Section 5B
9/440HR CNC/Drive System
5B-4
This chapter only covers the 9/440HR CNC assembly and the
interconnecting wiring board. The 9/440HR CNC assembly consists of a
CNC processor board and a high–resolution CNC feedback board both
connected into a mounting bracket. Refer to the section entitled
Connecting Feedback for details on the high–resolution CNC feedback
board and refer to the section entitled 9/440HR CNC Wiring Board for
details on the interconnecting wiring board. For details on the drive/power
portion of the 9/440HR system module, refer to your 1394 Digital AC
Multi-Axis Motion Control System Users Manual (publication 1394-5.0)
and the section entitled Power Terminal Block Connection.
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 HIPERFACE
 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.
