Chapter 4 Description of Parameters | VFD-VJ
4-41
stator’s phase inductance(Ld) of the synchronous motor
stator’s phase inductance(Lq) of the synchronous motor
Control mode
FOCPM
Factory setting: 0.00
Settings 0.0~655.35mH
Enter the synchronous motor’s phase inductance. For surface type magnets (SPM), Ld = Lq; for built-in
magnets (IPM), Ld ≠ Lq.
Back EMF of the synchronous motor
Control mode
FOCPM
Factory setting: 0
Settings 0~65535 V/krpm
Enter the back EMF of the synchronous motor.
Encoder type selection
Control mode
FOCPM
Factory setting: 3
Settings 3: Resolver
PG Offset angle of synchronous motor
Control mode
FOCPM
Factory setting: 0.0
Settings 0.0～360.0°
Offset angle of the PG origin for the synchronous motor.
Number of poles of the resolver
Control mode
FOCPM
Factory setting: 1
Settings 1~5
Encoder Pulse
Control mode
FOCPG FOCPM
Factory setting: 1024
Settings 1~20000
This parameter can be set the encoder's number of pulses per revolution (PPR).
