1 General

The SK 1x5E series is based on the tried and tested NORD platform. The devices are characterised by their compact design and their optimum operational characteristics, and have uniform parametrisation.

Due to dual phase control, not only a pure motor start, but also a soft start is possible. The phase control process was selected so that the resulting harmonic torques are kept as low as possible. A comprehensive spectrum of monitoring functions rounds off the range.

Due to the numerous setting options, any three-phase synchronous motor can be controlled.

The motor starter is basically intended for a three-phase mains connection. The power range is from

0.25 kW to 7.5 kW.

This series of devices can be adapted to individual requirements by means of modular assemblies.

This manual is based on the device software specified in the version list (see P707). If the motor starter uses a different software version, this may cause differences. If necessary, the current manual can be downloaded from the Internet (http://www.nord.com/

Additional descriptions exist for optional functions and bus systems (http://www.nord.com/).

Information

Changes may also be made to the accessories that are mentioned in the manual. Current details of these are included in separate data sheets, which are listed under www.nord.com Manuals → Electronic drive technology → Techn. Info / Data sheet. The data sheets available at the date of publication of this manual are listed by name in the relevant sections (TI ...).

Accessories

under the heading Documentation →

The different versions of the device series also result in different functionality (e.g.: with integrated AS Interface or with integrated PROFIBUS DP interface).

In the simplest configuration, all of the most important parameters can be set using up to four potentiometers and four DIP switches, even without a PC or a control unit. LEDs are provided for the diagnostics of the operating status. The use of a control module is therefore not absolutely necessary.

Installation directly on a motor is typical of this device series. Alternatively, optional accessories are also available for mounting the devices close to the motor, e.g. on the wall or on a machine frame.

In order to have access to all parameters, the internal RS232 interface (access via RJ12 connection) can be used. Access to the parameters takes place via an optional SimpleBox or ParameterBox, for example.

The parameter settings modified by the owner/operator must be saved in the Flash memory of the device (P550). Otherwise the changed parameter settings would be lost when the device was switched off.

Option modules

Option modules are used to extend the functionality of the device.

These options are available as an installation variant, the so-called SK CU4-… customer unit, and also as an attachment variant, the so-called SK TU4-… technology unit. As well as the mechanical differences, the installation and attachment variants also have some functional differences.

Figure 1: Device with internal SK CU4-... Figure 2: Device with external SK CU4-...

Attachment variant

The external technology unit (Technology Unit SK TU4-…) is externally attached to the device and is therefore easy to access.

A technology unit basically requires the use of a suitable SK TI4-TU-… connection unit.

The power supply and signal lines are connected using the screw clamps of the connection unit. Depending on the version, additional connections for connectors (e.g. M12 or RJ45) may be available.

The optional wall mounting kit SK TIE4-WMK-TU also allows the technology units to be mounted away from the starter.

Built-in variant

The internal customer unit (Customer Unit, SK CU4-...) is integrated in the device. The power supply and signal lines are connected using screw clamps.

1.4 Safety, installation and operating instructions

Before working on or with the device, please read the following safety instructions extremely carefully. Please pay attention to all other information from the device manual.

Non-compliance can result in serious or fatal injuries and damage to the device or its surroundings.

These safety instructions must be kept in a safe place!

1. General

Do not use defective devices or devices with defective or damaged housings or missing covers (e.g. blind plugs for cable glands). Otherwise there is a risk of serious or fatal injuries caused by electric shock or bursting electrical components such as powerful electrolytic capacitors.

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

During operation and depending on the protection class of the devices, there may be live, bare, moving or rotating parts or hot surfaces.

The device operates with a dangerous voltage. Dangerous voltage may be present at the supply lines, contact strips and PCBs of all connecting terminals (e.g. mains input, motor connection), even if the device is not working or the motor is not rotating (e.g. caused by electronic disabling, jamming of the drive or a short circuit at the output terminals).

The device is not equipped with a mains switch and is therefore always live when connected to the power supply. Voltages may therefore be connected to a connected motor at standstill.

Even if the drive unit has been disconnected from the mains, a connected motor may rotate and possibly generate a dangerous voltage.

If you come into contact with dangerous voltage such as this, there is a risk of an electric shock, which can lead to serious or fatal injuries.

The device and any power plug connectors must not be disconnected while a voltage is applied to the device. Failure to comply with this may cause arcing, which in addition to the risk of injury, also results in a risk of damage or destruction of the device.

The fact that the status LED or other indicators are not illuminated does not indicate that the device has been disconnected from the mains and is without voltage.

The heat sink and all other metal components can heat up to temperatures above 70 °C.

Touching these parts can result in local burns to the body parts concerned (cooling times and clearance from neighbouring components must be complied with).

All work on the device, e.g. transportation, installation, commissioning and maintenance work must be carried out by qualified experts (observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 and IEC 664 or DIN VDE 0110 and national accident prevention regulations). In particular, the general and regional installation and safety regulations for work on high voltage systems (e.g. VDE) must be complied with as must the regulations concerning correct use of tools and the use of personal protection equipment.

During all work on the device, take care that no foreign bodies, loose parts, moisture or dust enter or remain in the device (risk of short circuit, fire and corrosion).

Further information can be found in this documentation.

(Due to charged capacitors, the equipment may continue to carry hazardous voltages for up to 5 minutes after being switched off at the mains). Before starting work it is essential to check by measurement that all contacts of the power plug connections or the connection are voltage-free.

The electrical installation must be implemented as per the applicable regulations (e.g. cable crosssection, fuses, earth lead connections). Further instructions can be found in the documentation or manual for the device.

Information regarding EMC-compliant installation such as shielding, earthing, location of filters and routing of cables can be found in the documentation for the devices and in the technical information manual TI 80-0011

. CE marked devices must also comply with these instructions. Compliance with the limit values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine.

In case of a fault, insufficient earthing may cause an electric shock with possibly fatal consequences if the device is touched.

The device may only be operated with effective earth connections which comply with local regulations for large leakage currents (> 3.5 mA). Detailed information regarding connections and operating conditions can be obtained from the technical Information manual TI 80-0019

The voltage supply of the device may directly or indirectly put it into operation, or touching electrically conducting components may then cause an electric shock with possible fatal consequences.

All phases of all power connections (e.g. power supply) must always be disconnected.

Set-up, troubleshooting and commissioning

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

The voltage supply of the device may directly or indirectly put it into operation, or touching electrically conducting components may then cause an electric shock with possible fatal consequences.

The parametrisation and configuration of the devices must be selected so that no hazards can occur.

With certain setting conditions, the device or the motor which is connected to it may start automatically when the mains are switched on. The machinery which it drives (press / chain hoist / roller / fan etc.) may then make an unexpected movement. This may cause various injuries, including to third parties.

Before switching on the mains, secure the danger area by warning and removing all persons from the danger area.

2.1 Installation SK 1x5E

The devices are available in various sizes depending on their output. They can be mounted on the terminal box of a motor or in its immediate vicinity.

Motor-mounted version Wall-mounted version

When a complete drive unit (gear unit + motor + SK 1x5E) is delivered, the device is always fully installed and tested.

IP6x-compliant devices must be installed by NORD, since special measures have to be implemented. IP6x components that are retrofitted on site cannot ensure that this protection class is provided.

When delivered separately, the device includes the following components:

• SK 1x5E

• Screws and contact washers for mounting the motor terminal box

• Pre-fabricated cable for motor and PTC connections

The sizes of the device series only differ with regard to their possibilities for adapting to the matching motors. For example, size 1 is coordinated with motor sizes 80 – 100, and size 2 is coordinated with motor size 132. The external dimensions (envelope dimensions) of the devices are identical.

2.3 Electrical Connection

WARNING Electric shock

Dangerous voltages can be present at the mains input and the motor connection terminals even when the device is not in operation.

• Before starting work, check that all relevant components (voltage source, connection cables, connection

terminals of the device) are free of voltage using suitable measuring equipment.

• Use insulated tools (e.g. screwdrivers).

• DEVICES MUST BE EARTHED.

Information

As with other signal cables, thermistor cables must be laid separately from the motor cables Otherwise the interfering signals from the motor winding that are induced into the line affect the device.

Ensure that the device and the motor are specified for the correct supply voltage.

The housing cover must be removed from the device in order to make the electrical connection ( Section 2.1.1 "Work procedures for motor installation").

One terminal level is provided for the power connections and one for the control connections.

Temperature sensor and PTC (TF)

The PE connections (device earth) are located on the power connections for the motor and the mains, as well as on the base inside the cast housing.

The terminal strip assignments differ according to the version of the device. The correct assignment can be found on the inscription on the respective terminal or the terminal overview plan printed inside the device.

Looping of the mains voltage

2.3.1 Wiring guidelines

The soft starters have been developed for use in an industrial environment. In this environment, electromagnetic interference can affect the device. In general, correct installation ensures safe and problem-free operation. To meet the limiting values of the EMC directives, the following instructions should be complied with.

1. Ensure that all devices are securely earthed to a common earthing point or earthing rail using short

earthing cables with a large cross-section. It is especially important that each control unit which is connected to the electronic drive technology (e.g. an automatic device) has a short cable with a large cross-section, which is connected to the same earthing point as the device itself. Flat cables (e.g. metal stirrups) are preferable, as they have a lower impedance at high frequencies.

2. The bonding cable of the motor controlled by the soft starter should be connected directly to the

earthing terminal of the associated device. The presence of a central earthing bar in the control cabinet and the grouping together of all bonding conductors to this bar normally ensures safe operation.

3. Where possible, shielded cables should be used for control circuits. The shielding at the cable end

should be carefully sealed and it must be ensured that the wires are not laid over longer distances without shielding.

The shields of analogue setpoint cables should only be earthed on one side on the device.

4. The control cables should be installed as far as possible from power cables, using separate cable

ducts, etc. Where cables cross, an angle of 90° should be ensured as far as possible.

5. Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the

case of AC contactors or by free-wheeling diodes for DC contactors, for which the interference traps must be positioned on the contactor coils. Varistors for over-voltage limitation are also effective.

6. Shielded or armoured cables should be used for the load connections (motor cable if necessary).

The shielding or armouring must be earthed at both ends. The earthing should be provided directly to the PE of the device if possible.

In addition, EMC-compliant wiring must be ensured.

The safety regulations must be complied with under all circumstances when installing the

devices!

NOTICE Damage due to high voltage

The device may be damaged by electrical loads which do not correspond to its specification.

• Do not perform any high voltage tests on the device itself.

• Disconnect the cable which is to be tested from the device before performing a high voltage insulation test.

The permissible current load for the connection terminals, plugs and supply cables must be observed when looping the mains voltage. Failure to comply with this will result in thermal damage to current-carrying modules and the immediate vicinity thereof.

If the device is installed according to the recommendations in this manual, it meets all EMC directive requirements, as per the EMC product standard EN 60947-4-2.

2.3.2 Electrical connection of power unit

NOTICE

This device produces high frequency interference, which may make additional suppression measures necessary in domestic environments ( Section 8.1 "Electromagnetic compatibility (EMC)").

The use of shielded motor cables is essential in order to maintain the specified radio interference suppression level.

When the device is being connected, please note the following:

1. Ensure that the mains supply provides the correct voltage and is suitable for the current required

( Section 7 "Technical data").

2. Ensure that suitable electrical fuses with the specified nominal current range are installed between

the voltage source and the device.

3. Mains cable connection: to terminals L1-L2/N-L3 and PE (depending on device)

4. Motor connection: to terminals U-V-W

A 4-core motor cable must be used if the device is being wall-mounted As well as U-V-W, PE must also be connected. If present, in this case the cable shielding must be connected to a large area of the metallic screw connector of the cable gland.

The use of wire end rings is recommended for connecting to PE.

This configuration can also be carried out at a later date; however it can only be carried out by the manufacturer. With the operation a device which is configured for an IT network, compliance with the EMC limit value class B cannot be ensured under the conditions stated in Section 8.1.3 "EMC of device". In this case, additional interference suppression measures must be provided.

Use with differing supply networks or network types

The frequency inverter may only be connect to and operated in supply networks which are explicitly stated in this section ( Section 2.3.2.1 "Mains supply (L1, L2, L3, PE)")). Operation in deviating

network types may be possible, but must be explicitly checked and approved by the manufacturer in advance.

2.3.2.2 Motor cable (U, V, W, PE)

The motor cable must be connected properly.

2.3.2.3 Electromechanical brake

The device generates an output voltage at terminals 79 / 80 (MB+ / MB-) for actuating an electromagnetic brake. This is dependent on the supply voltage that is present in the device. The allocation is as follows:

Mains voltage / AC voltage Brake coil voltage (DC)

460 V ~ / 480 V ~ 205 V =

The assignment of the correct brake and brake coil voltage must be taken into consideration in the design with regard to the mains voltage of the device.

For the connection of an electro-mechanical brake to the terminals of the device, parameters P107 / P114 (brake application time / release time ) must be adjusted. In order to prevent damage to the brake control, parameter (P107) must contain a non-zero value.

The device must be provided with an external 24 V control voltage supply. Alternatively, an optionally available 24 V power of type SK CU4-… or SK TU4-… can be used.

The provisions in chapter 4.3 "AS Interface (AS-i)" apply to devices in which the AS interface is used.

A control unit overload caused by impermissibly high currents may destroy the unit. Impermissibly high currents occur if the actual total current that is drawn exceeds the permissible total current or if the 24 V control voltage for other devices is routed through the device. To avoid conduction through the frequency inverter, e.g. double wire end ferrules must be used.

If necessary, 24 V can be drawn from several terminals. This also includes e.g. digital outputs or a operating module connected via RJ45

The total currents which are drawn off must not exceed 200 mA (SK 175E-…-ASI: 165 mA).

The reaction time of a digital signal is approx. 4-5 ms and consists of the following:

Internal processing < 1 ms

All control cables (including thermistors) must be routed separately from the mains and the motor cables to prevent interference in the device.

If the cables are routed in parallel, a minimum distance of 20 cm must be maintained from cables which carry a voltage of > 60 V. The minimum distance may be reduced by screening the cables which carry a voltage, or by the use of earthed metal partitions within the cable conduits.

Alternative: Using a hybrid cable with shielding of the control lines.

The device can be basically started up without parameter adaptation, i.e. programming-technical aids. 4 potentiometers (P1 – P4) and a 4-pin DIP switch block (S1) are available for this. Access to P1 and P2 takes place using the diagnostics opening in the centre. This is where the status LEDs of the device are located. Potentiometers P3 and P4 and the PROFIBUS DP addressing (SK 175E-…-PBR only) are accessible by removing the cover of the device.

(SK 175E-…-PBR only)

The SK 1x5E can be easily adapted to a wide range of requirements by using function-enhancing modules for display, control and parametrisation.

Optionally available control devices from NORD or the free "NORDCON" PC software can be used for targeted adaptation of individual parameters. The right-hand diagnostic connection must be opened to access the diagnostic interface. Devices with an older manufacturing date (serial number (ID) "26P…" or less) only have the diagnostic opening in the centre. The diagnostics interface is then only accessible by removing the cover of the device.

3.1 Control and parametrisation options

Various control options are available that can be fitted directly to the device or in close proximity to it and directly connected.

Parametrisation units also provide a facility for accessing the parametrisation of the device and adapting it.

3.1.1 Control and parametrisation units, use

Access to the parameters of the SK 1x5E can take place either using the NORD CON software or with the aid of an optionally available SimpleBox or ParameterBox. Permanent parameter changes must be saved in the Flash memory of the device using parameter P550.

A SimpleBox or ParameterBox cannot be connected directly to the device, but must be connected using an RS 232 / RS 485 converter (SK TIE4-RS485-RS232, Part No. 275274603). When doing this the parametrisation unit must be connected to the converter before making the connection to the motor starter. The motor starter must be ready for operation when this takes place.

With active RS232 communication to the PC (NORD CON) or to a connected parametrisation unit, the status of the device cannot be indicated via the LEDs. In this case, the "DS" LEDs signal that communication activity is taking place by being permanently on in green. The red LED is then switched off.

The green LED can also be made to flash by adjusting potentiometer P1.

4 Commissioning

WARNING Unexpected movement

Connection of the supply voltage may directly or indirectly set the drive unit into motion. This may cause an unexpected movement of the drive unit and the machine which is connected to it. This unexpected movement may cause severe or fatal injuries and/or material damage.

Unexpected movements may be due to several causes, e.g.

• Parameterisation of an "automatic start",

• Incorrect parameterisation,

• Control of the device with an enabling signal from a higher level control unit (via IO or bus signals),

• Incorrect motor data,

• Release of a mechanical holding brake,

• External influences such as gravity or other kinetic energy which acts on the drive unit.

To avoid any resulting (mechanical blocking and/or decoupling, provision of protection against falling, etc.) In addition, it must be ensured that there are no persons within the area of action and the danger area of the system.

4.1 Factory settings

All motor starters supplied by Getriebebau NORD are pre-programmed with the default setting for standard applications with 4-pole standard motors (same voltage and power). The nominal current of the motor (see motor type plate, for example) can be set for the respective motor circuit using potentiometer P1, which has priority in the factory setting or the as-delivered condition. If parameter P130=1, the nominal current of the motor must be set in parameter P203 "Rated motor current".

It must be ensured that the hardware can essentially be configured mechanically using DIP switch block S1 and potentiometers P1 ... P4 or alternatively by adapting individual parameters. The decision concerning this is made

by setting parameter P130 ( Section 4.2.2 "Configuration").

4.2 Starting up the device

The motor starter can be started up in various ways:

For simple applications (e.g conveyor applications) by means of the DIP switches (S1) integrated

in the device (internal), the two externally accessible potentiometers P1 and P2 potentiometers P3 and P4.

b) By adapting parameters using the control and parametrisation unit (SK CSX-3H or SK PAR-3H) or

the NORD CON PC - supported software.

Attention must be paid to the setting of parameter P130 when doing this. The parameter settings are only effective if P130 = 1!

After completing the parametrisation transferred from the RAM memory to the Flash memory of the device ( P550)! Otherwise the settings that have been made will be lost again when the device is shut off.

Note: Flash memory! Approximately 100 memory cycles are possible!

4.2.1 Connection

In order to provide basic operational capability, after the device has been attached to the motor or the wall mounting kit, the power and motor lines must be connected to the relevant terminals ( Section 2.3.2 "Electrical connection of power unit").

It is also essential for the device to be provided with a 24 V DC control voltage.

Information

Control voltage

The 24 V control voltage that is required can be implemented by means of an integrated (SK CU4-24V-…) or external (SK TU4-24V-…) optional mains module or a comparable 24 V DC power source ( Section 2.3.3 "Electrical connection of the control unit").

4.2.2 Configuration

The device can be configured for the majority of operating modes by setting potentiometers (P1-P4) and DIP switches (S1). For extended functions or for diagnostic purposes it may be necessary to adjust or view individual parameters.

The basic steps for successful start-up of the motor starter are listed in the following. To begin with, it must be decided whether the start-up is to take place via DIP switches and the potentiometers, or exclusively by means of parameter setting.

The software adaptations that are made via the parameters are only taken into consideration if parameter P130 is set to a value of ( 1 ).

Any parameters that are not listed here always have an influence on the functionality of the motor starter, irrespective of the setting of parameter P130. However, they always remain in the factory setting at P130 = "0".

4.2.2.4 Overview of switch-off modes

The switch-off mode determines the start-up and shut-down behaviour of the drive.

Parameter P130 determines whether the switch-off mode should be set by means of hardware adaptation (DIP switch (S1), potentiometer (P1-P4)) or software adaptation (parametrisation of P108).

The main modes of behaviour can be set by means of hardware adaptation (factory setting).

Other settings can be made by means of parameter adaptations if there is a need for further optimisation.

4.3 AS Interface (AS-i)

This section is only relevant for device of type SK 175E-...-ASI.

4.3.1 The bus system

General information

The Actuator-Sensor-Interface (AS interface) is a bus system for the lower field bus level. It is fully defined in the AS interface Complete Specification and standardised as per EN 50295, IEC62026.

The transmission principle is a single master system with cyclical polling. Since Complete

Specification V2.1, a maximum of 31 standard slaves which use device profile S-7.0. or 62 A/B slaves that use device profile S-7.A. can be operated on a non-shielded two-wire cable up to 100 m in

length with any network structure.

The number of possible slave subscribers can be doubled by means of double assignment of addresses 1-31 and designation "A Slave" or "B Slave". A/B Slaves are designated by the ID code A, and therefore can be uniquely identified by the Master.

Devices with slave profiles S-7.0 and S-7.A can be jointly operated within an AS-i network as of version 2.1 (Master profile M4) with observance of the allocation of addresses (see example).

Permissible Not permissible

Addressing is implemented via the master, which can also provide other management functions, or via a separate addressing device.

Device-specific information

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 5 ms. Due to the correspondingly higher number of participants, for A/B slaves the cycle time (max. 10 ms) is doubled for data which is sent from the slave to the master. Extended addressing procedures for the transmission of data to the slave also cause an additional doubling of the cycle time to max. 21 ms.

The yellow AS interface cable supplies data and energy.

The motor starter is configured in such a way that no additional auxiliary voltage has to be connected. However, by adapting a jumper it is possible to configure the motor starter in such a way that the yellow AS-i cable is only used for data transmission and supplies the AS-i bus. The device itself and sensors and the like that are connected via the device are then provided with an auxiliary voltage (24 V DC) by a second two-wire cable (black). When doing this it is essential to provide the supply via a protective low voltage (PELV - Protective Extra Low Voltage).

4.3.2 Features and technical data

The device can be directly integrated in an AS interface network is parametrised in its factory settings so that the most frequently used AS-i functionality is available immediately. Only adaptations for application-specific functions of the device or the bus system, the addressing and proper connection of the supply, BUS, sensor and actuator cables need to be carried out.

4.3.3 Bus structure and topology

The AS Interface network must be set up in any form (line, star, ring and tree structure) and is managed by an AS interface master as the interface between the PLC and slaves. Additional slaves can be added to an existing network at any time, up to a limit of 31 standard slaves or 62 A/B slaves. The slaves are addressed by the master or an appropriate addressing device.

An AS-i master communicates independently and exchanges data with the connected AS-i slaves. Normal power units may not be used in the AS interface network. Only a special AS interface power unit may be used for the power supply for each AS interface connector. This AS interface power supply is directly connected to the yellow standard cable (AS-i(+) and AS-i(-) cable) and should be positioned as close as possible to the AS-i master in order to keep the voltage drop small.

In order to avoid problems, the PE connection of the AS interface power supply (if present) must be earthed.

The brown AS-i(+) and the blue AS-i(-) wire of the yellow AS interface cable must not be earthed.

WARNING

Unexpected movement due to automatic starting

In the event of a fault (communication interrupted or bus cable disconnection, the device automatically switches off, since the device enable is no longer present.

Restoration of communication may result in an automatic start and therefore, unexpected movement of the drive unit. To prevent any hazard, a possible automatic start must be prevented as follows:

• If a communication error occurs, the bus master must actively set the control bits to "zero".

Bit 3 1) Status of initiator 2 (DIN4 / C2) 1 1 Run (motor running without warning)

Parallel actuation via the BUS and the digital inputs (C1, C2) is possible. The relevant inputs are dealt with more or less as normal digital inputs. If a changeover between manual and automatic is going to take place, it must be ensured that no enable via the normal digital inputs takes place in automatic mode. This could be implemented e.g. with a three-position key switch. Position 1: "Manual left" Position 2: "Automatic" Position 3: "Manual right".

If an enable is present via one of the two "normal" digital inputs, the control bits from the bus system are ignored. An exception is the control bit "Acknowledge fault". This function is always possible in parallel, regardless of the control hierarchy. The bus master can therefore only take over control if no actuation via a digital input takes place. If "Enable left" and "Enable right" are set simultaneously, the enable is removed and the motor stops without a deceleration ramp (block voltage).

4.3.4.4 Addressing

In order to use the device in an AS-i network, it must have a unique address. The address is set to 0 in the factory. This means that the device can be recognised as a "new device" by an AS-i master (prerequisite for automatic address assignment by the master).

Course of action

• Ensure power supply of the AS interface via the yellow AS interface cable.

• Disconnect the AS interface master during addressing

• Set the address ≠ 0

• Do not doubly assign addresses

In many other cases, addressing is carried out using a normal addressing device for AS interface slaves (example follows).

• Pepperl+Fuchs, VBP-HH1-V3.0-V1 (separate M12 connection for external power supply)

• IFM, AC1154 (battery operated addressing device)

4.4 PROFIBUS DP

This section is only relevant for device of type SK 175E-...-PBR.

4.4.1 The bus system

PLC's, PC's, operating devices and monitoring devices can all communicate via a uniform bus in serial bit mode using PROFIBUS DP. PROFIBUS DP is preferably used where time-critical rapid and complex communication between individual devices is required. The bus system is suitable as a substitute for cost-intensive parallel 24 V DC signal transfer of process data.

PROFIBUS communication is specified in the international standards IEC 61158 and IEC 61784. Application and planning aspects are specified and documented in the guidelines of the PROFIBUS users´ organisation (PNO). This ensures that devices from different manufacturers can communicate with each other. The data exchange is specified in DIN 19245 parts 1 and 2 and application-specific extensions in part 3 of this standard. As part of the European field bus standardisation process, PROFIBUS is being integrated into the European field bus standard EN 50170.

4.4.2 Features

• Electrically isolated bus interface

• Status display (1 LED)

• Address setting via two rotary coding switches (beneath the casing cover)

• The PROFIBUS termination resistor can be switched in via jumpers

• Transfer of 4 control bits and 4 status bits

• Supports Sync Mode and Freeze Mode of the PROFIBUS DP communication function

• Watchdog function, in case of malfunction all bits of the setpoint PDO are set to 0

• No parameter communication

4.4.3.3 Configuration

Process data

The process data is used to control the motor starter and communicate its status. The transfer of this data is carried out cyclically. There is only one process data object (PDO) for the motor starter, with a fixed data length of 1 byte. Only the bottom 4 bits are used. A distinction is made between the setpoint PDO (from PLC to device (BUS-IN bits)) and the actual value PDO (from device to PLC (BUS-OUT bit)).

The PROFIBUS address of the motor starter can be set within a range of 1 to 79 and 81 to 99 with the rotary coding switches.

If addresses 0 or 80 are set, the motor starter interprets these values as an address of 126. Communication is not possible in this case.

The address is read in directly after switching on the 24 V supply of the motor starter.

An address change only comes into affect on the voltage supply of the device after switching the 24 V DC on again!

5 Parameter

WARNING

Parameter changes become effective immediately. Dangerous situations can occur under certain conditions,

even when the drive is stationary. Functions such as P428 "Automatic Start" or P420 "Digital inputs" or the "Release Brake" setting can put the drive in motion and put persons at risk due to moving parts.

Therefore:

• Changes to parameter settings must only be made when the frequency inverter is not enabled.

• During parametrisation work precautions must be taken to prevent unwanted drive movements (e.g. lifting

gear plunging down). The danger area of the system must not be entered.

The relevant parameters for the device are described in the following. The parameters are accessed using a parametrisation tool (e.g. NORDCON software or control and parametrisation unit, see also ( Section 3.1 "Control and parametrisation options ") and therefore makes it possible to adapt the device to the drive task in the best possible way. Different device configurations can result in dependencies for the relevant parameters.

The parameters can only be accessed if the control unit of the device is active.

The device must be provided with a 24 V DC control voltage to do this ( Section 2.3.3 "Electrical connection of the control unit").

Unexpected movement due to parameter changes

Connections and possible priority switching with the potentiometers (P1…) and the DIP switch (S1) are described in a suitable location and must be taken into consideration (pay attention to P130).

Parameter changes only have a direct influence on the RAM memory of the device and are therefore volatile. In order to retain these changes, a copy job (P550) must be triggered after completing the parameter changes. This causes the data to be transferred to the permanent memory (Flash memory) of the device.

The individual parameters are functionally combined in groups. The first digit of the parameter number indicates the assignment to a menu group:

Menu group No. Master function

Basic parameters (P1--) Basic device settings such as behaviour when switching on/off

voltage))

Additional parameters (P5--) Priority monitoring function and other parameters

The factory settings of the entire parameter set can be loaded at any time using parameter P523. For example, this can be useful during commissioning if it is not known which device parameters have been changed earlier, and could have an unexpected influence on the operating behaviour of the drive.

Restoring the factory settings (P523) affects all parameters. This means that all motor data must subsequently be checked or reset.

The potentiometers (P1-P4) and DIP switches (S1) are also reactivated.

6 Operating status messages

The device and technology units generate appropriate messages if they deviate from their normal operating status. There is a differentiation between warning and error messages. If the device is in the status "Start disabled", the reason for this can also be displayed.

The messages generated for the device are displayed in the corresponding array of parameter (P700). The display of the messages for technology units is described in the respective additional instructions and data sheets for the modules concerned.

Start disabled, “Not Ready”  (P700 [-03])

If the device is in the status "Not Ready" or "Start Disabled", the reason for this is indicated in the third array element of parameter (P700).

Display is only possible with the NORD CON software or the ParameterBox.

Warning messages  (P700 [-02])

Warning messages are generated as soon as a defined limit is reached. However this does not cause the frequency inverter to switch off. These messages can be displayed via the array-element [-02] in parameter (P700) until either the reason for the warning is no longer present or the frequency inverter has gone into a fault state with an error message.

Error messages  (P700 [-01])

Errors cause the device to switch off, in order to prevent a device fault.

The following options are available to reset a fault (acknowledge):

• Switching the mains off and on again,

• By an appropriately programmed digital input (P420),

• By switching off the “enable” on the device (if no digital input is programmed for

acknowledgement),

• By Bus acknowledgement

6.1 Display of messages

LED displays

The status of the FI is indicted by integrated status LEDs, which are visible from the outside in the state as delivered. According to the type of FI, this is a two-colour LED (DS = DeviceState) or two single-colour LEDs (DS DeviceState and DE = DeviceError).

Meaning: Green indicates readiness and the present of mains voltage. In operation, the

level of overload at the FI output is shown with an increasingly rapid flashing code.

Red Signals the presence of an error by fl

code of the error. This flashing code (e.g.: E003 = 3x flashing) indicates the error groups.

SimpleBox - display

The SimpleBox displays an error with its number and the prefix "E". In addition, the current fault can be displayed in array element [-01] of parameter (P700). The last error messages are stored in
