9. CONNECTION TO SERVO OR SPINDLE

The FANUC servo unit β series with I/O Link (called the b amplifier with
I/O Link in this chapter) is a servo unit that can be easily connected to a
Power Mate via the FANUC I/O Link.
NOTE
Using the b amplifier requires that the Power Mate CNC
manager software function be installed in the Power Mate.
This function is included as one of the option functions.
The β amplifier with I/O Link is connected to the Power Mate using the
usual FANUC I/O Link connection. See Sec. 6.2.
The maximum number of b amplifiers with I/O Link that can be
connected to a control unit depends on the maximum number of FANUC
I/O Link points provided by that control unit, as well as their assignments.
For the Power Mate, the maximum number of FANUC I/O Link DI and
DO points are 1024 and 1024, respectively. One β amplifier with I/O Link
occupies 128 DI/DO points in the FANUC I/O Link. If no units other than
the β amplifiers with I/O Link are connected to the control unit, up to eight
β amplifiers can be connected.
If the b amplifier with I/O Link is used as an I/O Link slave, I/O addresses
are assigned in the PMC in the Power Mate. Because data output from
the slave is made in 16–byte units, the number of input/output points must
be set to 128.
The module names are PM16I (input) and PM16O (output).
The BASE is always 0, and the SLOT is 1.
