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).
