Unpacking and ordering a VLT Adjustable
Frequency Drive (AFD)
If you are in doubt as to which VLT AFD you have
received and which options it contains? Use the
following table to find out. The table can also be
used for ordering a VLT 4000 VT.
■
Type code ordering number string
On the basis of your order, the VLT AFD is given an
ordering number that can be seen from the nameplate
on the unit. The number may look as follows:
VLT-4008-V-T4-CN1-ST-R0-DL-F00-A31-C0
This means that the AFD ordered is a VLT 4008 for
three-phase line voltage of 380-460 V (
T4
) in Compact
enclosure NEMA 1 (
CN1-ST
). The hardware variant
is a standard unit without integral RFI filter, (R0). The
AFD features a dis-play unit (
DL
) with no field bus
option card (
F00
), and the 4 relay Card Option (
A31
) .
Character no. 8 (
V
) indicates the application range of
the unit:
V
= Industry dedicated (Variable Torque).
