XC77 • XAC77 - Encoder ATEX
5.7 XAC77 with DeviceNet interface (XAC77xx/xxxxxFD-...)
ATEX encoders with DeviceNet interface are based on the Hx58 FB series encoders, changes are
described below; refer to the transmission specifications described in the Hx58 FB DeviceNet
manual; differences, if any, are described below. Furthermore they need the
Lika_HS58x_FDV_Vx.eds
(singleturn) or
Lika_HM58x_FDV_Vx.eds
(multiturn) EDS file. User's
manual and EDS file are available at the address:

WARNING

Do not open the device for any setting!

The diagnostic LEDs are not available for this model.

Provided cable is not a CANopen certified cable, anyway it is fitted with bus input and output
to avoid installing stubs on the CANopen network.

To avoid irreparable damages to the encoder wires which are not used must be cut at different
lengths and insulated singularly.

The node address (00hex … 3Fhex) is pre-set at Lika premises according to the order code
shown in the table
a
below; value is expressed in hex.

The baud rate is pre-set at Lika according to the order code shown in the table
a
below.

The bus termination resistor (necessary if the encoder is either the first or the last in the
transmission line, i.e. at the ends of the network) is pre-set at Lika premises according to the
order code shown in the table
a
below.

As an alternative the termination resistor can be provided outside the device (120

resistor
between CAN High and CAN Low outputs) as shown in the following scheme

aabt
aa: node address (hex) 00hex … 3Fhex (00 … 63)
b: baud rate D = 125 kbit/s
E = 250 kbit/s
F = 500 kbit/s
t: termination resistor 0 = deactivated
1 = activated
EXAMPLE
:
XAC77
xx/xxxxx
FD
-xx-xxx/
0DD0
0D= node address 0Dhex (13dec);
D = baud rate 125 kbit/s
0 = termination resistor deactivated
Address, baud rate and resistor are
set by means of internal dip
switches and cannot be modified.
