Chapter 4 Parameter SettingsDD Series

Full-load Current of motor (PM)

Unit: Amper

Control mode

FOCPM

 

 

Factory setting: 1.00

 

Settings

(20~120%)*00.01 Amps

This value should be set according to the rated frequency of the motor as indicated on the motor nameplate. The factory setting is 90% X rated current.

Example: If rated current for 400W model is 2.5A. The current range for user will be 0.5~3.0A. (2.5*20%=0.5; 2.5*120%=3.0)

Rated Power of Motor (PM)

Control mode

FOCPM

Factory setting: 0.06

 

Settings

0.00~655.35 kW

 

This parameter sets motor’s rated power. Factory setting will be the drive’s power.

 

Rated Speed of PM Motor (rpm)

Control mode

FOCPM

Factory setting: 250

 

Settings

0~65535

 

This parameter sets motor’s rated speed and it must be set according to the specification shown on the nameplate.

Number of Motor Poles (PM)

Control mode

FOCPM

Factory setting: 16

 

Settings

2~96

 

This parameter sets number of motor poles (odd value is invalid).

 

Rs of Motor parameter (PM)

Control mode

FOCPM

Factory setting: 13.900

 

 

 

Settings

0.0~655.35Ω

 

 

 

 

Ld of Motor Parameter (PM)

 

Control mode

FOCPM

Factory setting: 169.4

 

 

 

Settings

0.0~6553.5mH

 

 

 

 

Lq of Motor Parameter (PM)

 

Control mode

FOCPM

Factory setting: 169.4

 

 

 

Settings

0.0~6553.5mH

 

 

 

 

 

 

 

 

 

Back Electromotive Force (PM)

 

Control mode

FOCPM

Factory setting: 0.0

 

 

 

Settings

0.0~6553.5Vrms

 

This parameter is used to set back electromotive force (phase-phase RMS value) when the motor is operated in the rated speed.

It can get RMS value by Pr.01-00=1 (Motor Auto Tuning)

PG Offset Angle (PM)

Control mode

FOCPM

Factory setting: 360.0

 

Settings

0.0~360.0°

 

This parameter is to measure the PG offset angle of PM motor.
