Specification of high-performance vector convertor
When it is selected, communication card must be optional (Modbus RTU, CANlink card, user-
programmable control card, etc.).

Select input channel of given frequency of convertor. There are 10 main reference frequency channels:
0: Digital setting (no memory after power failure)
Value that its set frequency initial value is P0-08 "preset frequency." Through the ▲ ▼ keys (or
multi-function input terminal UP, DOWN) to change the set frequency value.
And when the convertor is power-on after power failure, frequency setting value recovers "digital
setup preset frequency" as the value P0-08.
1: Digital setting (memory after power failure)
Value that its set frequency initial value is P0-08 "presets frequency". By keyboard ▲, ▼ buttons (or
multi-function input terminal UP, DOWN) to change the set frequency value.
And when the convertor is power-on after power failure, the set frequency is the frequency last power
set by keyboard ▲, ▼ keys or terminals UP, DOWN correction is memorized.
It needs to be reminded that P0-23 is "digital setting frequency down memory selection", P0-23 is
used for selecting when the drive is stopped, choose the correction amount or frequency of the
memory. P0-23 is related to downtime, and power-down memory is not related. You need to pay
attention for application.
2: AI1
3: AI2
4: AI3
It means that the frequency is set by analog input terminal to determine. VFD control panel provides
two analog input terminals (AI1, AI2), Optional I / O expansion card provides an additional analog
input terminal (AI3).
Among them, AI1 is 0V ~ 10V voltage input, AI2 can be 0V ~ 10V voltage input, It may also be
4mA ~ 20mA current input. It is selected by J8 jumper on the control panel, AI3 is -10V ~ 10V
voltage input.
Correspondence between the input voltage AI1, AI2, AI3, the target frequency, the user can freely
choose. VFD provides 5 group of correspondence between the curves, including 3 Group curve of
linear relationship (2 point correspondence), 2 group of any 4 points curve correspondence. User
groups can be set via P4 and A6 group function code.
P4-33 function code is used to set AI1 ~ AI3 three-way analog input. Select any cuve in the 5 group,
and then the detailed correspondence of the 5 group of curves please refer to P4 and A6 Group
Function Code instructions.
