Installation and Hookup 4-33
Publication 999-122 - January 1997
Plug the terminal block into the channel (A or B) on the RIO adapter
which you wish to use for RIO communications. Either channel can be
used–the selection is made in the Application Setup Menu. See the
Setup section of this manual for information on configuring RIO
operation.
Connecting AxisLink
(Optional)
IMC-S/23x-L and IMC-23x-RL models include AxisLink, which
allows linking multiple IMC S Class controllers and ALECs (AxisLink
Encoder Converter modules) together so that axes on one controller or
ALEC can be used as master axes for electronic gearing and cams on
other controllers. On these models, the AxisLink cable is connected to
channel A of the AxisLink option using a 3-terminal pluggable terminal
block on the AxisLink option front panel. The AxisLink option front
panel is shown below.
Important: All nodes on the same AxisLink network should be
operated at the same servo update rate.
ALECs cannot currently operate in extended length mode.
!
ATTENTION: Even though the front panel of the
AxisLink option is identical to the RIO Adapter front
panel, the two options are not interchangeable. Do not
mix RIO and AxisLink connections or neither system
will work properly.
