4.8 Configuring Function Codes for Drive Controls
4-16
[ 4 ] Driving a non-Fuji motor or Fuji non-dedicated IM under vector control with/without
speed sensor
(1) Configuring the function codes of motor parameters
When “driving under vector control with speed sensor (F42* = 6)” or “vector control without speed sensor (dynamic
torque vector, F42* = 1)”, it is necessary to set the motor parameters.
Execute auto tuning when driving non-Fuji or Fuji non-dedicated vector motor (non-VG motor) under “vector control
(F42*=6) with speed sensor” or any motor under “vector control without speed sensor (dynamic torque vector) (F42*
= 1)”.
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.
Execute auto tuning after setting values and initializing the motor (H03=2).

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 P13*, P16* to P20*, P53*, P55*, and H46.
･
If the motor is used under vector control with speed sensor, it is recommended to use the dedicated
motor whose rated voltage is designed to be lower than the power voltage.
･
If the general-purpose motor is used under vector control, the rated voltage (base frequency voltage)
becomes equal to the input voltage and there is no voltage margin to control with vector control. This
might increase the motor current exceeding the rating current and might occur the motor overheat or
overload trip.
After the above configuration, initialize motor 1 with the function code (H03 = 2). It automatically updates
the motor parameters P01*, P03*, P06* to P13*, P16* to P20*, P53*, P55*, and H46.
