The 9/Series CNC supports Allen-Bradley Series 1386, 1387, 1388, 1389,
1391, and 1392 analog servo drive systems. If you are using a 1387 drive,
it must be equipped with 115V ac and the dynamic-braking option. Refer
to appendix D for details on wiring one of these AB drives to your control.
Table 3A.H lists references to help you select a suitable drive system.

High Performance AC Drive (460V and 230V) Product Data
The processor module provides a + 10V analog velocity command output
for up to four drive amplifiers. This analog voltage is generated from a
12-bit value plus an additional sign bit (13 bits total) and interfaces to drive
amplifiers with a 2K-20K ohm range.
Servo Motors are used to drive the axes of the machine because of their
ability to respond accurately to small positioning commands. Typically
they have two feedback devices mounted on them, one that provides
position data to the processor module, and one that provides velocity data
to the servo amplifier.
Any servo motor that meets the needs of your machine tool and is
compatible with the servo amplifier that you will be using, can be used
with the control.
Allen-Bradley has a wide selection of servo motors that can be used with
the Allen-Bradley servo amplifiers. These motors can also be used with
other servo amplifiers that are compatible with the servo interface. For
more information on Allen-Bradley servomotors, contact your
Allen-Bradley sales representative.
Motor installation and maintenance will depend on the type of motor used
and the hardware to which it is mounted. For more specific information,
refer to the documentation prepared by your drive and motor
manufacturers.
