6 EtherCAT Communication
6.1 Introduction
Applicable to industrial field ultra‑high speed I/O network, the MD500‑ECAT
communication card (ECAT card for short) operates at the I/O layer and features high
efficiency, flexible topology, and easy operation.
It is installed on the MD520 series AC drive to improve the communication efficiency
and implement AC drive networking, enabling the AC drive to be a slave controlled by
the fieldbus master. It supports a minimum synchronization cycle of 500 μs.
This user guide is applicable to the ECAT card with software of version 1.00 or later
(you can query the version by viewing the parameter U0‑67 of the AC drive after the
card is installed and powered on). The corresponding device profile XML file is
MD500_1Axis_V1.03.xml.
6.2 Installation
The MD500‑ECAT card is embedded in the MD520 series AC drive. Before installation,
cut off the power supply of the AC drive and wait for about 10 minutes until the
charging indicator of the AC drive becomes off. Then, insert the MD500‑ECAT card into
the AC drive and fasten the screws to prevent the signal socket between boards from
being damaged by the pulling force of the external signal cable. "

shows the installation.
After installing the MD500‑ECAT card on the AC drive, connect the ground terminals of
the MD500‑ECAT card and the AC drive properly, as shown in "
