1.1.2 Safety Note
The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor, frequency converter
or network may cause damage to the equipment, serious personal injury or death. Consequently, the instructions in this manual, as well as
national and local rules and safety regulations, must be complied with.
1.1.3 Safety Regulations
1. The frequency converter must be disconnected from mains if repair work is to be carried out. Check that the mains supply has been disconnected and
that the necessary time has passed before removing motor and mains plugs.
2. The [OFF] key on the Keypad of the frequency converter does not disconnect the equipment from mains and is thus not to be used as a safety switch.
3. Correct protective earthing or grounding of the equipment must be established, the user must be protected against supply voltage, and the motor must
be protected against overload in accordance with applicable national and local regulations.
4. The earth leakage currents are higher than 3.5 mA.
5. Protection against motor overload is not included in the factory setting. If this function is desired, set par. to data value Electronic Thermal Overload
trip or data value Electronic Thermal Overload warning.
NB!
The function is initialised at 1.16 x rated motor current and rated motor frequency. For the North American market; the Electronic Thermal Overload functions
provide class 20 motor overload protection in accordance with NEC.
6. Do not remove the plugs for the motor and mains supply while the frequency converter is connected to mains. Check that the mains supply has been
disconnected and that the necessary time has passed before removing motor and mains plugs.
7. Please note that the frequency converter has more voltage inputs than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) and external
24 V DC have been installed. Check that all voltage inputs have been disconnected and that the necessary time has passed before commencing repair
work.

1.1.4 Warning against Unintended Start
OPCEIP EtherNet/IP
1
1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the frequency converter is connected
to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient.
2. While parameters are being changed, the motor may start. Consequently, the [OFF] key must always be activated.
3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload or a fault in the supply
mains or the motor connection ceases.
Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.
Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load sharing (linkage of DC intermediate circuit), as well as the motor
connection for kinetic back up.
Please take note of discharge times and further safety guidelines from the section: “Safety and conformity”, in the respective Design Guide (MG.33.Ax.yy).

3.1.4 Topology
The OPCEIP features a build-i n Ethernet-switch, thus having two Ethernet RJ-45 connectors. This enables the possibility for connecting several EtherNet/IP options
in a line topology as an alternative to the typical star-topology.
The two ports are equal, in the sense that they are transparent for the option. If only one connector is used, either port can be used.

OPCEIP EtherNet/IP
Illustration 3.2: Star topology
Illustration 3.3: Line topology
NB!
For line topology please refer to section: “Recommended design rules” In a line topology all drives must be powered, either by mains or by their 24 V DC option
cards, for the build-in switch to work.
10
NB!
Please observe that mounting drives of different power-sizes in a line topology may result in unwanted power-off behaviour.
Smaller drives discharge faster than bigger drives. This can result in loss of link in the line topology, which may lead to control word timeout.
To avoid this, mount the drives with the longest discharge time first in the line topology.
OPCEIP EtherNet/IP

Illustration 3.4: Ring/redundant line topology
NB!
For this type of topology it is crucial that the network switch supports Spanning Tree Protocol (STP), and that STP is enabled. For more information on Spanning
Tree please refer to section IP traffic.
3.1.5 Network
It is of high importance that the media chosen for Ethernet data transmission are suitable. Usually CAT 5e and 6 cables are recommended for industrial applications.
Both types of cable are available as Unshielded Twisted Pair and Shielded Twisted Pair. Generally shielded cables are recommended for use in industrial envi-
ronments and with frequency converters.
A maximum cable-length of 100 m is allowed between switches.
Optical fibres can be used for gapping longer distances and providing galvanic isolation.
For connecting EtherNet/IP devices both hubs a nd switches can be used. It is, however, recommended always to use suitable industrial graded Ethernet switches.
For more information regarding IP-switching, please refer to section: IP Traffic in this manual.
11
3.1.6 Recommended Design Rules
While designing Ethernet networks special attention and caution must be taken regarding active network components.
While designing a network for line topology it is important to notice that a small delay is added with each every switch in the line.
It is not recommended to connect more than 32 drives in a line at any API. Exceeding the recommended design rules, may result in failing communication.

3.1.7 EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the Ethernet network. Additional EMC information is available
in the AF-650 GP/AF-600 FP series Design Guide.
NB!
Relevant national and local regulations, for example regarding protective earth connection, must be observed.
The Ethernet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high frequency noise from one cable to the
other. Normally a distance of 200 mm (8 inches) is sufficient, but maintaining the greatest possible distance between the cables is recommended, especially where
cables run in parallel over long distances. When crossing is unavoidable, the Ethernet cable must cross motor and brake resistor cables at an angle of 90 degrees.

*= Class C IP address example. Any valid IP address can be entered.
NB!
A power-cycle is necessary after setting the IP parameters manually.
Setting up drive with automatic (BOOTP/DHCP) assigned IP address:
Par. Name Value
EN-00 IP Address Assignment [1] DHCP/[2] BOOTP
EN-01 IP Address Read only
EN-02 Subnet Mask Read only
EN-03 Default Gateway Read only
By IP address assigned by DHCP/BOOTP server, the assigned IP Address and Subnet Mask can be read out in par. EN-01 and EN-02. In par. EN-04 DHCP Server,
the IP address of the found DHCP or BOOTP server is displayed. For DHCP only: The remaining lease-time can be read-out in par. EN-05 Lease Expires.
Par. EN-09, Physical Address reads out the MAC address of option, which is also printed on the label of the option. If using fixed leases together with DHCP or
BOOTP, the physical MAC address is linked with a fixed IP address.
NB!
If no DHCP or BOOTP reply has been received after 4 attempts (e.g. if the DHCP/BOOTP server has been powered off), the option will fallback to the last good
known IP address.
15
OPCEIP EtherNet/IP
Par. EN-03, Default Gateway is optional and only used in routed networks.
Par. EN-06, Name Servers
Par. EN-07, Domain Name
Par. EN-08, Host Name
Are used with Domain Name Server systems and are all optional. If DHCP or BOOTP is selected as IP address assignment, these parameters are read only.
NB!
It is only possible to assign valid class A, B and C IP address to the option. The valid ranges are shown in the below table:

Class A 1.0.0.1 - 126.255.255.254
Class B 128.1.0.1 - 191.255.255.254
Class C 192.0.1.1 - 223.255.254.254
4.1.2 Ethernet Link Parameters
Parameter group EN-1# holds information Ethernet Link information:
EN-10 Link Status
EN-11 Link Duration
EN-12 Auto Negotiation
EN-13 Link Speed
EN-14 Link Duplex
Please note the Ethernet Link Parameters are unique per port.
Par. EN-10, Link Status and par. EN-11, Link Duration displays information on the link status, per port.
Par. EN-10, Link Status will display Link or No Link according to the status of the present port.
Par. EN-11, Link Duration will display the duration of the link on the present port. If the link is broken the counter will be reset.
Par. EN-12, Auto Negotiation – is a feature that enables two connected Ethernet devices to choose common transmission parameters, such as speed and duplex
mode. In this process, the connected devices first share their capabilities as for these parameters and then choose the fastest transmission mode they both
support.
By default this function is enabled.
Incapability between the connected devices, may lead to decreased communication performance.
To prevent this, Auto Negotiation can be disabled.
If par. EN-12 is set to OFF, link speed and duplex mode can be configured manually in par. EN-13 and EN-14.
Par. EN-12, Link Speed – displays/sets the link speed per port. “None” is displayed if no link is present.
Par. EN-14, Link Duplex – displays/sets the duplex mode per port.
Half-duplex provides communication in both directions, but only in one direction at a time (not simultaneously).
Full-duplex allows communication in both directions, and unlike half-duplex, allows for this to happen simultaneously.

OPCEIP EtherNet/IP
4.1.4 IP traffic
The use of Ethernet based network for industrial automation purposes, calls for careful and thorough network design. Especially the use of active network
components like switches and routers requires detailed know-how about the behaviour of IP traffic.
Some important issues:
Multicast
Multicast traffic; is traffic that is addressed to a number of recipients. Each host processes the received multicast packet to determine if it is the target for the
packet. If not, the IP package is discarded. This causes an excessive network load of each node in the network since they are flooded with multicast packages.
The nature of EtherNet/IP traffic is that all Originator-to-Target traffic is Unicast (point-to-point) but Target-to-Originator traffic is optional Multicast. This enables
that several listen only -connections can be made to a single host.
In switched networks hosts also have the risk of becoming flooded with multicast traffic. A switch usually forwards traffic by MAC address tables build by looking
into the source address field of all the frames it receives.
A multicast MAC address is never used as a source address for a packet. Such addresses do not appear in the MAC address table, and the switch has no method
for learning them, so it will just forward all multicast traffic to all connected hosts.
IGMP
IGMP (Internet Group Management Protocol) is an integrated part of IP. It allows hosts to join or leave a multicast host group. Group membership information is
exchanged between a specific host and the nearest multicast router.
For EtherNet/IP networks it is essential that the switches used, supports IGMP Snooping. IGMP Snooping enables the switch to “listen in" on the IGMP conversation
between hosts and routers. By doing this the switch will recognise which hosts are members of which groups, thus being able to forward multicast traffic only to
the appropriate hosts.
Spanning Tree Protocol (STP)
For an Ethernet network to function properly, only one active path can exist between two nodes. Spanning-Tree Protocol is a link management protocol that
provides path redundancy while preventing undesirable loops in the network.
When loops occur, some switches see stations appear on both sides of it self. This condition confuses the forwarding algorithm and allows for duplicate frames
to be forwarded.
To provide path redundancy, Spanning-Tree Protocol defines a tree that spans all switches in an extended network. Spanning-Tree Protocol forces certain
redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol
costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and re-establishes the link by activating the standby path.
Spanning-Tree Protocol operation is necessary if the AF-650 GPor AF-600 FP’s are running in a ring/redundant line topology.
