Connection example, VLT 4000 VT
The diagram below gives an example of a typical
VLT 4000 VT installation.
The line supply is connected to terminals 91 (L1),
92 (L2) and 93 (L3), while the motor is connected to
96 (U), 97 (V) and 98 (W). These numbers can also
be seen from the terminals of the VLT AFD.
An external DC supply can be connected to terminals
88 and 89 (VLT 4006-4072, 200-240V and VLT
4016-4302, 460V, VLT 4016-4300, 600 V).
Analog 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
Analog 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 programmed in accordance with the table
in
Inputs and outputs 300-328
.
There are two analog/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 VLT AFD can be controlled and monitored
via serial communication.
* These terminals can be programmed for
other functions.
