4-32
Full-load Current of motor (PM)
Control mode
FOCPM
Unit: Amper
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.

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.
