5 EtherCAT Communication
5.1 Overview
The EtherCAT communication card (hereinafter referred to as the ECAT card) supports
the super‑high‑speed I/O network for industrial field application. The protocol can be
used to directly process data at the I/O layer. It features high efficiency, flexible
topology, and ease‑to‑use.
When this card is installed on the AC drive, the AC drive networking function is
implemented and the AC drive can serve as a slave station of the field bus and be
controlled by the field bus master station, improving the communication efficiency.
The EtherCAT communication card supports a minimum sync period of 500 μs.
In this guide, the ECAT card software version must be 1.08 or later. After the ECAT
card is installed and the AC drive is powered on, query the parameter Fd‑91 of the
power supply unit. The device description XML file is MD800_9Axis_Vn.nn.xml,
wherein n.nn indicates the version which must be 0.16 or later.
5.2 Installing
The ECAT card is a built‑in extension card of the AC drive. Power off the AC drive, wait
for about 10 minutes until the charging indicator of the AC drive is completely turned
off, and then install the ECAT card.
Check whether the ECAT card is firmly inserted to the AC drive and prevent the signal
socket between boards from being damaged by the pulling force of external signal
cable.
