Axis Module - Connect up to four axis modules to the 9/440HR
CNC/Drive system (depending on your system module selection). Axis
modules convert the DC power supplied by the system module to a
variable AC voltage (460V AC input provides 460 AC out, derated
380V AC input provides 380V AC out). This voltage will have
controlled phase, amplitude, and frequency for regulating the speed,
torque, and direction of the 1326AB AC Servomotors. The axis
modules are available in a wide range of power ratings with continuous
peak capabilities of 200% of continuous rating for short durations.
Make motor connections for power, ground, brake, and thermal sensor
to each axis module. Each 1326AB servomotor is wired to its own axis
module.
1326AB motors are described in the 1326AB Servomotor Product Data
(publication 1326A-2.9). The 1326AB series of motors operate at either
460V AC or 380V AC. Connection of these motors is made directly to
the Axis Module.
Each 1326AB motor can be equipped with incremental or absolute
high--resolution feedback devices that use the HIPERFACEÒ electrical
interface. An external A quad B feedback device can also be used for
positioning feedback. These high--resolution feedback devices are
connected to the feedback board found in the system module.
