WARNING

HIGH VOLTAGE

The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor, frequency converter, or €eldbus may damage the equipment, cause 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.The frequency converter must be disconnected from mains before carrying out repair work. Check that the mains supply has been disconnected and that the necessary time has passed before removing motor and mains plugs.

2.The off-command on the serial bus does not disconnect the equipment from mains and should not be used as a safety switch.

3.Correct protective earthing or grounding 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.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.

MG92C202

Safety	MCA 123 POWERLINK

1.The motor can be brought to a stop with bus commands while the frequency converter is connected to mains. These stop functions do NOT provide protection against unintended starts.

2.While parameters are being changed, there is a risk that motor starts.

3.Electronic faults in the frequency converter and cease of

•

temporary overload faults in supply mains, or

fault in the motor connection

can cause an unintended start.

WARNING

ELECTRICAL HAZARD

Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.

2.1.5 Topology

The POWERLINK module features a built-in POWERLINK controlled node and a two-port hub. This module enables the possibility for connecting several POWERLINK options in a line topology. If more than eight frequency converters are connected in line, it requires special attention towards the timing in the network.

It is important in a POWERLINK system, that the connection is done correctly.

MG92C202

How to Install	MCA 123 POWERLINK

2 2

Illustration 2.19 Line Topology

Take care that following design rules are followed

1.Do not connect any non-POWERLINK device (e.g. a PC) to any free port as to avoid malfunction of the complete POWERLINK network.

2.In a line topology, power all frequency converters either by mains or by a 24 V DC option card, for the built-in POWERLINK slave controller to work.

3.To achieve interference-free operation of the Ethernet, observe the following EMC precautions. The correct handling of the motor cable screen is vital for the overall performance of the system. If the rules are not followed, it leads to loss of the control and malfunction of the system. The Ethernet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high frequency noise between the cables. Normally, a minimum 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, or if frequency converters with a bigger power size are installed. More information can be found in the norm IEC 61000-5-2:1997.

<![if ! IE]>

<![endif]>130BD147.10

4.When crossing of cables is unavoidable, the Ethernet cable must cross motor and brake resistor cables at an angle of 90°.

5.Always observe relevant national and local regulations, for example regarding protective earth connection.

2.1.6 EMC Precautions

To achieve interference-free operation of the Ethernet, observe the following EMC precautions. Additional EMC information is available in the VLT® AutomationDrive Design Guide.

NOTICE

The correct handling of the motor cable screen is vital for the overall performance of the system. If the rules are not followed, it can lead to loss of the control and malfunction of the system.

3 How to Configure

3.1 Configure the Parameters

3.1.1 IP Settings

All IP-related parameters are located in parameter group 3 3 12-0* IP Settings: The parameters are all set to POWERLINK

standard values, so no setting is needed. In POWERLINK, the parameter 12-00 IP Address Assignment is fixed to the option "From node ID". The IP address follows the setting in parameter 12-60 Node ID, so that the IP address is 192.168.100.xxx, where xxx is the node ID. For

parameter 12-02 Subnet Mask, the IP addres is fixed to 255.255.255.0 and cannot be changed.

The POWERLINK option offers two ways of node ID assignment via parameter or DIP switch.

3.1.2 Ethernet Link Parameters

Parameter group 12-1* Ethernet Link Parameters holds

Ethernet Link information:

Parameter 12-10 Link Status

Parameter 12-11 Link Duration

Parameter 12-12 Auto Negotiation

Parameter 12-13 Link Speed

Parameter 12-14 Link Duplex

Each port has unique Ethernet link parameters.

Parameter 12-10 Link Status displays Link or No Link according to the status of the present port.

Parameter 12-11 Link Duration displays the duration of the link on the present port. If the link is broken, the counter is reset.

Parameter 12-12 Auto Negotiation is a feature that enables two connected Ethernet devices to select common transmission parameters, such as speed and duplex mode. In POWERLINK, this feature is fixed to OFF and cannot be changed.

Parameter 12-13 Link Speed - displays the link speed for each port. If no link is present, “None” is displayed. In POWERLINK, this feature is fixed to 100 MBaud and cannot be changed.

Parameter 12-14 Link Duplex - displays the duplex mode for each port.

In POWERLINK, the Link Duplex is fixed to Half Duplex, and cannot be changed.

3.2 Configure the Frequency Converter

3.2.1 VLT Parameters

Pay particular attention to the following parameters when configuring the frequency converter with a fieldbus interface.

•Parameter 0-40 [Hand on] Key on LCP. If the [Hand on] key on the frequency converter is activated, control of the frequency converter via the fieldbus interface is disabled.

•After an initial power-up, the frequency converter automatically detects whether a fieldbus option is installed in slot A. It then sets

parameter 8-02 Control Word Source to [Option A]. Adding, changing, or removing an option from an already commissioned frequency converter does not change parameter 8-02 Control Word Source. However, it causes a trip mode, and the frequency converter displays an error.

•Parameter 8-10 Control Word Pro€le. Select between the Danfoss FC Profile and the DS 402 profile. The change of parameter 8-10 Control Word Pro€le is active at the next power-up.

•Parameter 8-50 Coasting Select to

parameter 8-56 Preset Reference Select. Selection of how to gate fieldbus control commands with digital input command of the control card.

NOTICE

When parameter 8-01 Control Site is set to [2] Control word only, Bus-control overrules the settings in parameter 8-50 Coasting Select to parameter 8-56 Preset Reference Select.

•Parameter 8-03 Control Word Timeout Time to parameter 8-05 End-of-Timeout Function. The reaction in the event of a bus time-out is set via these parameters.

3.3Configure the POWERLINK Network

All POWERLINK stations that are connected to the same bus network must have a unique node address. The node address of the frequency converter can be selected via:

•Hardware switches (from version 1.12)

•parameter 12-60 Node ID

Setting the NODE Address using the Hardware Switches

Using the hardware switches, it is possible to select an address range 0–239 (factory setting 1) according to Table 3.1:

NOTICE

The switches are only read during power-up. Changes are active after the next power up, and can be read in parameter 12-60 Node ID. Note the location and sequence of the hardware switches as illustrated in Illustration 2.3.

Setting the NODE Address via parameter 12-60 Node ID

Setting the address via parameter 12-60 Node ID, is only possible if the hardware switches are set to 0 or 255 (factory setting). The address change becomes active at the next power-up. The node address has direct influence on the IP address in parameter 12-01 IP Address. If the hardware switch is set to an illegal number, the frequency converter immediately issues Warning 34 in the display, and parameter 12-69 Ethernet PowerLink Status is set to 0 (zero).
