5 Product Series Decentralised frequency inverters with application-orientated configuration Based on several years of experience in decentralised drive technology, NORD launched the SK 200E product series in To meet the application requirements of the widest number of customers, the product range is offered as a series of modular and graded components that together maintain a cost effective drive solution. In this way, the customer has to only invest in those technical features that are specifically required, with the benefit that the drive solution is optimally matched to the application. Technical configuration in application areas: When considering application sectors for decentralised drive technology, conveying and pump/fan applications appear to be predominant. This product series was specially designed to economically meet these varied technical requirements. SK 2x0E pump/fan applications Characteristics: Speed setpoints/process signals via analogue input Stand alone operation for single drives or mobile equipment No motor brake control required SK 2x5E conveying applications Characteristics: Separate voltage levels 400 V/24 V, e.g. for separate operation of bus system/control level and power Adjustable brake resistor control with integrated rectifier No processing of analogue values required as bus control is used frequently SK 200E SK 210E KW SK 220E SK 230E SK 205E SK 215E KW SK 225E SK 235E F 3020 GB 5

12 Variable configuration Customer Units Application-specific interfaces in the inverter allow communication via field bus systems (Profibus, CANopen, DeviceNet) or control signals to be added (analogue and digital input/output signals) Braking resistors As standard, the inverters have an integrated brake resistor to divert generated energy. Depending on the level of such energy, internal or external brake resistors can be used for energy conversion. Internal brake resistor PotiAdapter For direct control, a convenient switch (left/right) and potentiometer unit can be implemented with the PotiAdapter. This is a very practical solution for pumps. External brake resistor 12 F 3020 GB

18 Technology Units Variable mounting For the SK 200E product series, optional Technology Units are available, which can be mounted directly on the device or separately on the machine frame or other plant components. Communication systems both with and without connection facilities for sensors, actuators and control modules are available for all current applications. As standard, they have protection class IP55 but are optionally available as IP66. The IP66 variant comes with the extension...-c in its type designation. Tunneling of parameter data via the system bus Field bus (e.g. Profibus) System bus Technology Unit mounted directly on the FI The bus Technology Unit of the SK 200E provides user-friendly and economic configuration of the drive systems in the field. As the technology units are designed as bus system with gateway functionality, several units can be addressed. Up to 4 frequency inverters and the bus Technology Unit can be linked with the standard integrated system bus. Therefore the connection to the host bus system is made at a single point. However, all data sets can be accessed by tunneling of the parameter data. Both the Technology Unit and the data sets of each of the connected SK 200E devices can be accessed via the RS 232 interface. Technology Units for wall mounting 18 F 3020 GB

20 Technology Units I/O extension With the external I/O units, arbitrary sensor and actuator signals can be included in the decentralised drive structures. These are transferred to the frequency inverter via the system bus. There these can be used for a drive function or forwarded to a host bus system (e.g. Profibus). SK 2x5E as an independent system For independent applications, the SK 200E can be equipped with options which only require a power connection (e.g. 3~ 400V). For this, a power supply or a control element - the PotiBox - can be selected as an addition. 24V power supply This generates the internal control voltage (24V) from the available supply voltage (115V / 230V / 400V). A separate control cable is not necessary. An analogue input is available for the specification of setpoint values.

23 NORD CON software NORD CON NORD CON is the free operating software for controlling, parameterisation and diagnostics of all NORD frequency inverters. Control The frequency inverted can be manually operated by means of a software window with all the operating elements of a SimpleBox. An enable signal with specification of setpoint values can be given. The parameter settings can be adjusted and read parameters (information and error messages) can be viewed. Users therefore have a supporting aid for each commissioning. Parameterisation By means of a convenient overview the user can view and adjust each available parameter. By means of am appropriate printing option, parameter lists are generated in printed form either completely or with amended values. The finished data sets can be saved on the PC/laptop and archived for future use. Diagnosis The NORD CON oscilloscope function is a simple but very useful instrument for the optimal adjustment of drive systems. By means of line graphs, all drive characteristics (current, torque, etc.) can be recorded and analysed. With these results, application-relevant settings can be fine-tuned to enable optimum operation. This is useful, e.g. for regulating the brake control or for lifting gear functions. F 3020 GB 23

28 AS interface connection with M12 plug connectors Modern automation systems have a wide range of requirements, so that a suitable bus system and drive components must be selected in order to ensure efficient implementation. For the lower field level, the AS interface is a cost-effective solution which enables the networking of binary sensors and actuators. Special versions of the SK 200E product series, which provide an appropriate solution by means of an AS interface, are available for this price-sensitive area. The supply voltage (power) is via appropriate terminals according to the version (1~/3~, 115/230/400V). The control voltage of the inverter is supplied separately. For the control unit of the inverter and the AS interface, the supply is via the (yellow) AS interface cable. This eliminates the need for an additional AUX cable (black). Power (115V/230V/400V) AS Interface incl. 24V supply for SK 2xxE Versions with AS-i on board: SK 220E: basic variant of SK 200E + AS interface on board SK 230E: basic variant of SK 200E + AS interface on board + Safe stop Versions with AS-i on board: SK 225E: basic variant of SK 205E + AS interface on board SK 235E: basic variant of SK 205E + AS interface on board + Safe stop SK 200E SK 210E KW SK 220E SK 230E SK 205E SK 215E KW SK 225E SK 235E 28 F 3020 GB

29 To connect the AS-i cable and any initiators, appropriate M12 plug connectors can be provided exworks. These are colour-coded in order to provide a definite assignment of functionalities in the field. The following versions can be selected as options. AS interface connection AS interface (24 V power supply for SK 225E and SK 235E via AS interface) Optional M12- plug connector (yellow) for AS-i: SK TIE4-M12-AS1 (Part No ) Connection for AS interface and initiators AS interface (24 V power supply for SK 225E and SK 235E via AS interface) Initiators (max. 2x M12 possible, each with 2x digital inputs) Optional M12- plug connector (yellow) for AS-i: SK TIE4-M12-AS1 (Part No ) Optional M12 plug connector (black) for I/O: SK TIE4-M12-INI (Part No ) F 3020 GB 29

30 Device configuration Parameterisation with dip-switches Various functions, e.g. the regulation characteristics of the frequency inverter (U/f characteristic curve/ ISD control) can be simply set by means of directly accessible DIP switches. This enables easy selection of the functions even without a parameterisation tool. The settings made via DIP switches are also active when the memory module is not plugged in. If the EEPROM is plugged in, the DIP switch settings overwrite the relevant parameters. IT network setting The filtering of the frequency inverter can be adjusted with this jumper. This makes it possible to use the inverter in an IT voltage network, or under low leakage current operation (ground-fault circuit). Plugg-in EEPROM All parameters which can be changed with the Control Box or the NORDCON software are stored in a plug-in EEPROM. This module can be easily transferred to different devices to enable rapid commissioning or quick replacement. 30 F 3020 GB

31 Status and diagnostic cockpit Direct-access to diagnostic tools A great advantage of decentralised drive systems is the location of the frequency inverter near to the drive in large plant structures. Direct access to the drive for monitoring and diagnostics is therefore a great benefit.

42 NORD Electronic DRIVESYSTEMS Drive electronics from Aurich NORD Electronic DRIVESYSTEMS, a subsidiary of Getriebebau NORD in Bargteheide, has had a production facility in Aurich since At the end of 2005 the new factory in Aurich / Schirum started operation. Here, 110 employees produce drive electronics such as frequency inverters, decentralised drive technology and servo controllers. The products are produced for sale throughout the world by Getriebebau NORD Automatic assembly of circuit boards High speed SMD assembly plant The production process is divided into two main sections. The first is the production of PCBs. Electronic components are mounted on a board / PCB, soldered and subjected to a functional inspection. With this the starting material for the second stage, the final assembly, is complete. The final assembly ends with the corresponding inspection of the device. Then the finished products are sent for dispatch. The strategy of great depth of production, coupled with modern and efficient production methods has a great influence on the delivery performance, which at present is 98%. Standard frequency inverters are supplied from stock. "One Piece flow" in the modern assembly line Automatic high voltage testing system 42 F 3020 GB
