2.1
The drives have to be supplied from an isolating rectified transformer secondary or a DC
isolated power supply.
The conformity is assured only if it is installed following the precise assembly criteria
expressed below. The fundamental assembly characteristics are summarized below:
A) Use of appropriate network to filter the line (transformer input), from disturbances
conducted or produced by the drive. (series of filters released are available for this purpose)
B) Use of shielded cables, both for power connection (to the transformer and the motor),
and for signal connection (also to the controller).
C) Using the division of cables technique. Separate power cables from signal cables.
D) The correct ground connection of predisposed parts.
In case of connecting more than one axle to a single supply, always connect each drive
DIRECTLY to the supply and keep the wires as short as possible, twist the + and - leads
together as twisted pairs. (try not to exceed 1,5 feet (1m) in length.
