node configurations
1 megabit per second.
Extended length
configuration
500 kilobit per second.
Cable Type
Standard and extended
node configurations
Allen-Bradley 1770-CD RIO cable (Belden 9463 or
equivalent).
Extended length
configuration
Belden 9182, Carol C8014 or equivalent.
Cable Length
Standard and extended
node configurations
25 meters (82 feet) maximum total. Minimum of 1
meter (3 feet) between controllers.
Extended length
configuration
125 meters (410 feet) maximum total. Minimum of 1
meter (3 feet) between controllers.
Number of
Motion Controllers
Standard and extended
length configurations
8 maximum for a total of 32 possible axes.
Extended node
configuration
16 maximum for a total of 64 possible axes.
Addressing
Standard and extended
length configurations
User-selectable address via rotary selector switch on
front panel.
Extended node
configuration
User-selectable address via GML.
Number of Virtual
Master Axes
Standard configuration
4 maximum total; 1 per motion controller maximum.
Any axis on any motion controller can be a virtual
master axis to any other motion controller. Each motion
controller can define a total of two separate axes on any
other motion controllers as virtual master axes, but only
one can be active at any time. A total of four different
axes can be active as virtual master axes at any time.
Extended length and
extended node
configurations
2 maximum total; 1 per motion controller maximum.
Any axis on any motion controller can be a virtual
master axis to any other motion controller. Each motion
controller can define a total of two separate axes on any
other motion controllers as virtual master axes, but only
one can be active at any time. A total of two different
axes can be active as virtual master axes at any time.
Type of Virtual
Master Axes
All configurations
2: Command and Actual. Each virtual master axis may
be defined to report its command or actual position.
Slave Axes
Standard and extended
length configurations
31 maximum total per virtual master axis (3 local + 4
x 7 other motion controllers = 31).
Extended node
configuration
63 maximum total per virtual master axis (3 local + 4
x 15 other motion controllers = 63).
