Axor Microspeed 12 - Microspeed EMC Requirements and Assembly

MICROSPEED
14
REV 04/05
The regulated standard in accordance with conformity of
electromagnetic is summarized in Regulation CEI EN 61800
(complete).
Microspeed conformity is assured only if it is installed
following the precise assembly criteria expressed below.
The fundamental assembly characteristics are summarized
bolow:
-- Use of appropriate network to filter the line (transformer
input), from disturbances conducted or produced by the
drive.
A series of filters released by AXOR are available for this
purpose.
-- Use of shielded cables, both for power connection (to
the transformer and the motor), and for signal connection
(also to the controller).
-- Using the division of cables technique. Separate power
cables from signal cables.
-- The correct ground connection of predisposed parts.
-- It is important that the drive's ground connections are as
short as possible and no longer than 8 inches (20 cm).
The figure shows the connection using terminals fixed to
the drive's base (bottom). This connection also reduces
disturbances in the net.
--The Motor ground cable has to be external (not inserted
in a multipolar cable) with minimun section 1.5 mmq (0,059
square inch).
