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 fieldbus 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.
2.
3.
4.
5.
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.
The [OFF] key on the LCP of the frequency converter does not disconnect the equipment from mains and is thus not to be used as a safety switch.
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.
The earth leakage currents are higher than 3.5 mA.
Protection against motor overload is not included in the factory setting. If this function is desired, set par. to data value ETR trip or data value
ETR warning.
6.
7.
NB!
The function is initialised at 1.16 x rated motor current and rated motor frequency. For the North American market; the ETR functions provide class 20 motor overload protection in accordance with NEC.
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.
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
1.
2.
3.
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.
While parameters are being changed, the motor may start. Consequently, the [OFF] key must always be activated.
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 MCA 122 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.
130BA903.10
Illustration 3.2: Star topology

130BA904.10
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 3 How to Install
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.

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 environments 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.
Max. 32 drives

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 FC 200/FC 300 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.

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. 12-12 is set to OFF, link speed and duplex mode can be configured manually in par. 12-13 and 12-14.
Par. 12-13,
Link Speed

Modbus TCP 4 How to Configure
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 FC100/200/300 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 FC 302 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”

Modbus TCP 4 How to Configure
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:
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.
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 FC102/FC202/FC 300’s are running in a ring/redundant line topology.

5.2 Modbus TCP Message Framing Structure
5.2.1 Function Code
The function code of a message frame contains 8 bits. Valid codes are in the range of 1-FF. Function codes are used to send messages between master and slave. When a message is sent from a master to a slave device, the function code tells the slave what kind of action to perform. When the slave responds to the master, it uses the function code to indicate either a normal (error-free) response, or that some kind of error occurred (called an exception response). For a normal response, the slave simply echoes the original function code. For an exception response, the slave returns a code that is equivalent to the original function code with its most significant bit set to logic 1. In addition, the slave places a unique code into the data field of the response message. This tells the master what kind of error occurred, or the reason for the exception. Please also refer to the section
Function Codes Supported by Modbus TCP and Exception Codes
.
5.2.2 Data Field
The data field is constructed using sets of two hexadecimal digits, in the range of 00 to FF hexadecimal. These are made up of one TCP character. The data field of messages sent from a master to slave device contains additional information which the slave must use to take the action defined by the function code.

The actual reference [Ref. %] in the VLT frequency converter depends on the settings in the following parameters:
Par. 1-23
Motor Frequency
Par. 1-25
Motor Nominal Speed
Par. 3-02
Minimum Reference
Par. 3-03
Maximum Reference
All references provided to the frequency converter are added to the total reference value. If a reference is to be controlled by the fieldbus only, ensure that all other reference inputs are zero.
This means that digital and analogue input terminals should not be used for reference signals. The default setting (0%) should be maintained for preset references in par. 3-10
Preset Reference
.
NB!
If the bus speed reference is negative, and the control word contains a run reverse signal, the drive will run clockwise (- - is +).
MAV is scaled in the same way as the reference.

7.1.2 Alarm Word and Warning Word
Alarm word and warning word are shown in the display in Hex format. If there is more than one warning or alarm, a sum of all warnings or alarms will be shown. Warning word and alarm word are displayed in par. 16-90 to 16-95. For more information on the individual alarms and warnings, please refer to: FC 200/FC 300 Design Guide.
NB!
Please note that the availability of the individual alarms and warnings are dependent on the drive type: /FC102/202/FC 300 series.

Warning and Alarm Messages
There is a clear distinction between alarms and warnings. In the event of an alarm, the frequency converter will enter a fault condition. After the cause for the alarm has been cleared, the master must acknowledge the alarm message in order to start operation of the frequency converter again. A warning, on the other hand, may appear when a warning condition arises, then disappear when conditions return to normal without interfering with the process.
Warnings
All warnings within the frequency converter are represented by a single bit within a warning word. A warning word is always an action parameter. Bit status FALSE [0] means no warning, while bit status TRUE [1] means warning. Each bit status has a corresponding text string message. In addition to the warning word message the master will also be notified via a change in the status word.
Alarms
Following an alarm message the frequency converter will enter a fault condition. Only after the fault has been rectified and the master has acknowledged the alarm message by a bit in the Control Word, can the VLT resume operation. All alarms within the VLT are represented by a single bit within an alarm word. An alarm word is always an action parameter. Bit status FALSE [0] means no alarm, while bit status TRUE [1] means alarm. In CIP, Alarms are divided in to two categories:
