4.8.2 Driving a permanent magnet synchronous motor (PMSM) without pole sensor
and magnetic pole position sensor
■ Selection of PMSM type and pole position detection method
The permanent magnet type synchronous motor is classified as follows depending on the rotor structure (magnet
layout):
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 IPMPMs are generally used, but the SPMSMs are sometimes used. Consult with the motor
manufacturer before use. 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.
[ 1 ] Driving a non-Fuji PMSM
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.
There is the case that the customer's order, the motor parameters have been set at the factory. Please
note that you do data initialized using the H03, motor parameters will be lost.
Before initialization, record
the data to be changed to memorize the motor constant.
(1) Configuring the function codes of motor parameters
When driving PMSM without speed sensor and magnetic pole position sensor, set the motor parameters after
selecting F42=15.
Configure the function codes listed Table 4.8-2 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
