Safety and operating instructions

for drive power converters

1.General

During operation, drive power converters may, depending on their protection class, have live, bare, moving or rotating parts or hot surfaces.

Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of serious personal injury or material damage.

Further information can be found in this documentation.

All transportation, installation commissioning and maintenance work must be carried out by qualified personnel (compliant with IEC 364 or CENELEC HD 384 or DIN VDE 0100 and IEC 664 or DIN VDE 0110 and national accident prevention regulations).

For the purposes of these basic safety instructions, qualified personnel are persons who are familiar with the assembly, installation, commissioning and operation of this product and who have the relevant qualifications for their work.

2. Proper use in Europe

Drive power converters are components intended for installation in electrical systems or machines.

When installed in machines, the drive power converter must not be commissioned (i.e. commencement of the proper use) until it has been ensured that the machine meets the provisions of the EC Directive 2006/42/EEC (Machinery Directive); EN 60204 must also be complied with.

Commissioning (i.e. implementation of the proper use) is only permitted if the EMC directive (2004/108/EEC) is complied with.

Drive power converters with a CE label meet the requirements of the Low Voltage Directive 2006/95/EEC. The stated harmonized standards for drive current inverters are used in the declaration of conformity.

Technical data and information for connection conditions can be found on the rating plate and in the documentation, and must be complied with.

The drive power converters may only be used for safety functions which are described and explicitly approved.

3. Transport, storage

Information regarding transport, storage and correct handling must be complied with.

4. Installation

The installation and cooling of the equipment must be implemented according to the regulations in the corresponding documentation.

(as per: Low Voltage Directive 2006/95/EEC )

The drive power converter must be protected against impermissible loads. Especially during transport and handling, components must not be deformed and/or insulation distances must not be changed. Touching of electronic components and contacts must be avoided.

Drive power converters have electrostatically sensitive components, which can be easily damaged by incorrect handling. Electrical components must not be mechanically damaged or destroyed (this may cause a health hazard!).

5. Electrical connection

When working on live drive power converters, the applicable national accident prevention regulations must be complied with (e.g. BGV A3, formerly VBG 4).

The electrical installation must be implemented as per the applicable regulations (e.g. cable cross-section, fuses, earth lead connections). Further instructions can be found in the documentation.

Information regarding EMC-compliant installation – such as shielding, earthing, location of filters and installation of cables – can be found in the drive power converter documentation. These instructions must be complied with even with CE marked drive power converters. Compliance with the limit values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine.

6. Operation

Systems in which drive power converters are installed must be equipped, where necessary, with additional monitoring and protective equipment as per the applicable safety requirements, e.g. legislation concerning technical equipment, accident prevention regulations, etc.

The parameterisation and configuration of the drive power converter must be selected so that no hazards can occur.

All covers must be kept closed during operation.

7. Maintenance and repairs

After the drive power converter is disconnected from the power supply, live equipment components and power connections should not be touched immediately, because of possible charged capacitors. Observe the applicable information signs located on the drive power converter.

Further information can be found in this documentation.

These safety instructions must be kept in a safe place!

1 Introduction

1.1 General information

This AS Interface documentation is valid for the NORDAC SK 300E, SK 500E, SK 700E series and for SK 750E.

NORDAC frequency inverters can be equipped with various modules for parameterisation or control. A slot is provided for this in the basic device. As delivered, there is a blank cover at this location, which must be replaced by the DeviceNet technology unit.

1.2 The bus system

The ActuatorSensor Interface (AS-Interface) is a bus system for the lower field bus level. The transmission

principle is a single master system with cyclical polling. A maximum of 31 slaves (or 62 A/B slaves in the extended address region) can be operated on an up to 100m long unshielded two-wire cable in any network

structure (tree/line/star). For the AS interface, since the Complete Specification V2.1, a differentiation has

been made between Standard Slaves and A/B Slaves. This version includes the doubling of the number of slaves to 62. This is done by the double-assignment of addresses 1-31 and their designation as "A Slave" and "B Slave". A/B Slaves are designated by the ID code A, and therefore can be uniquely identified by the Master.

NORD AS Interface Modules type SK TUx-AS1 are standard slaves which correspond to the slave profile

S-7.4. They can be administered by masters whose profile at least corresponds to class M4 (in some cases M3 is sufficient).

NORD AS Interface Modules type SK TUx-AS3 are standard slaves which correspond to the slave profile S-7.A. They can be administered by masters whose profile at least corresponds to class M4.

The S-7.4 profile describes the function for the transfer of bit strings and the bi-directional data communication. Modules with profile S-7.A (SK TUx-AS3) use the extended address range, however transfer of strings is not possible.

Type SK TUx-AS1 and -AS3 modules can be jointly operated within an ASi network as of version 2.1 (Master profile M4) with observance of the allocation of addresses (see example).

Permissible

Standard slave 1 (Address 6)

A/B-Slave 1: (Address 7A) A/B-Slave 2: (Address 7B)

Standard slave 2 (Address 8)

The AS interface cable (yellow) transmits data and energy while a second two-wire cable (black) can be used for a low auxiliary voltage (24V). Addressing is implemented via the master, which can also provide other management functions, or via a separate addressing device. The transfer of the 4 Bit reference data (in each direction) is performed with effective error protection for standard slaves with a maximum cycle time of 5ms. Due to the the correspondingly high number of participants, for A/B slaves the cycle time (max. 10ms) is doubled for data which is sent from the slave to the master. Extended addressing procedures for the transmission of data to the slave

The bus system is completely defined in the AS-Interface Complete Specification and is standardised as per

EN 50295, IEC62026t.

also cause an additional doubling of the cycle time to max. 21ms.

2.1 NORDAC SK 500E

By the use of various modules for display, control and parameterisation, the NORDAC SK 5xxE can be easily adapted to various requirements.

Alphanumerical display and operating modules can be used for simple commissioning. For more complex tasks, various connections to a PC or an automation system can be selected.

The technology unit (Technology Unit, SK TU3-…) is connected externally to the front of the frequency inverter and is therefore easy to access and replace at any time.

In the delivery condition, without the technology unit, 2 LEDs (green/red) are visible externally. These signal the actual device status.

The green LED indicates that the mains voltage is present and operational, while a flashing code that increases in speed shows the degree of overload at the frequency inverter output.

The red LED signals actual error by flashing with a frequency which corresponds to the number code of the error (Manual BU 0500 Section 6).

2.5 Description of connections to the AS interface module

SK TU1- / TU3-AS1

By means of the AS interface cable and the AS interface master the sensors and actuators are connected to the automation device via the AS interface module. To connect an SK TU1 / TU3-AS1 module to an AS interface network, special connecting accessories must be used. An AS interface cable with an M12 connector and open cable ends is required in order to connect to the Phoenix terminals of the SK TU1 / TU3-AS1.

SK TU2-ASx

To connect the SK TU2-ASx module, M12 components (socket - plug) are used on both sides. Two individual cables with a cable branch for the PWR connection and a second cable branch for the AUX connection can be used, or by the use of a combined cable branch module both connections (AUX and PWR) can be made by means of a cable to the PWR connector.

The wire colours and the assignment of pins for the M12 components is as follows:

2.5.1 Connection of the AS interface bus cable

The yellow unshielded AS interface cable (profile cable) is a rubberised 2-core cable, which connects the AS interface module to the AS interface network. This cable provides

AS-i (+)

both the power supply to the sensors and actuators as well as the transfer of data between the AS interface master and the connected slaves. When connecting to the terminals,

AS-i (-)

care must be taken that the wires are connected to the correct colours in order to prevent incorrect polarity. A separate AS interface cable should be used for each AS interface conductor.

AS Interface connection PWR:

rubberised 2-wire profile cable

• AS-i (+) If the standard cable is used, this is the brown wire.

• AS-i (-) If the standard cable is used, this is the blue wire.

The AS interface bus cable is connected to the PWR AS-i (+) and PWR AS-i (-) terminals. For the AS interface module SK TU1 / TU3-AS1, terminals 1 and 2 are on connector 2 (see Section 2.1.2 / 2.2.2).

On the AS interface module SK TU2-ASx, the wire to AS-i (+) must be wired to pin 1 of the PWR connector and AS-i (-) to pin 3 (see Section 2.3.2).

2.5.2 Connection of the AS interface AUX power supply

The black cable is used for the power supply to the sensors. The AS interface supply cable is connected to the AUX 24V and AUX GND terminals. The corresponding connection terminals on the particular AS interface module are illustrated in Sections 2.1.2 / 2.2.2 / 2.3.2.

The AS interface modules have multiple supply terminals. These terminals are interconnected internally.

24V power supply AUX:

• AUX 24V : If the standard black cable is used, this is the brown wire.

• AUX GND : If the standard black cable is used, this is the blue wire.

2.5.3 Connection of the AS interface sensors and actuators

For the SK TU1/TU3-AS1 module the sensors and actuators are connected to connector 1 via terminals 3 to 8 (see Section 2.1.2 / 2.2.2 ). On the SK TU2-ASx module the connection is made via the I/O sockets 1 and 2. The corresponding pin assignment is illustrated in Section 2.3.2 . The connecting cables should be laid separately from the energy cables and kept as short as possible.

I/Os for sensors and actuators:

• Dig In 1-4 : digital inputs 1-4 for connection to the sensors

• Dig Out 1-2 : digital outputs 1-2 for connection to the actuators

2.5.4 Connection examples to SK TU2-ASx for sensors and actuators

In the following, 4 connection combinations to the SK TU2-ASx module for sensors and actuators by means of standard connector systems (M12 components) are illustrated. The illustrations in a) and b) refer to the connection of several sensors / actuators to a single I/O socket. Of course, two sensors can be each connected to a separate I/O socket. Suitable connector systems are e.g. those from the firm Murr Elektronik:

a) 1 sensor: The sensor can be connected directly to the I/O sockets by means of 4-pin M12 plugs.

b) 1 Sensor + 1 Actuator: Use of a 4-pin M12 – M12 / Y-connection or T connector.
