.
2
)
Control of asynchronous motor and PMSM
It supports vector control of three
-
phase AC asynchronous motor and three
-
phase AC
PMSM
.
3
)
Diversifed control modes
It supports three control modes
,
namely

)
User programmable function
The VDF65PC1 programmable card enables you to write programs in ladder diagram
.
Its programming environment is compatible with that of the H1U series PLC
.
8
)
Advanced background software
The background monitoring software helps to achieve functions of parameter upload
&
download and a real
-
time oscilloscope
.

)
Other new functions
The newly added functions of the VDF650 series AC drive are described as below
:
Function Description
Virtual I
/
O It can implement various simple logic functions
.
Motor overheat protection
The optional VDF65IO1 extension card enables AI3 to
receive the signal from the motor temperature sensor
input
(
PT100
,
PT1000
)
thereby providing motor overheat
protection
.
Rapid current limit
It helps to avoid frequent occurrence of overcurrent faults
of the AC drive
.
