7.7 Field-bus connection (X5, X6)
The servo drive communicates with the host (and other devices) using one of two Ethernet based field-
buses.
Use quality Cat. 5E or 6, double shielded, standard Ethernet cables
.
Tria-Link
This is a flexible bus developed by Triamec. The drive must be connected
with the other Triamec devices and the Triamec PCI-Adapter card form-
ing a ring topology. Both jacks (X5, X6) are equivalent, they can be used
in any order and are completely interchangeable.
Each Tria-Link RJ-45 connector has two LEDs:
The green LED (Link LED) is normally blinking. This indicates that the
Tria-Link is connected to the next device. If one of the green LEDs is
not blinking, it indicates an open link to the next device. Check de-
vice 24V and the cable/Ethernet connector in this case.
The yellow LED (Lock LED) indicates a successful time synchroniza-
tion of all devices in the Tria-Link, and thus that the link is ready. If
the yellow LED is not illuminated at least ~5sec after drive start up,
the Tria-Link is either:
open, i.e. the ring is not closed or an Ethernet connector is not engaged
one or more devices are not powered
a device has a hardware fault.
EtherCAT
This is a fieldbus disclosed in the IEC standard IEC61158 with real-time capability. It was originally devel-
oped by Beckhoff Automation and is now managed by the EtherCAT Technology Group (ETG).
The drive must be connected to the EtherCAT PCI-Adapter card and the other Triamec devices in a chain
topology starting with the Adapter card. The jacks (X5(Line In), X6(Line Out)) are not equivalent, the
control flow has to be regarded.
In contrast to the Tria-Link, the cyclic data is defined at boot time and cannot be changed later. This
makes debugging through the fieldbus less flexible than with the Tria-Link. However, customers may
still use the USB or Ethernet interface for debugging within Triamec TAM System Explorer.
Exchange of cyclic data between slaves is less flexible than with Tria-Link and is not supported yet
with the current firmware.
Each EtherCAT RJ-45 connector has two LEDs:
The green LED (Line In) is on, to indicate that the drive is connected to the Controller. If the green
LED is Off, it indicates an open connection. Check device 24V and the cable/Ethernet connector in
this case.
The yellow LED (Line Out) is normally Off, except the LED of the last Device in the chain is flashing.
