2.1.1 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.
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 [STOP/RESET] 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.
3. Correct protective earthing 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 set by par. 1-90
tion
to data value [ETR trip] (default value) or data value [ETR warning]. Note: 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.
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

Warning against Unintended Start
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 stop key [STOP/RESET] must always be activated; following which
data can be modified.
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.
Warning:
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. Refer to the Operating Instructions for further safety guidelines.

3.1.2 Technical Overview
The LonWorks communications structure is similar to that of a local area network (LAN) in that messages are continually exchanged between a number
of processors. A LonWorks system is a local operating network (LON). LON technologyoffers a means for integrating various distributed systems that
perform sensing, monitoring, control, and other automated functions. A LON allows these intelligent devices to communicate with one another through
a variety of communications media using a standard protocol.
LON technology supports distributed, peer-to-peer communications. That is, individual network devices can communicate directly with one another without
the need for a central control system. A LON is designed to move sense and control messages which are typically very short and which contain commands
and status information that trigger actions. LONperformance is viewed in terms of transactions completed per second and response time. Control systems
do not require vast amounts of data, but they do demand that the messages they send and receive are absolutely correct.
Data are transported by means of standard network variable types (SNVTs) which provide a well- defined interface for communication between devices
from different manufacturers. Functional profiles defining the functionality and network variables for a particular family of devices (e.g. frequency con-
verters, pumps etc.) are also available, and supported by the LonWorks option.
3.1.3 Assumptions
These operating instructions assume, that the Danfoss LonWorks option is used in conjunction with a Danfoss FC 100 frequency converter. It is also
assumed that the installed controller supports the interfaces described in this document and that all the requirements stipulated in the controller, as well
as the frequency converter, are strictly observed along with all limitations therein.
3.1.4 Hardware
This manual relates to the
LonWorks option MCA108
, type no. 130B1106 (non-coated) and 130B1206 (coated).

4.1.3 Network Termination
Dependent on the type of topology, at least one of the connected nodes must be terminated (52.5Ω). The option has two built-in termination circuits
which are activated by the terminator switches S300 and S301.
If termination is provided elsewhere in the network, the termination switches should be OFF. If a double-terminated bus topology is used, the first and
the last node should be double-terminated (105Ω).
Termination switch positions are shown in the table below.
Termination type S 300 S 301

4.1.7 EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the LonWorks network. Additional EMC information
is available in the
The LonWorks 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 LonWorks cable must cross motor and brake resistor cables
at an angle of 90 degrees.

Addressing nodes on the LonWorks network is performed at the time of installation using an installation tool or network management tool (e.g. LonMaker).
Addressing requires the retrieval of the Neuron ID for the node.
There are several methods by which the network software can retrieve the Neuron ID and address the node:
1. Service Pin – The push-button service switch sends the Neuron ID over the network.
If the network software prompts the action, press the Service Pin switch (O400) to transmit the Neuron ID over the network. Please refer to
the How to Install section for the location of the Service Pin switch.
2. Query and Wink - Upon receiving a Wink command, both LED’s flashes (½ Hz for 20 sec.) so the installer can locate the node. The option
sends out its Neuron ID over the network in response to the query command.
3. Neuron ID Label – The installer can manually enter the Neuron ID during installation. The Neuron ID can be found on the label of the option
in text and barcode.
Resource Files
A LonMark interface file (.XIF file extension) provides the host processor with device information. Using this file it is possible to design a LonWorks network
without the adjustable frequency converter being physically present. Other resource files are:
• Type file (.typ file extension)
• Format file (.fmt file extension)
• Language description file (.eng, .enu and other file extensions)
