This procedure must be done only by qualified personel which are familiar with drives. if
you need more information contact axor.
a)
power off
all the supplies of the electrical box.
b) Verify:
the
drive-motor coupling
the stall current (I
o
) of the motor should be equal to/or greater
than the nominal output current of the drive;
the
positioning
of the drive into the electrical box;
the
pollution level
and the
ventilation
;
the
connection to earth
of the electrical box where the drive is installed (see "2.5 Connection
to ground and earth").
c) Execute the wiring following this order, avoiding that wiring's pieces, cables, wires, screws, conduc-
tive objects, etc. do not enter into the drive through its slits:
1- First connect
earth
.
2- Connect the
cables for the motor's power
(U, V, W) and the
filter
3x1.2mh
, if the cable
length is greater than 20/25m.
3- Connect the
earth
of the motor's power
(PE) and, if necessary, connect the cables of the
electromechanical
brake
.
4- Connect the
external shield
of the motor's cable: it must be shielded utilising a u-clamp to
the zinced panel of the electrical box (see "2.6 Note about cable shielding").
5- If an
external
braking resistor
is used, connect it between pins +R and -R
by using a cable
as short as possible. If the cable length is greater than 20/30 cm, the cable must be twisted and
shielded, besides the shield must be connected to ground on both ends utilising u-clamps to the
zinced panel of the electrical box.
6- Connect the motor's feedback cable to the drive's
j1
connector
7- Connect the
main power supply cable
(L1-L2-L3) and the
earth cable
(PE).
always insert a power relay or a thermal magnet on every phase of the products power
supply.
(for single phase power supply use l1 and l2.)
8- Connect the
auxiliary supply cable
(+24V).
Use an external power supply, that must be stabilized and galvanically isolated from the main
supply.
9- Connect the PC to the drive utilising the
Rs232
cable.
10- Supply the drive with the
auxiliary supply
and then
main supply
following the
procedure
illustrated at the end of the chapter.
11- Open the
Speeder One
interface.
12- Execute the tests on the drive and the motor.
In the following page there is an
example of a basic connection
.
