Installation
6. Care must be taken to align the cover upon installation to prevent damage to the “O” ring
which will destroy the waterproof integrity.
Figure 39: Cable Preparation (Motor End) Example
Connections to Motors with MS Style Connectors
Motors with MS style connectors should be mounted with the connectors pointing downward.
This provides added protection against dust and water ingress.
Two connections are required when connecting the amplifier to a motor equipped with MS
style connectors. An ECF-XXX cable connects the resolver and motor thermostat signals
(this cable is used for all motors that have MS style connectors except the DX-208). The ECS-
XXX, ECM- XXX or ECL-XXX cables connect the three motor phase leads, motor case
ground and motor brake (if required). All connectorized cables required for an FX drive can
be obtained from EMERSON Motion Control. The table below lists the correct cables to be
used with each drive model.
Resolver Connections
Applications that require ECF cables longer than 100 feet should be discussed with
EMERSON Motion Control’s Applications Engineering department.
The ECF-XXX feedback cable comes in three standard lengths (15, 25 and 50 feet) and can
be ordered by the following numbers:
Drive Model Resolver Cable Motor Cable
FX-208/DX-208C Not Required
ECS (contains both motor and resolver
wiring)
FX-316/DX-316C ECF-XXX ECM
FX-340/DX-340C ECF-XXX ECM
FX-455/DX-455C ECF-XXX ECM
FX-490/DX-490C ECF-XXX ECL
ECF-015 = 15 feet ECF-025 = 25 feet ECF-050 = 50 feet
