* Encoder 3 (J11) is only available
if the third resolver port (J3) is not
used. J11 is not available on the
single axis 9/440.
** These encoder ports are not
available on the single axis and
three axis 9/440.

Important: If you are using the 1–axis 9/440 resolver–based (cat. no.
8520-1Sx) system, no encoder ports are available. If you are using the
3–axis 9/440 resolver–based (cat. no. 8520-3Sx) system, only one encoder
port (J11) is available. Note, if you use J11, you can not use your third
resolver port.
