1. Safety Note - FC 300 Interbus FC 300 Interbus Operating Instructions

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

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 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.

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.

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. 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.

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.

1.2.2. Warning Against Unintended Start

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 stop key [STOP/RESET] must always be activated; following which data can be modified.

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.

Please refer to the relevant Operating Instructions for further safety guidelines.

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 communication 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.

FC 300 Interbus Operating Instructions

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. How to Install FC 300 Interbus Operating Instructions

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).

FC 300 Interbus Operating Instructions

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 Configuration 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:

Description

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-

4. How to Configure the System

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 minutes.

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 configuration 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.

FC 300 Interbus Operating Instructions

5.2.1. The Drivecom State Machine

The state machine describes the device status and the possible control sequence of the frequency converter. A status represents a specific internal and external response. By means of device control commands and/ or internal events, the status can be changed and a control sequence thus executed. The current status can be read out via the frequency converter’s status word.

The flow chart to the right and the following explanation may help to understand the principle: To change from state A to state B, the condition

“Control word bit 1” has to be set to 0. This causes the transition 0 to be executed. In state B the status word is: xx01H.

FC 300 Interbus Operating Instructions 6. How to Access the FC 300 Parameters

6. How to Access the FC 300 Parameters

6.1. PCP Communication

For read and write of FC 300 parameters, the Interbus Peripherals Communication Protocol (PCP) channel has to be used.

The Danfoss FC 300 Interbus option supports the following services:

Initiate: Establish connection between master and the FC 300.

Abort: Cancel connection between master and FC 300.

Read: Read FC 300 Parameters.

Write: Write FC 300 Parameters.

Get Object description: Both short and long are supported.

Identify: Identification of the FC 300 to the Master.

The following entries must be made in the Master for PCP communication:

Communication reference

Transmit buffer length

Receive buffer length

Supported service request

Supported service response

246

80 30 00 hex

00 00 00 hex

All parameters in the FC 300 are mapped to the Danfoss specific objects, starting from object 22000 = 55F0hex.

The first object is 22001 (55F1hex), which corresponds to par. 0-01.

22002 corresponds to par. 0-02 and so on.

This means that all parameters can be accessed by using PCP communication, just by adding 22000D to the FC 300 parameter.

To access FC 300 objects for reading and writing, it is necessary to set up the correct data size and index for the particular parameter.

The option board can provide the complete list of objects to the user by using the GET OD command.

Alternatively the user can set up the command for the object manually.

8.1.1. Warning and Alarm Messages

There is a clear distinction between alarms and warnings. When there is an alarm, the frequency converter will enter a fault condition. After the cause for the alarm has been cleared, the master will have to acknowledge the alarm message before the frequency converter can start operating again. A warning, on the other hand, may come when a warning condition appears, then disappear when conditions return to normal, without interfering with the process.

Warnings

Warnings within the frequency converter are represented by a single bit within a warning word. A warning word is always an active parameter. Bit status

FALSE [0] means no warning, while bit status TRUE [1] means warning. Any bit change in the warning word will be notified by a change of bit 7 in the status word.

Alarms

Following an alarm message the frequency converter will enter Fault condition. Only after the fault has been alleviated and the master has acknowledged the alarm message by setting bit 7 in the control word, will the frequency converter resume operation. Alarms within the frequency converter are represented by a single bit within an alarm word. An alarm word is always an action parameter. Bit status FALSE [0] means no fault, while bit status

TRUE [1] means fault.
