●
VF separation is usually applied in induction heating, inverter power supply, torque
motor control, etc.
When VF separation control is selected, the output voltage can be set by the function
code F05.08 or according to the analog, high-speed pulse, PID or communication settings.
For non-digital settings, 100% of each setting corresponds to the rated voltage of the motor.
When the percentage set by the analog output is negative, the set absolute value will be
taken as the valid set value.
F05.07=0: digital setting of VF separation voltage (F05.08)
The VF separation output voltage depends on the digital setting of VF separation
voltage (F05.08).
F05.07=1:AI1
F05.07=2:AI2
F05.07=5: process PID
The VF separation output voltage depends on the process PID function output, as
described in 7.10.
F05.07=6: communication setting
The VF separation output voltage depends on the communication.
If the master-slave communication (F10.05=1) is enabled and the inverter works
as the slave (F10.06=0), the VF separation output voltage is “700FH
(master-slave communication setting) * F01.02 or others (rated voltage of the
motor) * F10.08 (slave receiving proportional coefficient)”. The 700FH data
range is 0.00% to 100.00%, as detailed in Table 0-2.
For general communication (F10.05=0), the VF separation output voltage is
“7006H (voltage setting of the VF separation mode) * F05.08 (digital setting of
