Motor Connections
DX motors are available in two different styles for most models. The first style has been
designed to meet IP65 waterproofing standards. Cable entries are made through NPT conduit
holes.
The second style comes equipped with one or two MS style connectors. See the table below
for motor connector options. Motors equipped with MS style connectors meet IP65
waterproofing standards. However, the mating cables and connectors meet only IP20
standards. If waterproofing is required, motors with NPT conduit holes should be ordered.
Connections to Waterproof Motors
When connecting an FX amplifier to a waterproof DX motor, there are two connections
required. The first is the resolver and motor temperature signal cable (RC cable). The second
connection involves wiring the three motor phase leads and a motor case ground connection
from the motor to the amplifier.
Resolver Connections
Applications that require cables over 100 feet should be discussed with EMERSON Motion
Control Applications Engineering department.
The RC cable comes in three standard lengths, 15, 25 and 50 feet. This cable assembly has a
9-pin D-subminiature connector on one end (amplifier end) and is not terminated on the other
end (motor end). This allows you to cut the cable to length if non-standard lengths are
required. The 9-pin D-subminiature connector mates with the resolver 9-pin D-subminiature
connector on the bottom plate of the amplifier. This connector must be screwed down to
ensure reliable operation.
Resolver connections at the motor end are made to a terminal strip inside the rear of the motor.
You must remove the back cover of the motor for access to the resolver and stator terminal
strips. A slot on the motor body is provided for pressure to remove the cover.
