1.3.4 Network topology
EtherCAT network is generally composed of a master station and multiple slave
stations. The network structure can be divided into the bus type, star type, tree
type, etc., or the combination of several types, realizing flexible device
connection and wiring. The bus-type network topology is shown in the figure
below.

1.3.5 LED indicator description and fault diagnosis
MV810-ECAT01 has two LED indicators: the LED on the PCBA of the expansion box
(LED1 on the left, LED2 on the right, which can be viewed through the fence gap
of the expansion box) and LED on the communication port. The LED on the PCBA
indicates the power status and whether the state machine enters the OP mode;
and the LED on the communication port indicates whether the communication
status of MV810-ECAT01 is normal.

2.2 Installation method
The installation position, interface and steps of MV810-ECAT01 are described
below:
2.2.1 Installation position
MV800 drive series provides two positions for
installation of accessory cards and options: position
1 and position 2 in the right figure (taking enclosure
B as an example, similar for other enclosures),
where position 1 is for the installation of various PG
cards and position 2 is for the installation of PN
options, ECAT options, I/O options and so on.
2.2.2 Installation interface
The electrical interface of the MV810 EtherCAT
option is connected to the drive as shown in the
right figure.

2.2.3 Installation steps
Installation method: front side mounting of ECAT
(1) When the drive is powered off, press the granulated part on the middle-upper
of the lower cover, slide it down firmly to take down the cover, as shown in Fig.
1-1 a.
(2) Use a straight screwdriver to pry open the dustproof cap, as shown in Fig. 1-1
b.
(3) Install the ECAT option: hold the expansion box (a bus card inside) upwards
(indicators up), then align the expansion box with the electrical bus interface
of the installation position 2, and press down horizontally to buckle the spring
snap of the expansion box into the groove at the lower part of the drive, as
shown in Fig. 1-1 c and d.
(4) The bus card is successfully installed, as shown in Fig. 1-1 e.

(5) Grounding: MV810-ECAT01 must be grounded during wiring as shown in Fig.
1-2. You need to prepare and crimp the cable by yourself.
Fig. 1-2 Grounding terminal connection
Grounding method:
connect the B end of the grounding cable to the option’s
grounding terminal block, and you can check the grounding
cable diameter and torque by referring to Table 1-1;
then connect the A end of the grounding cable to the
grounding rack PE (the mark for grounding, circled in Fig. 1-3)
of the drive (taking enclosure B as an example, similar for
others), and you can check the grounding screw
specifications and torque by referring to Table 1-2.

3 EtherCAT Network Reference Model
EtherCAT (CoE) network reference model consists of two parts: the data link layer
and the application layer.
The data link layer is mainly responsible for the EtherCAT communication protocol,
and the application layer of CoE has an object dictionary which includes
communication parameters, application program data and PDO mapping
information.
Process data objects (PDO) consist of objects in the object dictionary that can be
PDO mapped, and the PDO data is defined by PDO mapping. The read/write of
PDO data is cyclic without requirements to look up the object dictionary, while the
read/write of service data objects (SDO) is non-cyclic with requirements to look
up the object dictionary.
Various application layer protocols are available for EtherCAT communication.
The following figure is the EtherCAT structure based on the CANopen application
layer:
