Installation
■ Connection example VLT 8000 AQUA
The diagram below gives an example of a typical
VLT 8000 AQUA installation.
The mains 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 frequency converter.
An external DC supply can be connected to
terminals 88 and 89.
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 are controlled with
24 V DC. 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 frequency converter can be controlled and
monitored via serial communication.
* These terminals can be programmed for
other functions.
