4.8.1 Driving an Induction Motor (IM)
[ 1 ] Driving a non-Fuji motor or Fuji non-standard IM under the V/f control
(1) Configuring the function codes of motor parameters
Under the V/f control (F42* = 0 or 2), any of the following cases requires configuring the basic function codes given
below and auto-tuning.
- 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 design values of the machine . For the
motor ratings, check the ratings printed on the motor's nameplate. For design values of the machine, ask system
integrators or machine manufacturers about them.
For details on how to modify the function code data, see Chapter 3 “3.4.1 Setting up function codes “Data

longer than your machine design values. If the specified time is
short, the inverter may not run the motor properly.
