1.2 Introduction
MD500 series Ethernet/IP communication card (hereinafter referred to as MD500-EN1
card) is an adapter card for Ethernet/IP 󶍾eldbus. It complies with international Ethernet/
IP bus standards and features high e󶎀ciency, 󶍿exible topology, and easy operation.
It is installed in the MD series AC drive to increase the communication e󶎀ciency and
implement the AC drive networking function, which enables the AC drive to be a slave
controlled by the 󶍾eld bus master.
The MD500-EN1 card software version required is 1.00 or later (check the software
version in U0-67 upon power-on after installing the card). The corresponding EDS 󶍾le
name is MD500P_EIP_V1.00.eds. This user guide is applicable only for the MD500-PLUS
series AC drive. If you need to use the MD500-EN1 card with other AC drives, contact our
technical support for details.

2.1 Installation
The MD500-EN1 is installed inside the MD500 series AC drive. Before installation, de-
energize the AC drive and wait about 10 minutes until the charging indicator on the AC
drive becomes o󶍽. Then, insert the MD500-EN1 card into the AC drive and fasten the
screws to avoid damage caused by external signal cable tension on the signal socket
between boards. The installation is shown in"Figure 2-1 Installation of the MD500-EN1
card".
Note that the ground terminals of both the MD500-EN1 card and AC drive must be
connected properly, as shown in"Figure 2-2 Ground terminal connection between the
MD500-EN1 card and the AC drive".

2.2.2 EMC Wiring
■During on-site installation and commissioning, the signal cables and power cables
must be laid in di󶍽erent ducts. Never bundle the signal cables and power cables
together to prevent communication interference.
■Motor enclosure must be connected to PE of the AC drive. Meanwhile, the
grounding cable on the motor housing side must be connected properly. Failure to
comply will result in poor grounding e󶍽ect.
■Shielded cables are recommended. Connect the shield to PE of the AC drive.

3 Ethernet/IP Communication Protocol
3.1 Description of I/O Messages Data
24 I/O Messages are available in the MD500-EN1 expansion card for data transmission,
in which 12 I/O messages transmit data from master station to slave station and another
12 I/O messages transmit data from slave station to master station.
The I/O Messages are used by the master station to modify and read AC drive data in real
time and perform periodic data exchange. Data communication addresses are directly
con󶍾gured by the AC drive. The speci󶍾c functions are as follows:
◆ Real-time setting of AC drive control command and target frequency
◆ Real-time reading of AC drive current state and operating frequency
◆ Function parameter and monitoring data real-time exchange between the AC drive
and Ethernet/IP master station
The I/O Messages data is used for periodic data exchange between the master station
and AC drive, as described in the following table.

View MAC address when DHCP/BOOTP function is used. To view the MAC address,
read the label attached to the expansion card or check the related parameter (see "4.3
Parameters of AC Drive Communication Card" for details).
This card supports IP address con󶍿ict detection. When other devices in the network
share the same IP address with the expansion card, D7 indicator will be steady ON and
bit2 of FD-58 will be changed to 1.
The following three cases are present in IP address con󶍿ict detection.

4 Parameters Related to Communication
- 19 -
No. Case Symptom Solution
1
Both devices support IP
address con󶍿ict detection. The
two devices are powered on
one after another.
The device powered on 󶍾rst
uses the IP address and
continues to operate. The
device powered on later
enters the con󶍿ict mode.
Check device IP address
and then modify the
repeated one.
2
Both devices support IP
address con󶍿ict detection.
The two devices are powered
on at approximately the same
time.
The two devices enter the
IP address con󶍿ict mode
simultaneously.
3
One device supports IP address
con󶍿ict detection and the
second device does not.
Regardless of which device is
powered on 󶍾rst, the device
that does not support IP
address detection uses the
IP address. The device that
supports IP address con󶍿ict
detection enters the con󶍿ict
mode.
NOTE
◆When the DHCP server assigns an IP address to the expansion card,
active con󶍿ict detection applies. Later, passive detection applies. If
the devices are separately assigned with the same dynamic (static) IP
address on the same network, both expansion cards do not report IP
address con󶍿ict.
◆When using the DHCP function to assign IP addresses, the address
assignment would fail if IP address con󶍿ict occurs.
