1.1.2 Safety Note
The voltage of the variable speed drive is dangerous whenever connected to mains. Incorrect installation of the motor, variable speed drive
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 variable speed drive 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-command on the serial bus 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. Do not remove the plugs for the motor and mains supply while the variable speed drive 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.

1.1.4 Warning against Unintended Start
1. The motor can be brought to a stop by means of bus commands while the variable speed drive 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.
3. A motor that has been stopped may start if faults occur in the electronics of the variable speed drive, 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.

3.1.4 Topology
The OPCMBTCP features a build-in Ethernet-switch, thus having two Ethernet RJ-45 connectors. This enables the possibility for connecting several Modbus TCP
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.
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.
Modbus TCP

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.
Illustration 3.4: Ring/redundant line topology
3.1.5 Network
It is of high importance that the media chosen for Ethernetdata 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 Modbus TCP devices both hubs and 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.

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.

4 How to Configure
4.1.1 IP Settings
All IP-related parameters are located in parameter group EN-##:
EN-00 IP Address Assignment
EN-01 IP Address
EN-02 Subnet Mask
EN-03 Default Gateway
EN-04 DHCP Server
EN-05 Lease Expires
EN-06 Name Servers
EN-07 Domain Name
EN-08 Host Name
EN-09 Physical Address
The OPCMBTCP option offers several ways of IP address assignment.
Setting up drive with manual assigned IP address:
Par. Name Value
EN-00 IP Address Assignment [0] MANUAL
EN-01 IP Address 192.168.0.xxx*
EN-02 Subnet Mask 255.255.255.0*
EN-03 Default Gateway optional
*= 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.
Modbus TCP

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.

4.1.3 Configuring the Scanner
For configuring the scanner to communicate to the drive, no system (e.g. EDS, GSD file) file is needed. The AF-600 FP/AF-650 GP is handled as a generic device an
as such, it has to be configured directly in the scanner. The following example setup the scanner to IP addresses 192.168.1.20 and the AF-650 GP to address
192.168.1.20.
Configuring a Modicon scanner.
The following example uses the Unity Pro tool from Group Schneider to configure the PLC. The example only shows the setting up of the Protocol and assigning
I/O mapping to internal memory of the PLC.
Under network, add a network by right clicking the Network menu and select “New Network”
By selecting this menu you will be asked to assign a name to the new network. In this example “AF-600” has been choosen.

IP address 192.168.001.020
Subnetwork mask 255.255.255.0
Gateway address 0.0.0.0
Ethernet Configuration Ethernet Configuration Ethernet II
In the IP Configuration tab, the “Configured” bottom has to be selected, and the IP address and Subnetwork mask has to be filed out. In this example the address
192.168.1.20 is used as the address for the master.
The step assigns the protocol to the scanner, which is done by selecting the scanner and selecting the “Function” menu and enables the Ethernet by selecting “ETH
TCP IP” This brings up the Net Link menu, where “GE” has to be selected. At this time the “GE” Protocol is assign to the Scanner and the last step is to configure the
scanner to read and write holding registers of the AF-650 GP.
