To connect the NextMove e 100 to other EPL devices use CAT5e Ethernet cables - either S/UTP
(unshielded screened/foiled twisted pairs) or preferably S/FTP (fully shielded screened/foiled
twisted pairs). To ensure CE compliance, Ethernet cables longer than 3 m should be S/FTP
cables bonded to the metal backplane at both endes using conductive clamps (see section
B.1.5). Cables may be up to 100 m (328 ft) long. Two varieties of CAT5e cable are available;
‘straight’ or ‘crossed’. Straight cables have the TX pins of the connector at one end of the cable
wired to the TX pins of the RJ45 connector at the other end of the cable. Crossover cables have
the TX pins of the connector at one end of the cable wired to the RX pins of the RJ45 connector
at the other end of the cable.
Provided the network consists of only Baldor EPL controllers and drives (and any hub), straight
or crossed cables may be used. This is because many Ethernet devices, including hubs and all
Baldor EPL products, incorporate Auto-MDIX switching technology which automatically
compensates for the wiring of the straight cable. However, if other manufacturer’s EPL nodes are
included in the EPL network, crossover cables should be used as recommended by the
ETHERNET Powerlink Standardization Group (EPSG).
The NextMove e 100 Ethernet interface is galvanically isolated from the rest of the
NextMove e 100 circuitry by magnetic isolation modules incorporated in each of the Ethernet
connectors. This provides protection up to 1.5 kV. The connector/cable screen is connected
directly to the chassis earth of the NextMove
e 100. For additional noise immunity, especially
where Ethernet cables are frequently unplugged, it is recommended to clamp the outer shields
of Ethernet cables to an earth point. Termination components are incorporated in each of the
Ethernet connectors, so no further termination is required.
The EPL network supports the 100Base-TX (100 Mbit/s) system only, so attempting to connect
slower 10Base-T (10 Mbit/s) nodes will cause a network error.
