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 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:
Designation Connection Connector PWR
Pin Colour
AS interface PWR
AS interface AUX
AS-i (+) 1 brown - -
AS-i (-) 3 blue - -
AUX 24V 4 black 1 brown
AUX GND 2 white 3 blue
Connector AUX
Pin Colour
In both connectors pin 5 is not used. Pins 2 and 4 of the AUX connector are also not used.
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.

The AS interface network can be set up in any desired form. Linear, star, ring and tree structures are possible. An existing network can be expanded by further slaves at any time. For the sake of simplicity the standard slave application will mainly be described in this manual. Up to 31 standard slaves (i.e. a maximum of 124 binary sensors and 124 binary actuators) or 62 A/B slaves (i.e. a maximum of 248 binary sensors and 248 binary actuators) can be connected to an AS interface network or an AS interface master. Each AS interface slave has its own address (1 to 31 (or 1A … 31A, 1B … 31B)), which is assigned to the slave with the aid of an addressing device, or is transferred to the slave by means of a command from the AS interface master (see the manual of the AS interface master used). Each slave address may only be assigned once.
Normally the AS interface master is a component or module of the control unit and forms the interface between the control unit and the connected slave. An AS-i master communicates independently and exchanges data with the connected AS-i slave options. Normal power units must not be used in the AS interface network. For each AS interface connector, only a special AS interface power units (PELV) may be used for the power supply. This special power supply device for the AS interface must be used in order to decouple the data in the yellow cable. This AS interface power supply is directly connected to the yellow standard cable (ASI+ and ASI­cable) and should be positioned as close as possible to the AS-i master in order to keep the voltage drop small. In order to provide an adequate power supply to the NORD-AS interface modules or sensors and actuators, an additional 24V auxiliary voltage (black cable) must be fed to each slave.

Page 26
NORDAC AS-Interface Manual
The AS interface system replaces the expensive parallel wiring of decentralised sensors (inputs) and actuators (outputs) with a few bits (1-4 bits).
The AS interface options from Getriebebau NORD, which need to be supplied with an additional +24V DC supply (AUX, black cable connection) for the electrical components, can also be used as I/O expansions for customer-specific applications. An AS interface option can be used wherever more I/Os are required than are available on the frequency inverters (i.e. onboard) or on the additional customer's interfaces. The black and yellow AS-i standard cables are completely independent of each other, i.e. if the +24V DC voltage (AUX / black cable) is switched off, the AS interface network (yellow cable) remains in operation and therefore supplies the slave. Due to their special geometrically asymmetrical dimensions, both the yellow standard cable and the optional black AS interface cable are mechanically protected against incorrect polarity.
The AS interface is a "single master / multiple slave system", i.e. there is only one master and several slaves in an AS interface network. In the normal address mode, a maximum of 31 slaves can be integrated and operated in an AS interface network with one master. With AS-i masters which support the extended address mode, up to 62 slaves can be administered by a single master. Both the master and the slaves are connected via the yellow standard AS interface cable. Both the master and the slaves are connected via the yellow standard AS interface cable.
The AS interface master sends the same number of telegrams as the number of connected and active AS interface slaves in the network. Each slave in sequence is cyclically addressed by these telegrams, starting from the active slave with the lowest address.

Slave answers
For the master there are as many slave (addresses), as there are AS interface modules connected to the network and activated. The response time of all active slaves is the data cycle time (approx. 5 ms for max. 31 slaves in standard mode). The response time is fixed or specified (real-time capability) and is proportional to the number of activated slaves. Hence, e.g. the response time is halved for about half the number of slaves to:
5 ms * 15/31 = approx. 2.4 ms.
An AS interface master communicates independently with the AS interface slave modules which are connected and addressed to the AS-i bus. It exchanges data with the individual slave modules. A master coordinates all activities on the AS-i bus. An AS-i slave only communicates with the AS-i master on request by the master. The AS-i slave passes on the requested information and signal statuses of the connected peripherals (inputs, outputs...) to the master. A repeated telegram takes 150 µs and is included in the cycle time of max. 5 ms (AS Interface network with S-7.4 slaves) or max. 21 ms (AS Interface network with S-7.A slaves).
It is the task of the control unit (SPS, PC) and not that of the AS-i master to control the plant. However, at the latest after 5ms or 21 ms (the maximum cycle time) the master detects whether a slave is no longer responding (slave failure). The AS interface telegram is the message between the master and the slave in both directions. First the initial data are sent (written) to the connected slave from the master, then the initial data from the slave for each slave access and within a telegram are returned to the master (read).
Data exchange process:
The ASi data protocol provides 4 bits for the exchange of reference data.
During a cycle, each address (1 ... 31) is accessed once by the master. The master sends an order telegram (with 4 Bit reference data) to the slave and immediately receives a corresponding response telegram (also with 4 Bit reference data).
For standard slaves (SK TUx-AS1) the maximum cycle time is therefore 5ms.

p
An additional bit is required in order to address an A/B slave. This bit is inserted into the reference data area, so that the content of the 4 data bits must be divided over 2 protocols, i.e. 2 transmission cycles.
On the other hand, the response telegrams contain all 4 data bits, so that the telegrams from the slave to the master are completely updated after each order.
Also, due to the extended address range, A/B slaves can only be accessed every 2nd cycle. This also additionally doubles the cycle time for these participants.

For the operation and parameterisation of the master please refer to the particular manual of the AS-i master manufacturer. There you can find more detailed information regarding the individual AS interface masters used.
The main component of the AS interface is a special slave module, which can control the following functions:
I. only 4 inputs,
II. only 4 outputs
III. 4 inputs and 4 outputs simultaneously (within a single telegram)
Therefore, according to III, there are a maximum of 248 binary inputs and outputs for an AS interface system with 31 slaves (496 in extended address mode with A/B slaves). This AS interface chip (ASIC) has 4 parameter bits for the non-cyclic setting of special slaves. If the parameter bits are used, the master transmits asynchronous parameter telegrams between the normal data cycles.
NOTE
The address range available is from 0 - 31 (62 for A/B slaves):
For normal addressing of slaves do not use the address 0. Address 0 is an exception and is reserved for automatic addressing via the master.
In general, there are two categories of AS interface slaves:

In the "configuration" status the slave waits to be identified by the master and ultimately to be activated. This is performed by means of a command "Exchange parameters" After this the slave reverts to normal operation and responds to calls for data. A timeout function "watchdog" monitors the current data communication. If this fails for a certain time ("timeout"), then the outputs are reset and the slave reverts to the "configuration" status.

Process interface to the sensor/actuator/field device (only modules)
Interface to the AS interface network.
Device profile:
The device profiles are uniquely labelled by the combination of the I/O configuration, ID code, ID1 code and ID2 code and therefore identify each slave.

NOTE
For the identification of the slave by the master, in addition to the slave address, each certified slave has a fixed, non-volatile ID and I/O code (identification, input/output code) according to the AS interface specification. After switching off, the ID, I/O code and the address are stored "non­volatile" in an internal slave EEPROM. Only the slave address can be changed by the user (via
the master or a manual programming device).
3.1 Laying the bus cables
The length of the AS interface cable must not exceed 100m. For greater distances a repeater should be used. The maximum length can be extended to 300m with two repeaters. Caution: An additional AS-i power unit must be used after each repeater.
By the use of several repeaters in different conductors and a star configuration of the network, a total bus length of 500m may be achieved. For this, the AS-i master must be located in the central segment of the AS-i bus system.
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. These installation instructions can not be complete and do not constitute a release from the applicable safety and accident prevention regulations.
Although the use of shielded cable for AS interface applications is possible, it can however, have a negative effect on the length of the conductors which can be achieved. The AS interface is a potential-free and ground (earth)-symmetrical system, which provides a high resistance to interference in industrial environments, even without additional measures such as shielding.
Non ground (earth)-symmetrical cable configurations over long distances are unfavourable and must be avoided. In addition, care must be taken that the AS interface cable is laid separately from power cables.
BU 0090 GB 29
Page 30
NORDAC AS-Interface Manual
3.2 Cable type
A simple 2-wire cable with a cross section of 2 x 1.5mm² should be used for networking. It is recommended that the yellow profile cable is used. Due to the mechanical profile of the cable, each slave can be simply connected without danger of incorrect polarity. As the geometrically coded position of the wires is fixed and there is no obstruction from shielding, the slaves can be connected to the AS interface bus using simple insulation piercing components. The twin-wire profile coded flat cable must not be twisted, screened and terminated with a terminal bus resistor. For further information, or which cable type was specified for the AS interface application, please refer to the AS interface specification.
There are different coloured flat cables for different applications:
Yellow for the AS interface Black for the 24V auxiliary power supply
The warranted transfer speeds or transfer distances without disturbances can only be achieved if the specified cable parameters are complied with.
The maximum length of the yellow cable without a repeater is 100m including the spur cables and branches of the free AS interface topology. The maximum length of the black cable depends on the power consumption of the actuators and is normally shorter than the length of the yellow cable. The permissible voltage range direct to the actuators must be checked.
3.3 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. Correct laying of the bus cable dampens the electrical influences which may occur in an industrial environment. Bus lines should be laid with a minimum spacing of 20cm to other lines which carry a voltage higher than 60V. This applies to lines laid inside and outside of control cabinets.
A separate cable should be used for each AS interface conductor, i.e. AS interface cables should not be laid with other AS interface conductors or other power circuits in a common cable.
If however, e.g. single wires are used in a switching cabinet, both wires for AS+ and AS- should always be installed in pairs and twisted wherever possible.
NOTE
For applications with frequency inverters AC line input (mains) filters, or if necessary output chokes and shielded motor cables should be used.
When laying the cables, as great a distance as possible should be maintained between potential
sources of interference such as frequency inverters and their cables.

Parameters and settings specific to the AS interface can be made via a ParameterBox or also via the NORD CON software. For more detailed information, please refer to the corresponding operating instructions.
To ensure bus monitoring of the AS interface, the telegram downtime P513 should be parameterised by the
user. This prevents an uncontrolled start-up (with enabling via the bus) of the drive unit after restoration of the bus connection.
4.1 Frequency inverter BUS parameters
In order to operate the frequency inverter with the AS interface, in addition to the bus connection to the master, several parameter settings must be made on the frequency inverter.
Control of the frequency inverter via the AS interface can be activated by setting parameter P509 to a value for control via control terminals (e.g. 0, 1, 2, 5, for further details please see below), as the data from the AS
interface is treated as input and output terminals. These BusIO In or BusIO Out bits should be regarded as extensions to the control terminals. The same functions can be realised as can be parameterised via the digital
inputs or the multifunctional output relay. The functions are specified in P480 or P481. In order to process the AS interface data as control terminals, one of the setpoint values (P546, P547 or P548) must be applied to BusIO In bits. The digital Bus I/O In functions for the inputs (sensors) DI1 to DI4 are allocated in parameter
P480 in the arrays [05] to [08]. For the digital Bus I/O Out functions the allocation of the outputs (actuators) DO1 and DO2 is carried out in parameter P481 in the arrays [05] or [06]. In order to process the AS interface
data as output terminals, one of the setpoint values (P543, P544 or P545) must be parameterised to BusIO
Out bits. Enabling of the bus transfer can be checked by means of the information parameter P740 Control word Bus and P741 Status word Bus . With this, e.g. the process input and output data is displayed during
operation. In addition, module information and status information can be displayed via the parameters P745 and P746. Parameterisation of the frequency inverter via the parameter string transfer (see Section 5.3) can be
carried out without a particular setting.

[01]= Bus I/O Out Bit 0 [02]= Bus I/O Out Bit 1 [03]= Bus I/O Out Bit 2 [04]= Bus I/O Out Bit 3 [05]= Bus I/O Out Bit 4 [06]= Bus I/O Out Bit 5
Standardisation of bus I/O Out bits
Adjustment of the limit values of the relay functions/Bus Out Bits. For a negative value, the output function will be output negative.
When the limit value is reached and the setting values are positive, the relay contact closes, with negative setting values the relay contact opens.
Hysteresis of bus I/O Out bits
Difference between switch-on and switch-off point to prevent oscillation of the output signal.
[07]= Bus I/O In Bit 6 [08]= Bus I/O In Bit 7 [09]= Flag 1 (only SK 500E) [10]= Flag 2 (only SK 500E) [11]= Bit 8 BUS control word (only for SK 500E) [12]= Bit 9 BUS control word (only for SK 500E)
[07]= Bus I/O Out Bit 6 / Flag 1 [08]= Bus I/O Out Bit 7 / Flag 2 [09]= Bit 10 BUS status word (only for SK 500E) [10]= Bit 13 BUS status word (only for SK 500E)
NOTE
For flank-controlled input functions via BusI/O or AS interface In Bits and simultaneous connection of a ParameterBox, the signal flank may be incorrectly identified, i.e. the drive unit may be unintentionally enabled! This behaviour occurs with the combination of different types of
protocols.

Monitoring function of the active bus interface. Following receipt of a valid telegram, the next one must arrive within the set period. Otherwise the inverter reports an error and switches off with the
error message E010 (10.0) >Bus Time Out<. Note: For AS interface applications, the telegram downtime should be parameterised, in
order to prevent uncontrolled starting (with enabling via the bus)of the drive unit after restoration of the bus connection. In addition, the error display is activated by the parameterisation of the telegram down time.
With the setting value 0 or <0.1, an internal timeout time of 40 ms is used, which does not result in an inverter error. With a setting value 0.1 after the elapse of an internal timeout time of 40 ms an error is generated and displayed on the inverter. The internal timeout time of 40 ms is used to indicate errors in the AS interface communication (see Section 4.3)

4 Frequency inverters - settings and control elements
4.5 Peripheral error on AS interface module
A peripheral error of an AS interface slave occurs if:
No AC line input (mains) voltage is applied to the inverter
The 24V supply (AUX 24V) to the AS interface module is not present
A peripheral error is not reported if an error specific to the inverter is present. If a peripheral error is active, the signal statuses of the 4 Out data bits from the AS interface module to the AS interface master are set to LOW. This must be taken into account in programming or processing (pos. logic) the input signals in the control unit.
In order to prevent uncontrolled starting of the drive unit after a communication error, the user should monitor peripheral errors in the control program. As soon as a peripheral error is reported, the enable signal - which is parameterised via the BusIO Bits - should be reset by the application program.
NOTE
A second or better error monitoring facility would be to parameterise the error [7] (see P481) via one of the four available AS interface BusIO Out Bits, and to evaluate or link this accordingly. The error bit is set to "1" in case of no error, and is set to "0" if one of the following error conditions occurs:
¾ Error specific to the frequency inverter
¾ Frequency inverter has no AC line input (mains) voltage
¾ AS interface module not ok (see error status LED indicators Section 4.3).
¾ Either the PWR AS interface power supply or the 24V power supply is missing!
Acknowledgement of the error [12] (see P480) should then be carried out via one of the four available BusIO In Bits.

5 Data transfer / Parameter-string transfer
NOTE
The information in Section 5 does not apply to the AS interface Technology Unit SK TU2-AS3
(A/B slave).
(only necessary for extended functionality)
The Parameter string transfer is available for the modules SK TUx-AS1 (Standard slaves, slave profile S-7.4). This extended functionality is implemented in the AS interface master according to the Complete Specification 2.1. With this, direct communication and transfer of parameter data to the AS interface slave can
be simply realised. In contrast to the data transfer from the sensors (cyclical processing), the string transfer is carried out acyclically. Therefore the transfer of parameter strings takes considerably longer than the cyclical exchange of 4I/4O data.
By means of the functions "write parameter" and "read parameter", parameters in the frequency inverter can
be changed or read out by the application control program. Three string reading commands and a string writing command are available:
Read ID string -Inverter and AS interface version information and identification
Read diagnosis string -Signal statuses of the I/Os, process data and if necessary, inverter error no.
Read parameter string -Read out the parameter values of the frequency inverter
Write parameter string -Write the parameter values of the frequency inverter
The following sections provide information on the available commands.
NOTE
It should be noted that with continuous parameter string transfer and certain interface-bus configurations, the cyclical data exchange (every 5ms) to and from the sensors is suppressed! Due to the specified AS system behaviour, this condition cannot be avoided by NORD as manufacturers of the device. This system behaviour must therefore be taken into consideration when programming the control unit and the use of the parameter string transfer functionality.

5.3 Read / Write parameter string
(read from slave / write to slave)
The parameterisation of the frequency inverter can be carried out and checked with the commands Read parameter string and Write parameter string. Information parameters can also be read out in the same way.
For both reading and writing, the first two bytes in the parameter string are used as an index. Then the data content is transferred. The number of data words is restricted to 8 words (16 Byte). The total string transfer length is therefore limited to a maximum of 9 words (18 Bytes). Transfer is always in the form of complete words, i.e. odd numbers of bytes may not be transferred. There is a facility for simply accessing several parameters (direct parameters), and a more complex access to all parameters via the USS protocol. Both parameterisation facilities are described in the following sections.

5.3.1 Direct parameters
The list of direct parameters contains selected parameters from the entire parameter range of the frequency inverter. With direct parameters, individual or several parameter sets or array elements can be written simultaneously (from 1 to 8 words or values). In order to read a direct parameter, the index of the relevant direct parameter must be sent with a Write order of length 1 word prior to the read command. After this, the index and the associated value (total 2 words) are transferred with a Read command.
Even after a Write order in which one or more values are written, with the next Read command the first value is read back. Here a certain time ( 200ms) must elapse before the value can be checked with a Read command (very important for the transfer of several parameters). After each Read command the index is automatically increased by 1 and the next value can be read without starting a further Write order. After reading the last direct parameter the index is again set to the first direct parameter.

As up to 8 data words (16 Byte) can be transmitted, it is also possible to transfer up to 4 parameter sets from two consecutive parameters by means of a single direct parameter Write command. If e.g. for SK 700E the index 0054
and 8 data words are written, the 4 parameters of the start-up time P102 and the braking time
hex
P103 are each changed. If only two parameter sets are available (SK 300E) the data words for the parameter sets 3 and 4 are not processed, i.e. the two data words are simply placeholders.

There are permissible lengths of a total of 4 and 5 words, corresponding to integer (16 Bit) and long (32 Bit) parameters. Write orders with other lengths are ignored by Index 00 02 00 00
. If a Write order is transferred in order to read a parameter, this must also have the corresponding
hex
. This causes the index to be reset to
hex
length (integer/long). The parameter value for the Read command is only updated once by the frequency inverter, i.e. if at a later time only the Read command is carried out (without a previous Write order), the parameter value read is not the current one. If e.g. an information parameter (P7xx) is to be regularly read, this must always be started with a new Write order and a subsequent Read command.

5.4.2 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) can be transferred:

With the setting 'Actual position' and 'Setpoint position' the actual absolute position is transferred. The
resolution is 1 = 0.001 revolutions. If the value 'Setpoint position 32 Bit' is set in parameter P546 (Function setpoint 1), then the actual value (Setpoint or actual position) is also transferred to IW2 and IW3 as a 32 Bit

5.4.3 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 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). The standardisation corresponds to actual value 1 (see above)
5.4.4 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:

5 Data transfer / Parameter-string transfer
5.5 Data transfer with USS reference data / Parameter range (PKW)
(only necessary for extended functionality)
The reference data (without telegram framework) correspond to the USS protocol.
Using the PKW mechanism, parameter processing can be carried out in the cyclical data traffic. For this the master formulates an order and the inverter formulates the response to this.
In principle, the parameter range consists of a parameter identification, in which the type of order (Write,
Read etc.) and the relevant parameters are specified. Individual parameter sets or array elements can be
addressed with the aid of the Index. The parameter value contains the value to be written or read.
Note: A parameter order must be repeated until the inverter responds with the corresponding response
telegram.
5.5.1 Parameter label (PKE)
The order or response and the associated parameters are encrypted in the parameter label (PKE).

Note: For the inverter parameter numbers (PNU) please refer to the relevant operating instructions

The following table lists all the orders which can be transferred from the master to the inverter. The right-hand column contains the response, which is normally sent (response label positive). Only certain response labels are possible, depending on the order label. In case of error (response label negative) the inverter will always supply the value 7 in the response label (AK) to the master.

As long as an order has not yet been executed, the inverter provides the response to the last order. Therefore the master must always check whether the received response matches the order sent. For the plausibility check, the value in the response label (AK), the received parameter number (PNU) with the corresponding Index (IND) as well as the current parameter value (PWE) can be used for the description of parameters.

Sub-index
Array 1-256
The structure and function of the parameter index (IND) depends on the type of parameter to be transferred.
For values which depend on the parameter set, the parameter set can be selected via Bits 8 and 9 of the Index (IND) (0 = parameter set 1, 1 = parameter set 2,...).
If the parameter to be processed is also an array parameter (e.g. position array for the PosiCon option), then the sub-index of the required parameter can additionally be accessed via Bit 10 to Bit 15 of the sub-index (0 = array element 1, 1 = array element 2,…):
Array element Parameter set Index

) 4 (11
BIN
If a parameter is not dependent on the parameter set, then Bit 8 -15 are used for the sub-index.
Please refer to the operating instructions for details of the structure of the individual parameters and which values may be called up.
If the sub-index is used, nos. 6, 7, 8 or 11, 12 must be used as the order label (see Section 5.5.1), in order for the sub-index to be effective.

5.5.3 Parameter value (PWE)
For each parameter, the transfer of the parameter value (PWE) is always as a word (16 Bit) or double word (32 Bit). Only one parameter value can be transferred in a telegram.
A 32 bit parameter value comprises PWE1 (high value word) and PWE2 (low value word, 4th word).
A 16 Bit parameter value is transferred in PWE2. For negative values the high word must be set to FFFF
Note: 32- Bit parameter values are only used with the posicon option. All the relevant parameters are
described in the supplementary posicon manual.
The parameter value is transferred as an integer value. For parameters with resolutions 0.1 or 0.01 the parameter value must be multiplied by the inverse of the resolution.
Example
99.99s → 99.99 * 1/0,01 = 99,99 * 100 = 9999. Therefore the value 9999

6.1 Example based on a Siemens Master CP343-2P
This example supports the user in the design and implementation of the AS interface application. Information is presented for various application examples, which illustrate which steps are necessary in order to control the frequency inverter with the SPS via the AS interface. This example is illustrated for a SIMATIC S7-300 automation device. Prerequisites for the understanding of this document are:
Basic knowledge of the SIEMENS SIMATIC S7, STEP 7
Knowledge of the operation of frequency inverters – BU 0300, BU 0500, BU 0700, BU 0750
Knowledge of the manual CP 343-2 / CP 343-2 P for the AS interface master
For the procedure regarding the design of the AS interface master in STEP 7 please refer to the Siemens manual. All examples described here refer to an AS interface slave with address 1 for the SK 700E series.
6.1.1 Slave design
In order to connect the AS interface slave to the AS interface bus, or to activate it on the AS interface master,
the CP343-2 P must be switched to design mode. By means of key "Design" (see Siemens AS interface master manual) the device can be switched over from protected mode to design mode.
In addition to key "Design" (to record the actual current configuration) a setpoint configuration can be designed and loaded into the CP via the hardware configuration in Step 7.
6.1.2 AS interface control Bits (control signals)
The relevant digital inputs and outputs (4I/4O) are accessed via Step 7 peripheral loading and transfer commands (see program example FC1). For each standard slave 4 input Bits are read in or 4 output Bits are available.
As an example, the following illustrates the allocation of the input and output Bits for Slave 1:
Input Byte 1 Reserved Slave 1
Bit No. 7 6 5 4 3 2 1 0
Bus module connection
Output Byte 1 Reserved Slave 1
Bit No. 7 6 5 4 3 2 1 0
Bus module connection
For more precise I/O Byte allocation for all standard slaves, please refer to the AS interface master manual. The numbering of the In and Out Bits in the AS interface master manual may differ by "1".
By means of the digital 4I/4O data Bits, the control of the frequency inverter can be operated or the control unit can receive status information from the frequency inverter.
For example, a frequency inverter is to be enabled for the directions of rotation right and left via the digital AS interface In Bits. In addition, a parameter set switchover and an error acknowledgement are to be parameterised via the In Bits. The operation and the error indication of the frequency inverter are to be transferred to the control unit via the first two of the four digital AS interface Out Bits.

For this, the following FI parameters must be set as follows:
P480 [01] Bus IO In Bit 0 1 = Enable right
P480 [02] Bus IO In Bit 1 2 = Enable left
P480 [03] Bus IO In Bit 2 8 = Parameter switch-over
P480 [04] Bus IO In Bit 3 12 = Error acknowledgement
P481 [01] Bus IO Out Bit 0 2 = Inverter operating
P481 [02] Bus IO Out Bit 1 7 = Error
P509 interface 0 = Control terminals or keyboard control
P543 Bus actual value 1 12 = Bus IO Out Bits 0-7
P546 Bus setpoint 1 17 = Bus IO In Bits 0-7
For the switch-over of the parameter set it should be noted that the parameters dependent on the parameter set, e.g. P543 and P546 are also accordingly parameterised onto Bus IO Bits.
6.1.3 AS interface binary values (Digital inputs and outputs)
The following example purely serves for the I/O expansion of the control signals and can also be operated without the AS interface master.
For example, a frequency inverter is to be enabled for the directions of rotation right and left via the digital AS interface In Bits (Sensor Dig), and the direction of rotation changed via the second sensor input. In addition, a setpoint increase is to be made via fixed frequency 1. An error acknowledgement is to be performed with the fourth and last In Bit (Sensor Dig). The operation and the error indication of the frequency inverter are to be output via the first two of the four digital AS interface Out Bits (Actuator Dig).
For this, the following FI parameters must be set as follows:
P429 Fixed frequency 1 e.g. 10 Hz
P480 [05] Bus IO In Bit 4 (Sensor Dig In 1) 1 = Enable right
P480 [06] Bus IO In Bit 5 (Sensor Dig In 2) 3 = Reverse direction of rotation
P480 [07] Bus IO In Bit 6 (Sensor Dig In 3) 4 = Fixed frequency 1
P480 [08] Bus IO In Bit 7 (Sensor Dig In 4) 12 = Error acknowledgement
P481 [05] Bus IO Out Bit 4 (Actuator Dig Out 1) 2 = Inverter operating
P481 [06] Bus IO Out Bit 5 (Actuator Dig Out 2) 7 = Error
P509 interface 0 = Control terminals or keyboard control
P543 Bus actual value 1 12 = Bus IO Out Bits 0-7
P546 Bus setpoint 1 17 = Bus IO In Bits 0-7

6.1.4 Data transfer of the sensor signal statuses to the AS-I master alone
It is often the case that the signal statuses from photoelectric beam detectors, buttons or other field components have to be communicated to the AS i master via the two-conductor AS interface network. In the parameterisation of the available BUS IO bits, there is the possibility of transferring the signal statuses of sensors connected to the AS interface module or the IO sockets 1/2 to the ASi master. In this case the sensor inputs (Bus IO In Bits) are not assigned with any inverter-specific functions and are assigned to the ASi master or control unit for processing. The parameters described in Section 4.1 are available for the pure processing of the sensor signal statuses.
The following example serves purely for the recording of the signal statuses of the sensors/initiators via the AS
interface. Transfer is only possible if the frequency inverter is switched on (AUX and PWR connection and supply to the AS interface module is not sufficient).
For example, the four digital AS interface n Bits (Sensor Dig) are to be recorded via the frequency inverter or the AS interface module. For this, the following FI parameters must be set as follows:
P480 [05] Bus IO In Bit 4 (Sensor Dig In 1) 0 = No function
P480 [06] Bus IO In Bit 5 (Sensor Dig In 2) 0 = No function
P480 [07] Bus IO In Bit 6 (Sensor Dig In 3) 0 = No function
P480 [08] Bus IO In Bit 7 (Sensor Dig In 4) 0 = No function
P481 [01] Bus IO Out Bit 4 (AS-Interface Out Bit 1) 34 = Bus IO In Bit 4
P481 [02] Bus IO Out Bit 5 (AS-Interface Out Bit 2) 35 = Bus IO In Bit 5
P481 [03] Bus IO Out Bit 6 (AS-Interface Out Bit 3) 36 = Bus IO In Bit 6
P481 [04] Bus IO Out Bit 7 (AS-Interface Out Bit 4) 37 = Bus IO In Bit 7
P509 interface 0 = Control terminals or keyboard
P543 Bus actual value 16
P546 Bus setpoint 17
12 = Bus IO Out Bits 0-7
17 = Bus IO Bits 0-7
6.2 Example of data transfer / Parameter-string transfer
(extended functionality / does not apply to A/B slaves)
For extended functionality the commands described in Section 5 are available. If the commands or orders are not completed with DONE = 1 - order completed without error, but rather ERROR = 1, order completed with error, a corresponding error code is indicated in the AS interface status word. The precise description of errors is documented in the Siemens AS interface master manual. In addition to the 4 commands described (see Section 5) further commands (see Siemens AS interface master manual) can be used.
For the extended operation of the CP 343-2 P the STEP 7 module FC "ASI-3422" (Version 2.0) should be used. In the program example, DB13 is declared as the command interface.

One of the three actual Bus values in parameters P543 to P545 must be parameterised on Bus IO Out Bits 0…7.

One of the three Bus setpoint values in parameters P546 to P548 must be parameterised on Bus IO Out Bits 0…7.

The index (see Section 5.3) must always be entered as words in the first two bytes DB13.DBB7 and DB13.DBB8. After the command or the order from the AS interface has been completed without error (DONE = 1), the transferred functions or parameters are communicated to the frequency inverter. For the available functions, please refer to the information in Section 5.3.
Note: The byte numbers in the following tables refer to the byte designations in Section

Example of writing of direct parameters:
Direct parameterisation is available in order to quickly re-parameterise selected parameters on the frequency inverter (See Section 5.3.1). E.g. in order to change the start-up time P102 in parameter set 1 to 10.00s, proceed as follows:

If subsequently, i.e. without a further Write order being started in the meantime, one or more Read orders are started consecutively, the AS interface reads the corresponding parameter values consecutively according to the Index sequence of the direct parameter table. The AS interface automatically counts up the index.
Note: This automatic Index increase only applies to the direct parameter function.
As a result, after the next Read Parameter String order, the parameter value P102, start-up time, is read out from parameter set 2 in the reception buffer.

6.4 AS interface as I/O expansion of the frequency inverter control terminals
By means of the AS interface module the number of digital inputs and outputs on the frequency inverters or made available by the use of a customer interface can be expanded by 4 further inputs and two outputs.
Via the 4 sensor inputs (Sensor Dig In / Bus IO In Bits 4 to 7) all functionalities specific to the frequency inverter can be assigned or parameterised via the parameter arrays in parameter P480. The possible settings are described in Section 4.1.
The following example serves purely for the expansion of the input and output range of the frequency inverter without field bus connection. The connection of the yellow AS interface cable (PWR) is not necessary for this application, however, a 24V power supply (AUX) to the module is essential. In addition to the possibility of connection via the digital inputs on the control connections, via the 4 AS interface module sensor inputs, additional functionalities for a Posicon application and the use of an SK 530E are illustrated. For this, the following FI parameters must be set as follows:
Function requirement for SK 530E with SK TU3-AS1 option:
Manual, semi-automatic and automatic operation, i.e. parameter switch-over
PS 1 manual operation. PS2 semi-automatic, PS3 automatic ("PS" = Parameter set)

7 Faults
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".

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.
