This diagram shows a typical installation
of the VLT® AutomationDrive. Power
is connected to the terminals 91 (L1),
92 (L2) and 93 (L3) and the motor is
connected to 96 (U), 97 (V) and 98 (W).
Terminals 88 and 89 are used for load
sharing between drives.
Analog inputs can be connected to
the 53 (V or mA), and for 54 (V or mA)
terminals.

These inputs can be set up as either
reference, feedback or thermistor
inputs.
There are 6 digital inputs to be
connected to terminals 18, 19, 27, 29,
32, and 33. Two digital input/output
terminals (27 and 29) can be set up
as digital outputs to show an actual
status or warning or can be used as a
pulse reference signal. The terminal 42
analog output can show process
values such as 0 - Imax.
