iPOS4808 VX Technical Reference
Operation Mode and Axis ID Selection
3.4.5.1
Selection Levels on Axis ID Inputs
On iPOS4808 the selection of the operation mode: CANopen or TMLCAN as also of the axis ID
number is done by setting different voltage levels on the inputs AxisID 0 (pin B5), AxisID 1(pin B6)
and AxisID 2 (pin B7). Each input can be set to one of the following 7 levels:
Level
Connection needed
L0
Connect input directly to ground (for example pin B3)
L1
Connect input through a 4.7
kΩ resistor to ground
L2
Connected input through a 22
kΩ resistor to ground
L3
Nothing connected – leave input open
L4
Connect input through a 22
kΩ resistor to +5Vdc (for
example pin B10)
L5
Connect input through a 4.7Kohm resistor to +5Vdc
L6
Connect input directly to +5V
The operation mode selection is done via AxisID 2:
•
CANopen mode, if the input levels are: L0, L1 or L2
•
TMLCAN mode, if the input levels are L3, L4, L5, L6

AxisID 2 input level is set for
CANopen
shows how to set all possible values
for axis ID in this mode of operation.
Remarks:
1. AxisID value is computed with formula: 49 x A 7 x A AxisID0, where each
AxisID can have one of the integer values: 0 to 6 (0 for L0, 1 for L1, 2 for L2, etc.)
2. If the resulting AxisID value is 0 (all 3 inputs are connected to GND), the axis ID will be set
to 127. If the resulting AxisID is greater than 127, the axis ID will be set to 255.

Table 3.2. Axis ID setting in TMLCAN
shows how to set all possible values for axis ID in this mode of operation.
Remarks:
1. AxisID is computed with formula: 49 x (AxisID2 - 3) + 7 x A AxisID0, where each
AxisID can have one of the integer values: 0 to 6 (0 for L0, 1 for L1, 2 for L2, etc.)

If the resulting AxisID value is 0, the axis ID will be set to 255
