Connection example
The diagram below gives an example of a typical
instal
lation of a VLT frequency converter.
The mains supply is connected to terminals
R/L1/91, S/L2/92 and T/L3/93, while the motor
is conn
ected to U/T1/96, V/T2/97 and W/T3/98.
These numbers can also be seen from the terminals
of the VLT frequency converter.
An ext
ernal DC supply (load sharing) can be
connected to terminals 88 and 89.
Analogue inputs can be connected to terminals 53 [V],
54 [V]
and 60 [mA]. These inputs can be programmed
for either reference, feedback or thermistor. See
Analogue inputs in parameter group 300.
There are 8 digital inputs, which can be connected
to terminals 16-19, 27, 29, 32, 33. These inputs
can be p
rogrammed in accordance with the
table in the Operating instruction. See Digital
inputs in parameter group 300.
There
are two analogue/digital outputs (terminals
42 and 45), which can be programmed to show
the present status or a process value, such as
0-f
max
. Relay outputs 1 and 2 can be used for
giving the present status or a warning.
On terminals 68 (P+) and 69 (N-) RS 485 interface,
the VL
T frequency converter can be controlled and
monitored via serial communication.
Brake terminals 81, 82 and 104-106 are not available
in VLT 6000 and VLT 8000 AQUA series.
