Decentralised frequency inverters with application-orientated configuration With many years of experience in the field of electronic drive technology NORD has also produced decentralised drive technology with frequency inverters since the end of the 1990's. The SK 200E series is now the 3rd generation of decentralised frequency inverters and the scaling of the series has been structured for economy, in order to cover the specific requirements of a wide range of customers. 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.

Product Series

Conveying applications

Characteristics:

Separate voltage levels 400 V/24 V, e.g. for separate operation of bus system/control level and power

Adjustable brake control with integrated rectifier

No processing of analogue values required as bus control is used frequently

Pump/fan applications

Characteristics:

Speed setpoints/process signals via analogue input, e.g. pressure sensors

“Stand alone” operation for single drives or mobile equipment

No motor brake control required

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.

Safety function "Safe stop"

The safety function "Safe stop" or STO-Safe Torque Off is a very practical and efficient method of preventing a motor from restarting, as required by the relevant standards. This prevents injury to personnel working in the vicinity of the rotating drive.

Variable configuration

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.

Customer unitsApplication-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)

PotiAdapterFor direct control, a convenient switch (left/right) and potenti-ometer unit can be implemented with the PotiAdapter. This is a very practical solution for pumps.

Tunneling of parameter data via the system bus

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.

NORD CONNORD CON is the free operating software for controlling, parameterisation and diagnostics of all NORD frequency inverters.

ControlThe 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.

ParameterisationBy 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.

DiagnosisThe 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.

SK 230E: basic variant of SK 200E + AS interface on board + “Safe stop”

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).

Device configuration

Parameterisation with dip-switchesVarious 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 settingThe 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 EEPROMAll 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.

SK 2x0E in Size 4 and SK 2x5E1 RS 232 diagnostic interface

RJ 12 interface for a connecting cable to a SimpleBox, ParameterBox or PC/laptop (NORDCON) for control, operation, parameterisation and diagnostics.

2 Status-LEDs digital inputs and outputsExternally visible LEDs to display the current status of digital inputs and outputs. Very helpful for the drive status diagnostics.

3 Potentiometers for speed setpoint and ramp, status LED for inverter and AS-iThe status of the frequency inverter (ready for operation/fault) is visible from the outside. With the integrated AS interface option, a message is also displayed here. In addition, there are two potentiometers for permanently setting a setpoint (e.g. speed setpoint and associated ramp).

Picture shows SK 2x5E

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. The diagnostic tools for the SK 2xxE are easily visible and accessible behind a transparent screw-on cover.

NORD Electronic DRIVESYSTEMSDrive electronics produced in-house

NORD Electronic DRIVESYSTEMS, a subsidiary of Getriebebau NORD in Bargteheide, has had a productionfacilityinAurichsince1984.Attheendof 2005 the new factory in Aurich / Schirum started operation. Here, 110 employees produce driveelectronics such as frequency inverters, decentralised drive technology and servo controllers. The products are produced for sale throughout the world by Getriebebau NORD.

Automatic high voltage testing system

Automatic assembly of circuit boards

"One Piece flow" in the modern assembly lineThe production process is divided into two main sections. One section is PCB production. Here,electronic components are positioned on a printed circuit board, soldered and subjected to a function test. In the second stage, the devices are assembled. This stage is completed with a quality inspection. Then the finished products are sent for dispatch. In combination with modern, efficient production technology, the strategy of great depth of production ensures a high delivery performance. Standard frequency inverters are supplied from stock.
