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.
1.2.1. 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 control panel 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.
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 not included in the factory setting. If this function is desired, set par. 1-90 Motor
Thermal Protection to
data value
ETR trip 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
commencing repair work.
1.2.2. 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.
1.2.3. 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.

2.2.1. Technical Overview
The Interbus system is divided into two different systems: remote and local.
The remote system enables the user to connect up to 256 stations on a single system with a maximum of 400m cable length between stations.
The local bus system enables the user to establish communication to Input/Output devices through a single twisted pair of Cables. This type of commu-
nication typical uses simple devices, e.g. Digital I/O devices.
The Interbus option described in this manual supports remote bus only. For communication on the remote bus, the Interbus system provides two different
types of communication: Process Data and PCP (Peripherals Communication Protocol). The Process Data is cyclic communication to devices with high
priority.
Examples of this type of communication are digital and analogue I/O or control word and reference to frequency converters.
PCP communication is used for communications which do not require high speed and typically only are activated on request from the user-written program.
Typical time to read/write a single value is 100 to 200 milliseconds. Examples of this type of communication are configuration data, or reading of service
parameters such as running hours, numbers of power ups and kWh.
2.3.1. Assumptions
This manual assumes that you are using a Danfoss Interbus Option in conjunction with a Danfoss FC 300 Automation Drive. It is also assumed that your
master is a PLC or PC that is equipped with a serial communication card supporting all the Interbus communication services required by your application,
and that all requirements stipulated in the Interbus standard as well as those set up in the Drivecom frequency converter Profile and its company-specific
implementation, as well as those pertaining to the VLT frequency converter are strictly observed as well as all limitations therein fully respected.
2.4.1. Hardware
This manual relates to the Interbus option type no. 130B1211.
2.5.1. Background Knowledge
The Danfoss Interbus Option is designed to communicate with any master abiding by the Interbus standard. It is therefore assumed that you have full
knowledge of the PC or PLC you intend to use as a master in your system. Any questions pertaining to hardware or software produced by any other
manufacturer are beyond the scope of this manual and are of no concern to Danfoss.
If you have questions about how to set up master-to-master communication or communication to a non-Danfoss slave, please consult the appropriate
manuals.

3. How to Install
3.1.1. Cabling
The Interbus network topology is based on a logical ring structure, implemented in a one-cable structure, making a physical bus structure with a bit rate
of 500 kbps.
Interbus supports networks with a total cable length of up to 12.8 km, with a maximum of 400 meters between nodes.
The maximum cable length is only achievable when the bus cable has the following properties:
Impedance: 120 ohm ±20% @ 64kHz, 100 ohm ±15% @ >1 MHz.
Resistance: < 9.6 ohm/100 m
Capacity: < 60 nF/km
Cross section: minimum 0.2 mm2, corresponding to AWG 25
Cable type: twisted in pairs, 3 x 2 wires
Screening: Copper-braided screen or braided screen and foil screen
Use of the same cable type throughout the entire network is recommended in order to avoid impedance mismatch.
The Interbus option has two network interfaces, one for the incoming bus and one for the outgoing bus. Both are D-sub 9 type.

3.2.1. EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the Interbus network. Additional EMC information is
available in the FC 300 series Operating Instructions (MG33AXYY) and Design Guide (MG33BXYY).
NB!
Relevant national and local regulations, for example regarding protective earth connection, must be observed.
The Interbus 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. If the Interbus cable has to cross a motor and brake resistor cable they must cross each other
at an angle of 90 degrees.
3.3.1. Installation of Option
The Interbus option is installed in its own cabinet, designed for DIN-rail mounting.
The option is connected to the FC 302 via terminal X22 on the option to terminal 68 and 69 on the frequency converter. Screened cable is recommended
(120 cm cable supplied with frequency converter).

4. How to Configure the System
4.1.1. Configure the Interbus Network
This section describes how to set up Interbus communication between a Danfoss FC 300 frequency converter and the Phoenix Interbus CMD G4.
4.1.2. Configuring of the CMD and FC 300
The first step is to connect all Interbus slaves to the master and power
up all units. Start the IBS CMD software and choose a new project from
File and New. The screen should now look like this:
The next step is to read the slaves into the bus system. Click on Config-
uration frame and click on the right mouse button. Select Read In (from
memory).
The state will be changed from Offline to Online when the Read In is
finished. Please look at the bottom of the screen. After the Read In, CMD
will indicate each VLT frequency converter with a DriveCom symbol, a
station number and an ID number.
The next step is to configure the Interbus system. This is done by clicking
on the VLT symbol and pressing the right mouse button. Select:
Descrip-
tion
.
Here it is possible to type in a Station name, Device name and a Device
number. Click on:
Parameter Channel .
For message length transmit and receive enter 246 byte and select Get-
OD (long format). The message length now corresponds to the internal
buffer in the VLT frequency converter. Get-OD (long format) means that
the master will read the English parameter description text from the VLT
frequency converter. Press OK twice.

4.1.3. Setting up PCP Communication
Via the CMD tool it is possible to read and write to parameters, and read
the English parameter text of each parameter.
To start PCP communication you must be in Monitor state.
Click on the station number and click on the right mouse button and
choose: Device
Parameterization .
The dialog box will now show Danfoss, VLT FC 300, Profile: 21.
In order to be able to read all parameters into the frequency converter,
select:
Device and Read Parameter List .
The CMD tool will now start reading all parameters, which takes 3-4 mi-
nutes.
When all parameters have been read, CMD will show the first parameter
55F1hex Par. 1 at the first row.
55F1hex corresponds to 22001dec.
This means that all FC 300 parameters can be accessed simply by adding
22000dec to the FC 300 parameter.
For example if you want to write to par. 3-41
Ramp 1 ramp up time , you
must write to 22341dec (5745hex).
The CMD tool can only indicate parameters using hexadecimal numbers.
The two first indexes are for handling the “Max Torque Limit” (par. 4-16
and 4-17) when running Custom Telegram 1.
If you want to change the value of par. 3-41 Ramp 1 ramp up time to 10
sec you must write 1000 in column next to index 5745 Hex.
You have to enter 1000 because par. 3-41 has a conversion index of -2
(= 0.01). Highlight the row and click on F5 Write Value.
The ramp up time in par. 3-41 has now been changed to 10 sec.
To activate the new settings with PCD, the CMD needs to read the con-
figuration from the VLT frequency converter again.
Click on the controller board and select Process data. The Process data
should now be 64 bits, corresponding to 4 words: control word, reference,
PCD 1 and PCD 2.

4Analogue input Reads out analogue input 53 as an absolute value. Term.53 can work as a voltage (0-10V) or
a current (0-20mA) input, depending on the setting of S201.
S201=0 voltage, S201=1 current.→→
NB!
If the connection to the Interbus master is lost, all outputs on the Interbus option are set to 0.
NB!
Setting par. 8-10 to [1]
PROFIdrive profile , enables the Drivecom Profile on the Interbus option, i.e. Control word and Status word are
interpreted as Drivecom.
Setting par. 8-10 to [0]
FC Profile will enable the FC profile on the frequency converter.
See section
How to Control the FC 300 for more information on the different profiles.
NB!
If the Interbus option is powered up without connection to a FC300 frequency converter, it will run Standard Telegram 1. This means
that it will not be possible to use any I/O’s.
Examples:
Setting the torque limit in PCD 4 (master slave):
→
Conversion index is -1.
500hex = 1280dec = 128% torque.
Reading the analogue input in PCD 4 (slave master):
→
Conversion index is -3.
3456dec = 3,456 volt.
