The AI terminals
(
AI1 to AI3
)
of the VDF650 all support the corresponding setting jump
function
,
which fixes the AI input corresponding setting at the jump point when AI input
corresponding setting jumps around the jump range
.
For example
,
AI1 input voltage jumps around 5
.
00 V and the jump range is 4
.
90
–
5
.
10 V
.
AI1 minimum input 0

00 V corresponds to 0

and maximum input 10

00 V corresponds to

The detected AI1 input corresponding setting varies between 49

If you set A6
-
16 to 50
.
0
%
and A6
-
17 to 1
.
0
%,
then the obtained AI1 input corresponding
setting is fxed to 50

eliminating the fuctuation effect

It is used to decide whether to enable point
-
point communication
.
Point
-
point communication indicates direct communication between two or more VDF650
AC drives by using CANlink
.
The master gives target frequency or target torque to one or
multiple slaves according to its own frequency or torque signal
.
If multiple AC drives are connected by using CANlink cards
,
the terminal resistor of the
CANlink card connected to the end AC drive shall be switched on
.
If point
-
point communication is enabled
,
the CANlink communication addresses of the AC
drives are automatically matched without special setting
.
The point
-
point communication rate is set in FD

:
Master
1
:
Slave
0
This parameter is used to determine whether the AC drive is master or slave
.
At point
-
point communication
,
you only need to set the CANlink communication baud rate
.
The communication addresses are allocated automatically based on whether the AC drive is
master or slave
.
