4.8 Configuring Function Codes for Drive Controls

Fuji non-standard motors, motors of other companies
(1) Selection of PMSM type and pole position detection method
Synchronous motors are categorized into the following types based on the structure of the rotor.
a) Surface magnet assembling magnet on rotor surface (SPM: Surface Permanent Magnet)
b) Buried magnet assembling magnet into rotor iron core (IPM: Interior permanent magnet)
The starting magnetic pole position detection method depends on the motor type. In most cases, the IPMs are
generally used, but the SPMs are sometimes used. Check the specifications with the motor manufacturer before
using synchronous motors.
Set the Initial magnetic position detection mode to the function code P30*. For details, refer to Chapter 5 “5.3.4 P
codes (Motor 1 parameters)”.
If the motor type is unknown, set P30* = 0.
(2) Setting the motor basic constants
To drive other manufacturer’s synchronous motor, set the motor parameters shown in Table 4.8 2 and execute
offline tuning. Check the motor parameters on the motor rating nameplate or consult with the motor manufacturer
before setting them.
Depending on the order, there may be cases where motor constants for synchronous motors are set
individually when the product is shipped. Please note that by initializing data using with H03, motor
constant data will be lost. Record the motor constants prior to initialization.
Set motor constants after selecting sensorless vector control with F42* = 15.
Set the motor constants shown in the following table. The setting values are determined by the values on the motor
nameplate and machine specifications. Check the nameplate values and machine specifications beforehand.
