Cable Routing
There are three main categories of cabling for the drive discussed in previous sections.
Motor cables:
connecting motor and drive, these supply power to/from the motors.
Control cables:
returning information from the motors to the drives (e.g. Encoder info or temperature
info) or running information between drives or to other control units on the machine (e.g. Relays to/from
master controllers).
Power supply cables:
connecting power supply unit and drive, this supplies power to/from the drives.
Care should be taken to avoid electromagnetic interference and coupling between cables. It is best practice that
all three categories of cabling be routed separately. Power and motor cables should be separated (as much as
practical) by at least 300 mm, whereas motor and control cables should maintain at least 500 mm separation
over the majority of their length. If control and power cables must cross, they should cross perpendicular (at 90
degrees) to one another.
It is recommended that 24 V and 240 V cables be routed in separate ducts. Where this is not possible, the 24 V
cable should be appropriately insulated for 240 V.

EU Machinery Directive Considerations
Customer applications which use the AMD2000 STO drives must install the same electrical accessories (EMC
filter, Line reactor, Circuit Breakers and Motor/Encoder cables) as specified in the compliance test report and the
User Manual and they must be installed according to the product instructions. The customer cannot use arbitrary
filers/reactors/CB’s/Cables without due diligence. If the customer makes a decision to install different components
to those specified, that is acceptable
but
the machine inspector will compare the specifications of the installed
components to the recommended components. To enable this part variance to be successful, the customer
must
prepare a Technical File (TF) for the change. The TF should present a comparison of the performance
specifications and characteristics of the specified components to the customer selected components and explain
why they would not cause a change to compliance. Also, the customer is the responsible party for the compliance
of the machine to the Machinery Directives including the EMC directive.
