4.8 Configuring Function Codes for Drive Controls

[ 3 ] If running the motor with V/f control with slip compensation, dynamic torque vector
control, or sensorless vector control
Configuring the function codes of motor parameters
If using “V/f control with slip compensation (F42* = 2)”, “Dynamic torque vector control (F42* = 1”, or “Sensorless
vector control (F42* = 5)”, 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””.

increase values so that they are longer

(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.
(3) Performing tuning
Even for Fuji standard motors, be sure to perform tuning if using sensorless vector control.
Perform tuning in accordance with the “4.8.1 [ 5 ] Induction motor tuning method”.
