Description Of Specific Functions
V800 Series High Performance Closed-Loop Vector Inverter User Manual
FF.4.43 Special function configuration
_ _ _ X: Motor parameter identification auto-start
0: Forbidden
1: Permitted
After modifying the motor nameplate parameters, the inverter will automatically set static self identification of
motor parameters once.
_ _ X _ : Voltage vector composition mode
0: Three-phase composition
1: Two-phase composition
Another modulation method for space voltage vector. This method can help appropriately reduce heating of
the inverter, but audio noise may somewhat increase.
_ X _ _: Small pulse shielding
0: Void
1: Effective
When “Effective” is selected, the heating of the drive can be reduced under full-output voltage.
X _ _ _ : SVC Revolution identification mode/synchro control mode
0: SVC Revolution identification mode 1/synchro id = 0 control mode
1: SVC Revolution identification mode 2 (reserved) effecctive/synchro minimum current control mode
