2: AI2
The V/f separation voltage is input with current or voltage signals through the AI2 terminal. The
frequency is calculated according to the preset AI curve.
3: AI3
The V/f separation voltage is input with current or voltage signals through the AI3 terminal. The
frequency is calculated according to the preset AI curve. The AC drive has two AI terminals by default,
and the AI3 terminal needs to be provided through the I/O extension card.
5: Multi-reference
In multi-reference mode, different combinations of DI terminal states correspond to different
reference values. The four multi-reference terminals can provide 16 state combinations,
corresponding to 16 reference values (percentage x maximum frequency) of parameters in group FC.
6: Simple PLC
The V/f separation voltage is set by simple PLC. For details, see the function description of simple
PLC.
7: PID
The V/f separation voltage is set by PID. For details, see the PID function description.
9: Communication
The main frequency is set through communication. The running frequency is input through remote
communication. The AC drive must be equipped with a communication card to implement
communication with the host controller. This mode applies to remote control or centralized control
systems of multiple equipment.
F3-14
Voltage digital setting for V/f separation
Address:
62222
Min.:
0
Unit:
V
Max.: 65535 Data type: UInt16
Default:
0
Change:
At once
Value Range:
0 V to 65535 V
Description
The reference value is between 0 V and the rated voltage. In V/f half separation mode, the output
voltage is twice the reference value.
F3-15
Voltage rise time of V/f separation
Address:
62223
Min.:
0.0
Unit:
s
Max.: 1000.0 Data type: UInt16
Default:
0.0
Change:
At once
Value Range:
0.0s to 1000.0s
Description
This parameter defines the time required for the output voltage to rise from 0 to the rated motor
voltage. In V/f half separation mode, this parameter is invalid, and the voltage rise time is the same as
that set by F0-17.
F3-16
Voltage fall time of V/f separation
Address:
62224
Min.:
0.0
Unit:
s
Max.: 1000.0 Data type: UInt16
Default:
0.0
