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!

1.1 General information

This DeviceNet 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

As well as the communication profile, DeviceNet defines so-called device profiles for the most important types of device used in industrial automation technology, e.g. digital and analog I/Os, drives, etc.

DeviceNet is an open field bus system, via which various control units such as SPS or PCs can be linked to sensors and actuators.

Devices from various manufacturers and with different degrees of complexity can be linked with DeviceNet and can be controlled, diagnosed, configures and parameterised via the bus.

DeviceNet provides the connection between the communication participants via the proven "Common Industrial Protocol" (CIP). The physical basis for this is the CANbus.

1.3 DeviceNet with NORDAC frequency inverters

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).

2.1.1 DeviceNet module SK TU3-DEV

This DeviceNet module can be used for all types of SK 500E devices. It occupies the technology slot which can then no longer be used for control and display modules. Alternatively, the SimpleBox SK CSX-0 can be plugged on to the DeviceNet module and connected via the RS232/485 interface with the frequency inverter.

The DeviceNet module must be provided with an external 24V power supply therefore be identified by the master system even without a voltage supply to the frequency inverter. The data required for this purpose are set using a rotary coding switch. This Bus data is read in when the 24V is applied from the frequency inverter.

Supply voltage:

The supply voltage is 24V DC ±25% (pin 1 = V-, pin 5 = V+ (from left to right)). The connection is made via the 5-pin open-style plug connector. (See illustration below)

Setting the node address: (See Section.

5.4) The node address (0...63) can be set with the rotary switches NA x 1 and NA x 10: Example: Node address = 50 dec = NAx 1 = 0, NAx 10 = 5 If the node address is set to a value greater than 63, the value from the parameter (P515[-01]) of the frequency

inverter is used as the node address.

Setting the baud rate: (See Section

5.4)

The baud rate can be set using the rotary switch DR (125kBit/s...500kBit/s). If a value in the PGM range is set, the value from parameter (P514) of the frequency inverter is used as the baud rate.

Note: The settings made using the rotary coding switch are not transferred to the frequency inverter or saved.

2.2 NORDAC SK 700E

With the combination of modules for display, technology units and modules with digital and analog inputs and interfaces, customer interfaces or special extensions, the NORDAC SK 700E can easily be extended tot cater for the requirements of a wide range of different applications.

WARNING

Technology units (TU) are modules which can be inserted from

above for display, parameterisation and control of the inverter.

Customer interfaces (Customer Units) are modules which are inserted into the upper slot inside the inverter. They are used fo control and communication using digital/analog signals or bus interfaces.

Special extensions (EXtension Units) are inserted into the lower slot of the inverter. Such an extension unit is required if the speed is to be controlled or positioned by an incremental (absolute) encoder.

Modules must not be inserted or removed unless the device is free of voltage. The slots may

only be used for the intended modules. The slots are coded to prevent them being mixed up.

Installation of a technology unit separate from the frequency inverter is not possible. It must be

connected directly to the frequency inverter.

Participants

Communication, connection objects

Predefined Master/ Slave Connection Set

Object model

Explicit Message

I/O Messages

Polling

Bit-Strobe

Up to 64 participants can communicate wi th each o ther in a DeviceNe t network. Eac h participant has its own node address.

Communication between the individual devices is carried out via connection objects. Before the exchange of data can start, these connections (Connection Objects) must be set up.

The Predefined Master/ Slave Connection Set provides an interface with which a set of up to 4 connections can be allocated:

Explicit Messaging Connection Polled I/O Connection Bit.Strobe I/O Connection Change Of State / Cyclic I/O Connection

Access to the slave is only possible from a Master. DeviceNet describes all data and functions on the basis of an object model. An object

represents the individual components within a device. It is determined by its data or characteristics (attributes) and provides functions or

services (Services) for external access. An object class defines all characteristics (attributes/services) for objects of the same type. With the creation of an object instance, a real copy of the object with its own data is created.

Via Explicit Messages , low priority configuration or diagnostic data are exchanged (parameterisation). This connection is always a point-to-point connection according to the Client/Server principle.

I/O Messages are used to transfer process data. An I/O Message always has a producer (transmitter). However, several consumers (recipients) may exist. The process data can contain either 8 Bytes (unfragmented) or can be distributed (fragmented) over several telegrams.

A Polled connection corresponds to a Master-Slave connection: The Master send cyclical data to the Slave. This then responds with its status data.

In aBit-Strobe connection, the Master sends an 8 Byte telegram to all connected devices. Each participant is allocated exactly one bit. As all participants receive the telegram simultaneously, a synchronous reaction can therefore be carried out. The reaction of the individual participants is specific to the application and must be known to the Master. Bit-Strobe telegrams are not confirmed.

4 Bus structure

4 Bus configuration

A DeviceNet network consists of a maximum of 64 participants (nodes) and is based on a linear topology. The number of participants is dependent on the driver modules (standard approx. 100 nodes). Repeaters must be used for a high number of nodes.

Shielded, 5-wire cables according to the DeviceNet specification must be used.

4.1 Laying the bus cables

In an industrial environment the correct installation of the bus system is particularly important in order to reduce potential interference. The following points are designed to help prevent interference and problems right from the start. The installation guidelines are not complete and applicable safety and accident prevention guidelines must be complied with.

4.2 Cable length

The guaranteed transfer speeds or transfer distances can only be achieved without errors if the specific cable parameters are complied with.

2-wire shielded copper cable should be used.

Bus length Maximum baud rate

up to 500m 125 KBit/s up to 250m 250 KBit/s up to 100m 500 KBit/s

The maximum length of spur cables depends on the cable material and the selected baud rate. These can be seen in the DeviceNet specification.

4.3 Cable layout and shielding (EMC measures)

Without EMC measures, high frequency interference, which is mainly caused by switching processes or lightning often has the effect of interfering with electronic components in the bus participants and error-free operation is no longer ensured.

Appropriate shielding of the bus cable reduces electrical interference which can arise in an industrial environment.

Bus lines should be laid with a minimum spacing of 20 cm to other lines which carry a voltage higher than 60 V. This applies to lines laid inside and outside of control cabinets.

Note: If earthing potential values are different, transient current may flow through shielding which is

connected on both sides. This may be a danger to electronic components. Differences in potential must be reduced using sufficient potential equalisation.

With the NORDAC SK 500E and SK 700E series, the PE terminal of the module must be connected to the PE of the frequency inverter (e.g. shielding angle)

NORDAC DeviceNet Manual

5 Frequency inverters - settings and control elements

5.1 Frequency inverter bus parameters

To operate the inverter with the DeviceNet protocol, the bus must be connected to the Master and some settings must be made on the frequency inverter.

With the DeviceNet protocol, the inverter parameters are mapped onto DeviceNet objects in the range 100 to 109:

- Class = 100 + parameter number / 100

- attribute = parameter number % 100

- instance = sub-index +1

- Parameter number = (class – 100) * 100 + attribute

- sub-index = instance -1

The frequency inverter can always be parameterised. Control of the inverter via DeviceNet can be activated by setting parameter P509 to value 18, 19 or 20 (SK 500E: value 7). (see below)

6.4 Process data (PZD)

In the process data area (PZD) , control words and setpoints are transferred from the Master to the Slave (frequency inverter) and in return, status words and actual values are sent from the Slave to the Master. The structure of the PZD area is always the same in terms of the sequence of its elements (words), however, dependent upon direction of data Master ⇒ Slave / Slave ⇒ Master, it is described differently.

The process data area of the reference data has the following structure:

- STW: Con trol Wor d; length 16 bit, order telegram contains control bits (e.g. enable, rapid stop, error acknowledgement)

- ZSW: Status Word; length 16 bit, response telegram contains status bits (e.g. FI running, faul t)

- SW1..3: Setpoints; maximum 3 possible, 16 or 32 bit, order telegram e.g. frequency setpoint, position setpoint, torque setpoint

- IW1..3: Actual Values; maximum 3 possible, 16 or 32 bit, response telegram e.g. actual frequency value, actual position value, actual torque value

6.4.5.2 Setpoint position (16 or 32 Bit)

With the special extension Posicon (SK XU1-POS) of the SK 700E the absolute setpoint position can be transferred as a 16 or 32 Bit value in Setpoint 1, whereby the resolution is 1=0.001 rotation. In addition, the control terminals (setting of Posicon control bits) can be transferred in binary.

The SK 53xE version of the SK 500E series is also able to transfer positions, however here, the 32 Bit position is divided into two 16 Bit components (Low word and High word). The assignment of the two 16 Bit components is then carried out via appropriate parameterisation on 2 arbitrary setpoints (e.g.: SW1 and SW2).

16-Bit setpoint position setting:

As a 16 Bit value, a range of +32767 (= 32,767 revolutions) to -32768 (= -32,768 revolutions) is possible. The 16 Bit setpoint position is transferred as the second word in the process data area (as with the setpoint frequency)

32-Bit setpoint position setting:

As a 32 Bit value, the full position range of +/- 50000,000 revolutions is available. With the SK 700E/750E, the 32 Bit setpoint position is transferred in the area of the process data as the second and third word (with the SK 500E in any two of the three words PZD2, PZD3, PZD4). With SK 52xE:

6.4.6 Second and third setpoint (SW2/3)

With the SK 500E, the assignment of setpoints 2 and 3 to the process data words PZD3 and PZD4 is carried out in the opposite manner to the SK 300E/700E/750E series.

6.4.6.1 Second and third setpoint SK 300E/SK 700E/SK 750E(SW2/3)

If the PPO type 2 or 4 is used, in addition to setpoint 1, a 2nd setpoint can be transferred in word PZD4 and a 3rd setpoint in PZD3.

PZD1 PZD2 PZD3 PZD4

STW

A third setpoint value can only be transferred if a 32 Bit setpoint value is not transferred in the first setpoint.

PZD1 PZD2 PZD3 PZD4

STW

The second and third setpoints are always 16 Bit. The function of the second and third setpoints can be set in the inverter with parameter P547 ‘'Setpoint function 2’ and P548 ‘'Setpoint function 3’ respectively.

Both setpoints are transferred as whole numbers in the range (-32768 to 32767). The value 16384 (4000 HEX) corresponds to 100%. The value C000 HEX is equal to –100%, so setpoints in the range –200% to +200% can be transferred. A setpoint of 100% corresponds to the respective nominal value:

Setting 100% is equal to

Off Setpoint frequency, actual frequency PID, actual

frequency PID limited, actual frequency PID monitored, frequency addition, frequency subtraction, maximum frequency

Torque current limit Torque current limit (P112) Current limit Inverter nominal current Servo mode torque Nominal torque (P112) Lead torque Lead torque (P214)

The second and third setpoints are always 16 Bit. The function of the second and third setpoints can be set in the inverter with parameter P547 ‘Setpoint 2 function’ and P548 ‘Setpoint 3 function’ respectively.

Both setpoints are transferred as whole numbers in the range -32768 to 32767. The value 16384 (4000 HEX) corresponds to 100%. The value C000 HEX is equal to –100%, so setpoints in the range –200% to +200% can be transferred. A setpoint of 100% corresponds to the respective nominal value:

6.4.7 The actual value 1 (IW1)

The actual value 1, i.e. the actual output frequency of the inverter, is transferred as a 16 Bit value as standard in the actual value 1. The actual value 1 is transferred to the master in the inverter response telegram as the second word in the process data area.

The actual value 1 is transferred as a whole number in the range (-32768 to 32767). In addition to the actual frequency, other actual inverter values can be transferred. The setting is made in P543 'Actual value 1 function'.

The settings ‘Actual frequency’, ‘Actual speed’, ‘Current’ and ‘Torque current’ are transferred as percentages of the respective nominal values. The value 16384 (4000 HEX) corresponds to 100%. The value C000 HEX corresponds to -100%. Actual values in the range –200% to +200% can be transferred.

With the setting ‘Digital I/O status’, the states of the control terminals and the relay (MFR) /digital outputs can be transferred:

SK 700E/750E Bit Status

Bits 0-5 Digital input 1-6 Bit 6-11 for posicon special extension unit Digital input 7-12 Bit 6 for encoder special extension unit Digital input 7 Bits 12-15 Multifunctiona l relay 1-4

SK 500E Bit Status

Bits 0-4 Digital input 1-5 Bit 5-6 (above SK 520E) Digital input 6-7 Bits 12-15 Relay and digital outputs 1 - 4

With the setting 'Actual position' and 'Setpoint position' the actual absolute position is transferred. The resolution is 1 = 0.001 revolutions.

If w ith SK 700E/750E the value 'Setpoint position 32 Bit' is set in parameter P546 (Setpoint function 1), then the actual value (setpoint or actual position) is also transferred as a 32 Bit value in PZD2 and PZD3:

6.4.8 Actual value 2 and actual value 3 (IW2/3)

It is possible to forward two more actual values to the controller if PPO type 2 or 4 is used for transfer. The assignment of the actual values 2 and 3 to the process data words PZD3 and PZD4 is carried out in the

same way as the assignment of setpoints 2 and 3. These also differ in sequence between the SK 500E and other inverter series.

6.4.8.1 Second and third actual value SK 300E/SK 700E/SK 750E(SW2/3)

The actual value 2 (IW2) is transmitted in PZD4. The value to be transferred can be selected in P544 (actual bus value 2). Actual value 3 (IW3) can be transmitted in PDZ3 if actual value 1 is not a 32 Bit value. The value to be transferred can be selected in P545 (actual bus value 3).

6.4.8.2 Second and third setpoint SK 500E (SW2/3)

The actual value 2 (IW2) is transmitted in PZD3. The value to be transferred can be selected in P544 (actual bus value 2). The actual value 3 (IW3) is transmitted in PZD4. The value to be transferred can be selected in P545 (actual bus value 3).

6.4.9 The status machine

The frequency inverter passes through a status machine. The changes between various states are triggered by the respective control commands in the process data control word. The actual status is returned in the process data status word.

After switching on, the inverter is in switch-on disabled status. This status can only be ended by transmitting the “Shut down (Off 1)” command.

The answer to a Master telegram normally does not yet contain a reaction to the control command. The controller has to check the answers from the slaves as to whether the control command has been carried out.

The following Bits indicate the status of the frequency inverter:

7 Troubleshooting

7 Errors

7.1 Troubleshooting

The majority of frequency inverter functions and operating data are continuously monitored and simultaneously compared with limiting values. If a deviation is detected, the inverter reacts with a warning or an error message.

Basic information on this topic is contained in the manual for the basic equipment. Errors cause the frequency inverters to switch off, in order to prevent a device fault. The following options are available to reset a fault (acknowledge):

1. switching the mains off and on again,

2. By an appropriately programmed digital input (P420 ... P425 = Function 12),

3. By switching of the “enable” on the frequency inverter (if no acknowledgement),

4. by bus acknowledgement or

5. by P506, the automatic error acknowledgement.

Device LEDs: As delivered, with SK 300E series devices (except ATEX versions) and SK 500E (without

technology unit), 2 LEDs (green/red) are externally visible. 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.

Thered LED signals actual error by flashing with a frequency which corresponds to the

number code of the fault.

The following table shows all the faults which are attributable to bus operation. In the operating display of the optional "ControlBox" only error E010 is displayed. A finer categorisation of errors can be obtained from the information parameters P700 "Actual Faults" or P701 "Last Fault 1...5".

digital input is programmed for

NOTE

For all other series (SK 300E, SK 700E, SK 750E), parameter (P700) still only indicates error messages.

7.1.1 Error display

ControlBox / SimpleBox: The 4-digit, 7-segment display of these boxes indicates a fault with its number and

the prefix "E". If the cause of the error is no longer present, the error display flashes and the error can be acknowledged with the OK key.

ParameterBox: The error messages are shown in plain text.

7.1.2 Error memory

The current error is saved in parameter P700 and the last five error messages are saved in parameter P701 [01]…[-05]. Further information on inverter status at the time the error occurred are stored in parameters P702 to P706 / P799.
