1-10 Overview
Axis modules are connected to system modules using slide-and-lock,
module-to-module connections. For information on motors and cables,
refer to the 1326AB 460V, Torque Plus Series, AC Servo Motors Product
Data (publication 1326A-2.9), 1326AS Series 460V, Low Inertia,
Brushless Servo Motors Product Data (publication 1326A-2.10), and
1326 Cables for 460V AC Servo Motors Product Data (publication
1326A-2.11).
In addition to the equipment shown above, you will need to supply the
following:
• Three phase input contactor
• Three phase input fusing
• 24V AC or DC logic power for system module and contactor
enable (Analog Servo only)/DRIVEOK power (all modules)
Refer to Appendix A for information on these topics.
Note: An external shunt resistor kit (1394-SR10A) is available for 5
and 10 kW systems with regenerative loads that exceed the
capacity of the internal 200W shunt resistor provided. Most 5
and 10 kW systems will not require a shunt resistor kit. All 22
kW 1394 based products require an external shunt module
(1394-SR9Ax or 1394-SR36Ax). This includes both 1394 and
8520 catalog items.
System Modules
System modules, available with ratings of 5, 10 and 22 kW (at 460V),
house the system control PCB and convert 360 to 480VAC, three-
phase, 50/60 Hz input power to a 530 - 680V DC link voltage. The 5
and 10 kW system modules have an internal shunt resistor with a
200W continuous rating and a peak rating of 40,000W. The 22 kW
system module requires an external shunt module.
