●
VF separation is usally 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
