4.8 Configuring Function Codes for Drive Controls
4-20
[ 4 ] If running the motor with dynamic torque vector control with sensor or vector
control with sensor
Configuring the function codes concerning a PG (pulse generator) and PG signals
If running the motor with “Dynamic torque vector control with sensor (F42* = 4)” or “Vector control with sensor
(F42* = 6)”, it is necessary to set function codes corresponding to the PG (encoder) specification.
Set function codes in accordance with “4.8.1 [ 2 ] If running the motor with V/f control with sensor -
Configuring the function codes concerning a PG (pulse generator) and PG signals”.
Configuring the function codes of motor parameters
If using “Dynamic torque vector control with sensor (F42* = 4)” or “Vector control with sensor (F42* = 6)”, it is
necessary to set the basic function codes below.
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
Setting””.

(2) Initializing motor constants
After setting the basic motor constants, initialize (H03 = 2) motor 1 with the function code H03.
Necessary motor constant related function codes are automatically set. Refer to Chapter 5 "5.3.5 H codes (High
performance functions)" for details.
Changing P02* will automatically change P03*, P06* to P13*, P16* to P20*, P53*, P55*, P56*, and H46,
and therefore caution is advised.
Even for Fuji standard motors, perform tuning in such cases as when the length of wiring between the
inverter and motor is long (generally 20 m (65.6 ft) or more), or if connecting a reactor between the
inverter and motor.
