1.GENERAL

Vacon NX frequency converters can be connected to the LonWorks® network using a fieldbus board. The converter can then be controlled, monitored and programmed from the Host system.

The LonWorks® board shall be installed in slot E on the control board of the frequency converter.

LONWORKS technology has been developed by Echelon Corporation. LONWORKS network is used in applications like industry and building automation, controlling household electronics, medical instrumentation and many others. The target of the LONWORKS network is to provide a common vendor independent communication network for intelligent devices.

In a LONWORKS network, no central control or master-slave architecture is needed. Nodes on a network communicate with each other using LonTalk® protocol. Interoperable nodes use Standard Network Variable Types (SNVT) for communicating over the network. The definition of an SNVT includes units, a range, and an increment. Vacon option board uses only Standard Network Variable Types for the data types.

All network variables are either input (data is coming from the network to the device) or output (data is sent to the network by the device) network variables. When network variables on different nodes on the network have been bound together by an installation tool, passing of data is automatic between the right nodes. Only the same type of network variables can be bound together, so it is very important to have compatible interfaces.

Internal components and circuit boards are at high potential when the frequency converter is connected to the power source. This voltage is extremely dangerous and may cause death or severe injury if you come into contact with it.

TECHNICAL DATA	VACON • 5

2.2Physical media and wiring

LONWORKS networks can be implemented on many different physical media. Vacon OPTC4 option board is equipped with an FT-X1 transceiver supporting the Free Topology transformer coupled network, which allows the network wire to be connected as bus, star, loop or combination of these. This media reaches a communication speed of 78kBits/s. The FT-X1 transceiver is compatible with Echelon’s LPT-10 Link Power Transceiver, and these transceivers can communicate with each other on a single twisted pair cable.

Figure 2-4. Loop Topology

Up to 64 FTT-10 transceiver nodes are allowed per network segment, the individual segments can be connected together by a router. See Table 3-1 for recommended cable types and cable lengths for FTT-10. Even if unshielded cable types are recommended to be used with this type of transceiver, it is still highly recommended to use only shielded cables with frequency

2.3Profiles

LonMark Functional Profiles describe in detail the application layer interface, including the network variables, configuration properties, and default and power-up behaviors required on LonMark devices for specific, commonly used control functions.

2.3.1Variable Speed Drive Profile

Leading manufacturers of drive technology have jointly defined the LonMark profile. The profile specifies how the drives are to be parameterized and how the setpoints and actual values are to be transmitted. This enables drives from different vendors to be exchanged. The profile contains necessary specifications for speed control and positioning. It specifies the basic drive functions while leaving sufficient freedom for application-specific expansions and further developments.

3.LONWORKS FIELDBUS BOARD LAYOUT AND CONNECTIONS

Vacon LonWorks Fieldbus Board is connected to the fieldbus through 3-pin pluggable bus connector. The communication with the control board takes place through the standard Vacon Interface Board Connector.

3.2Grounding of bus cable shield in OPT-C4

The bus cable shield can be grounded to the frame of the frequency converter through an RC filter located on the OPT-C4 board.

Note: Normally, the option board has already been installed in slot E of the control board. It is not necessary to detach the whole board for the grounding of the bus cable shield. Just detach the terminal block.

3.2.1 Grounding the bus cable shield directly to the frequency converter frame using the RCfilter

1Strip about 5 cm of the cable as shown in the picture.

Figure 3-2.

2Leave no more than 7 mm of the data cable outside the terminal block (Figure 3-3) and strip the data cables at about 5 mm to fit in the terminals (Figure 3-4).

3Insert the data cables and the shield in their respective terminals. See Table 3-1.

4If the LonWorks board was detached from the control unit place it into slot E of the control board (see board installation on page 12). Otherwise attach the terminal block. Fix the cable on the frame with the clamp.

3.3Bus termination resistors

To assure a proper data transmission, termination of the network segments is required. Depending on the type of network, either one or two terminations are necessary. Free topology network segment requires only one termination whereas a doubly terminated bus topology requires two.

The jumper X5 on the Vacon LonWorks board must be set accordingly. Use 94-ohm termination resistance when only one termination is needed and 47-ohm for two terminations.
