure the function codes listed below according to the motor ratings and your machinery design values. For the motor
ratings, check the ratings printed on the motor's nameplate. For your machinery design values, ask system designers about
them.

After the above configuration, initialize motor 1 with the function code (H03 = 2). It automatically updates the motor
parameters P01*, P03*, P06* to P23*, P53* to P56*, and H46.
When accessing the function code P02*, take into account that changing the P02* data automatically updates the data
of the function codes P03*, P06* to P23*, P53* to P56*, and H46.
The motor rating should be specified properly when performing auto-torque boost, torque calculation monitoring,
auto energy saving, torque limiting, automatic deceleration (anti-regenerative control), auto search for idling moto
r
speed, slip compensation, torque vector control, droop control, or overload stop.
In any of the following cases, the full control performance may not be obtained from the inverter because the moto
r
parameters differ from the factory defaults, so perform auto-tuning. (Refer to Section 4.1.7.)
• The motor to be driven is not a Fuji product or is a non-standard product.
• The wiring distance between the inverter and the motor is too long (generally 20 m or more).
• A reactor is inserted between the inverter and the motor.
4.1.11 Function code basic settings and tuning < 6 >
Under V/f control with speed sensor (F42* = 3) or dynamic torque vector control with speed sensor (F42* = 4), any of the
following cases requires configuring the basic function codes given below and auto-tuning. (Refer to Figure 4.1 on page 4-1.)
- Driving a non-Fuji motor or non-standard motor
- Driving a Fuji general-purpose motor, provided that the wiring distance between the inverter and motor is long or a reactor is
connected
Configure the function codes listed below according to the motor ratings and your machinery design values. For the motor
ratings, check the ratings printed on the motor's nameplate. For your machinery design values, ask system designers about
them.
