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.

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. The information in this manual is based on a minimum firmware version 1.16 of the option, and version 5.84 of the FC 300. If your option or drive has an earlier version, some of the functions may not be supported. 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.

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: 3 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. MG.33.H4.02 - VLT is a registered Danfoss trademark 7 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. 3 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 Interbus Option). The RS-485 termination switch on the FC 300 (BUS-TER.) must be set to "ON".

Please refer to the Parameters chapter for more details of each parameter. 3 3.5.2 Basic Communication Parameters These parameters are necessary to establish communication between the Interbus option and the FC 300. Parameter 8-01 8-32 8-35 Parameter name Control Site FC Port Baud Rate Minimum Response Delay Setting [0] Control Word only [4] 38400 baud 1 ms The Interbus option is capable of operating with two different telegram-types for process data: · Standard Telegram 1, is a telegram with 4 PCD's. The two first PCD's is for holding Control word and reference for Master-to-slave comm. And Status word and Main Actual Value for Slave-to-master comm. The last two PCD's (3 and 4) is reserved for future use, and contains only 0's. · Custom Telegram 1, is a telegram with 4 PCD's that in addition also holds information on digital and analogue I/O's and torque limit. 3.5.3 Communication Settings The Interbus option has an on board non volatile memory that stores the last used telegram type. This setting will be used, if the Interbus option can not establish communication to the FC 300 within the first three seconds after powerup (e.g. FC 300 not powered up). This does secure that an unpowered FC 300 will not course a stopped Interbus system. The Interbus option will set a bit in the status word to indicate this state. To change the communcation setting from one telegram type to another, a complete power down-power up of the Interbus option and of the drive is needed. Only this will change the communication settings on the Interbus option. For the first time powerup, the Interbus option will use Custom Telegram 1 as a default if no FC 300 is connected.

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.

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.

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: 6 Communication reference Transmit buffer length Receive buffer length Supported service request Supported service response 2 246 246 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.

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. 48 MG.33.H4.02 - VLT is a registered Danfoss trademark FC 300 Interbus Operating Instructions 8 Troubleshooting Example 1: Par. 3-00 = "-Max - +Max" Par. 3-03 "Max reference" = 1500 RPM Reference send = 1500hex (5376 dec) The output can be calculated as: 8 Example 2: Par. 3-00 = "Min - Max" Par. 3-02 "Min reference" = 100 RPM Par. 3-03 "Max reference" = 1500 RPM Reference send = 1500hex (5376 dec) The output can be calculated as: 8.2.1 LED Behaviour Stopped Interbus Comm. In case of stopped Interbus communication, a particular behaviour of the "FC bus" LED can be observed. The behaviour and conditions are as follows: · Interbus communication is stopped by the Master · The Interbus option is powered-up while the frequency converter is powered off · The "FC bus" LED is flashing, indicating baud-rate search · The frequency converter is powered-up · The "FC bus" LED turns off, indicating baud-rate found and no FC-bus communication. NB! This might be interpreted as failing FC-bus communication, but in fact, the FC-bus comm. is inactive due to the stopped Interbus comm. This is not a failure.
