Note: output voltage F1005: is set by reference voltage. When the voltage command is too large while the
potentiometer is at maximum limit, please decrease the F1005.
② Complete separation (F1002=40 & F2001=2)
Use the reference voltage (F1005) in V/f pattern as the maximum value, gain this voltage command through the
external control terminal "VIF1" inputs (0~10V) and use it as the output voltage command of the inverter. The
frequency command and voltage command are totally separated from each other.
The relationships between VIF1 voltage input and gain coefficient are as follows:
Gain coefficient (linear function)
VIF1=0V input，
VIF1=5V input，
VIF1=10V input，
Note 1: this function is noneffective during DC braking.
Note 2: AVR functions which are accorded to reference voltage (F1005 data) are effective.
Note 3: Even though the settings of instability elimination (F1308) are effective, the performance of frequency and
voltage commands from this function are reduced.
Note 4: The bias and gain of VIF1 voltage coefficient are set to be noneffective.
Note 5: The frequency and voltage commands are unattached, therefore, for the output frequency, the motor may
over-excited when the voltage command is too large, and the inverter may trip off because of over current.
Please pay attention to the settings of frequency and voltage commands. (Especially during the acceleration/
deceleration actions)
