3.3 Encoder connection

3.3.1 Signal cable

The signals connection must be made with balanced shielded cable, appropriate for
differential signal operations.
The signal cables must be installed separately from the other wirings (power, control
cables, etc). Always maintaining a minimum distance of 10 in (25 cm) and if possible,
installing them inside a metallic conduit. The connection on CC9 is made by the XC9
connector (fig. 7).

The connector XC10 is used in connections via terminal. The pins 23 and 24 in this
terminal block can be used to the encoder supply, in case the connector DB9 NOT to be used.

3.3.2 Incremental encoder input signals

The sequence of the input signals and the respective pin position, in the connector XC9,
is described on fig. 8. Also the sequence of signals is described on fig. 9.

3.4 Start-up
At start-up, program Parameter P202 (type of control) = 4 (Vector with encoder) to
operate the inverter with incremental encoder feedback. For more details about Vector
Control consult the operation manual of CFW-09 inverter.
