Connecting Axis-Specific
Discrete I/O

The IMC-S/23x provides home and overtravel limit switch inputs and
a drive fault input for each axis. These axis-specific discrete inputs are
optically isolated and filtered to eliminate switch bounce. In addition,
the IMC-S/23x provides a normally open relay contact drive enable
output for each axis.

Connect axis-specific I/O to the IMC-S/23x using a separate
4100-CCAxxF pre-engineered cable assembly for each axis as shown
below.

The I/O power supply connected to the IMC-S/23x (see Connect the
I/O Power Supply later in this section) provides 24V DC at up to 3
Amperes total maximum for powering the axis-specific discrete I/O.
This power is available on the Red and Black conductors in the
4100-CCAxxF cable assembly as shown above. Note that a user-
supplied terminal block (TB) is generally required to connect the I/O
devices to the 4100-CCAxxF cable assembly.
