Figure 40: ECF Cable Wiring Diagram, FX-316 through FX-4120
A general rule for the minimum cable bend radius is ten times the cable outer diameter.
This cable has a 9 pin D connector on one end (amplifier end) and an MS style connector on
the other end (motor end). The 9 pin D connector mates with the “resolver” 9 pin D connector
on the bottom plate of the amplifier. This connector must be screwed down to ensure reliable
operation. The ECF cable wiring diagram is shown above.
Stator Connections
Cable connections from the amplifiers to the motors are basically the same except for the
physical location of the MS connectors on the motors. The DX-208C has only one MS
connector. The DX-316C and DX-340C motors have two MS connectors mounted one in
front of the other. The DX-455C, DX-490C and DX-4120C MS connectors are mounted side
by side.
Connection to a motor with MS style connectors is made with an ECS, ECM or ECL cable
depending on the drive model. These cables are equipped with an MS style connector on one
end (motor end) and wire leads on the other end (amplifier end). The ECS cable, used on the
DX-208C motors, contains the resolver signal wires in a 9 pin connector, the unterminated
stator wires and wires for an optional motor with brake.
