Overview 1-11
Axis Modules
Axis modules, with continuous output currents (RMS) of 3.0, 4.5, 7.5
23.3 and 35.0A, convert the DC power supplied by the system module
to a variable AC voltage. You will require one axis module for every
1326A
x -B xxxx servo motor you plan to run using the 1394. Choose
each axis module based on the current requirements of the servo motor.

External Shunt Module (used with 22 kW System)
Shunt modules with (rms) power output of 300, 900, 1800 and
3600W continuous, 160,000W peak are available for use with the
smart power 22 kW system module. The shunt module dissipates
excess regenerative power from the Bulletin 1394 system. You must
use one shunt module with each 22 kW smart power system module.
Available in two sizes, each package contains an integral fuse and
terminal block. The 3600W package is available with a 115/230V AC
cooling fan. Choose your shunt module based on the shunt
requirements of the 1326A
x -B xxxx servo motors you plan to run
using the 1394.
Note: 5 and 10 kW system modules can use an optional 1400W shunt
module kit to dissipate excess regenerative energy
(unpackaged components).
