AxisLink Specifications
IMC-S/23x-L and IMC-S/23x-RL models only.
Baud Rate
Standard and extended 
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).
