3.6 Default jumper settings
By default the I/O board is delivered with the jumpers in the following positions:
a. 1, 8, 11, 15, 16 , 17, 19, 20 = OFF
b. 2, 3 = ON
c. 4, 5, 6, 7, 10, 12, 13, 14, 18 = pos 1-2
d. 9 = pos 2-3
The default SS1 settings select the TMLCAN protocol with the axisID is 255 (all switches are 0). In
order to quickly change to CANopen protocol, set switch 8 and 1 from SS1 = 1. The CANopen axisID
set will be 1 (because of switch 1=1).
SS2 (STO bypass settings) has all switches set to OFF.
3.7 Axis ID and CAN Protocol selection for CAN drives
The AxisID can be selected by using the sliding switches 1 to 7 on SS1.
Example:
Switch7
ID 6
Switch6
ID 5
Switch5
ID 4
Switch4
ID 3
Switch3
ID 2
Switch2
ID 1
Switch1
ID 0

The CAN protocol selection is done via switch 8 of SS1:
•
CANopen mode, if the switch is ON
•
TMLCAN mode, if the switch is OFF
Remark:
In CANopen mode, if the AxisID is set to 255, the drive remains “non-configured” waiting for a
CANopen master to configure it using CiA-305 protocol. A “non-configured” drive answers only to CiA-305
commands. All other CANopen commands are ignored and transmission of allother messages (including
boot-up) is disabled.
The green Ready LED will blink at 1s intervals until the axisID is different than 255.
3.8 Axis ID Selection for iPOS4808 MY-CAT-STO drives with EtherCAT
The iPOS4808 MY-CAT-STO drives support all EtherCAT standard addressing modes. In case of device
addressing mode based on node address, the iPOS4808 MY-CAT drive sets at bootup the
configured
station alias
address with its AxisID value. The drive AxisID value is set after power on in one of the following
ways:
a) By hardware, function SS1 poition. The AxisID value is computed in the same way as in the case
of the CAN drives.
Remark:
switch 8 on SS1 has no function if the drive is EtherCAT compatible
.
b) By software, setting via EasySetUp a specific AxisID value in the range 1-255.
Remark:
some EtherCAT masters do not work with drives having the
configured station alias
set as 255.
