TJ2-ECT__
3.11.1 Introduction
EtherCAT is an open high-speed industrial network system that conforms to
Ethernet (IEEE 802.3). Each node achieves a short cycle time by
transmitting Ethernet frames at high speed.
A mechanism that allows sharing clock information enables high-precision
synchronization control with low communications jitter.
The TJ2-ECT__ controls EtherCAT devices in a cyclic and deterministic way.
EtherCAT devices can be:
•
Servo Drives.
•
Inverters.
•
I/Os.
Note
Only specific EtherCAT devices are supported. This depends on
the firmware version of the connected TJ2-MC__.
Only master to slave communication is supported. Master to mas-
ter communication is not supported.
The TJ2-ECT__ has these visible parts:

Together the TJ2-ECT__ and its devices form a serial network. The first unit
in the network is the TJ2-ECT__.
•
One TJ2-ECT04 can control up to 4 Servo axes.
•
One TJ2-ECT16 can control up to 16 Servo axes.
•
One TJ2-ECT64 can control up to 64 Servo axes.
