Safety and operating instructions for

drive power converters

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

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, initialisation and maintenance work

must be carried out by qualified personnel (compliant with IEC 364, CENELEC HD 384, DIN VDE 0100, 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 cannot 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 (Machine 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.

The drive power converters 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 according to 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!

SK 180E Manual for frequency inverters

1 General

The SK 1x0E series is based on the tried and tested NORD platform. These devices feature a compact design with optimum control characteristics.

These devices are provided with sensorless vector current control system which in combination with asynchronous three-phase motor types constantly ensures an optimised voltage-to-frequency ratio. This has the following significance for the drive: Peak start-up and overload torques at constant speed.

This series of devices can be adapted to individual requirements by means of extension modules. Due to the numerous setting options, these inverters are capable of controlling all three-phase motors.

The power range is from 0.25 kW to 2.2 kW. The device is equipped with an integrated mains filter. This manual is based on the device software V1.0 R1 (see P707) of the frequeny inverter. If the frequency

inverter used has a different version, this may lead to some differences. If necessary, you can download the current manual from the Internet (www.nord.com).

For the various versions SK 180E / 190E there are also supplementary descriptions for the integrated AS interface (BU 0180, Section 5.4)

If a bus system is used for communication, a corresponding description (e.g. BU 0220 for PROFIBUS DP) is provided, or this can be downloaded from the Internet (www.nord.com).

Typically, this series of devices is installed directly on a three-phase asynchronous motor. Alternatively, optional accessories are available for mounting the devices near to the motor, e.g. on the wall or on a machine frame.

In order to gain access to all parameters, the internal RS232 PC interface (RJ12) can be used, or an optional SimpleBox or ParameterBox may be used. In this case, the parameter settings which are changed by the operator are saved in the EEPROM which is integrated into the frequency inverter.

1.4 Safety and installation information

The frequency inverters are equipment for use in industrial high voltage systems and are operated at voltages that could lead to severe injuries or death if they are touched.

 Installation and other work may only be carried out by qualified electricians and with the

device disconnected. The operating instructions must always be available to these persons and must be strictly observed.

 Local regulations for the installation of electrical equipment and accident prevention

must be complied with.

 The equipment continues to carry hazardous voltages for up to 5 minutes after being

switched off at the mains.

 For single phase operation (115/230 V) the mains impedance must be at least 100 H

for each conductor. If this is not the case, a mains choke must be installed.

 For safe isolation from the mains, all poles of the supply cable to the frequency inverter

must be able to be disconnected.

 Even during motor standstill (e.g. caused by an electronic block, blocked drive or output

terminal short circuit), the line connection terminals, motor terminals and braking resistor terminals may still conduct hazardous voltages. A motor standstill is not identical to electrical isolation from the mains.

 Warning, with certain settings, the frequency inverter/motor can start up automatically

after the mains are switched on.

 The frequency inverter is primarily intended for permanent connection and may not be

operated without effective earthing connections that comply with local regulations for large leakage currents (> 3.5 mA). VDE 0160 stipulates the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm2.

However, connection via a plug connector is also permissible if local regulations are complied with.

 A universal leakage current-sensitive circuit breaker (type B) compliant

with EN 50178/VDE 0160 must be used.

 In normal use, frequency inverters are maintenance-free. The cooling surfaces must be

regularly cleaned with compressed air if the ambient air is dusty.

 The frequency inverters are suitable for operation on TN or TT networks and with

observation of the measures described in Section 2.7.4, they are also suitable for IT networks.

NOTE

The modules for the IP66 design are identified by an additional "-C" and are modified according to the following special measures!

NOTE

For all versions, care must be taken that the cable and the cable gland are carefully matched. Wherever possible, the cables should be inserted so that water is deflected away from the device (if necessary use loops). This is essential to ensure that the required protection class is maintained.

1.7 Version with protection class IP55 / IP66

The frequency inverters and additional modules are available in protection classes IP55 (standard) or IP66 (optional). The protection class IP66 must always be stated when ordering!

There are no restrictions or differences to the scope of functions in either protection class. In order to differentiate the protection classes, modules with protection class IP66 are given an extra “-C” (coated  coated PCBs) in their type designation.

e.g. SK 180E-750-340-B-C

IP55 version: The IP55 version of the external frequency inverter is the standard version. Both versions (motor-mounted,

installed on the motor or wall mounted on the wall bracket) are available. In addition, all adapter units, technology units and customer units are available for this design.

IP66 version: In contrast to the IP55 version the IP66 version is a modified option. Both versions (motor-integrated, close

to motor) are also available. The modules available to the IP66 design (adapter units, technology units and customer units) have the same functionalities as the corresponding IP55 design modules.

The frequency inverters 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.

18 Pre-series version BU 0180 GB-0914

2 Assembly and installation

NOTE

Installation of an IP66-compliant frequency inverter must be carried out by NORD, as special measures have to be implemented. IP66 components retrofitted on site cannot ensure that this protection class is guaranteed.

2.1.1 Mounting the housing box

On delivery of a complete drive unit (gear unit + motor + frequency inverter) the frequency inverter is always fully installed and tested.

When delivered separately, the frequency inverter includes the following components:

 Frequency inverters  Screws and contact washers for mounting the motor terminal box.  Pre-fabricated cable for motor and PTC connections

Procedures:

1. If necessary, remove the original terminal box from the NORD motor, so that only the base of the termi-

nal box and the terminal strip remain.

2. Set the jumpers for the correct motor circuit and connect the pre-fabricated cables for motor and PTC

connections to the respective connection points on the motor.

3. Mount the cast housing on the terminal box base of the NORD motor using the existing screws and seal

as well as the enclosed lock washers. Position the cast housing with the cooling fins towards the fan end of the motor. Check the adaptability for different motor manufacturers.

4. Connect the motor cables U, V, W to the power terminal block and the PTC cable TF+, TF- to the control

terminal block 38, 39.

2 Assembly and installation

CAUTION

The braking resistance and all other metal components can heat up to temperatures above 70°C. When mounting, sufficient distance from neighbouring components must be maintained.

When working on the components, allow sufficient cooling time beforehand

NOTE

The internal brake resistor may only be installed at the factory and can not be retrofitted. It is essential that this is taken into account for the configuration an ordering of the device.

)²)/30(1(* tbrakesPnP 

NOTE

If internal brake resistors are used, a suitable power limit must be set in P555, P556 and P557. This is important in order to activate a peak and continuous power limit for the brake resistor. Otherwise, the brake resistor may be damaged during operation.

2.3 Brake resistor (BR) (only size 2)

During dynamic braking (frequency reduction) of a three phase motor, electrical energy is returned to the frequency inverter. From Size II or larger, an internal or external brake resistor may be used to prevent the FI from shutting down in case of overvoltage. With this, the integrated brake chopper (electronic switch) pulses the link circuit voltage (switching threshold approx. 420V/720V DC, according to the mains voltage) into the braking resistor. The brake resistor ultimately converts the excess energy into heat.

For input voltages >460V the use of a brake resistor is generally recommended in order to compensate for the reduced storage capacity of the link circuit due to the higher voltage.

2.3.1 Internal brake resistor SK BRI4-…

The internal brake resistor can be used if only slight, short braking phases are to be expected.

The output power of the SK BRI4 is limited (see also the following note field) and can be calculated as follows.

, however, P < P

(P=Brake power (W), Pn= Continuous brake power of resistor (W), Pmax. peak brake power, tbrakes = duration of braking process (s))

BU 0180 GB-0914 Pre-series version 25

SK 180E Manual for frequency inverters

The external brake resistor (available for SK 1x0E, Size 2) is intended for energy feedback, e.g. in pulse drives or lifting gear. Here, it may be necessary to plan for the exact brake resistor required.

For installation, an M20 screw connection with an adapter for M25 is supplied. The connecting wires for the brake resistor are fed through this into the connection unit. Because of the cable gland the brake resistor and an optional SK TU4technology unit must not be mounted on the same side of the frequency inverter.

CAUTION!

Modules SK CIF-323-x0 may only be used in combination with a suitable mains choke (L

min

= 3 x 0,73 mH) (see connection diagram).

For SK CIF-340-x0 modules the use of a mains input choke is not mandatory, but is recommended. Note With the use of a mains choke, the effective input currents of the 1~ 230V frequency inverter reduce

to approximately the values of the output currents. Several frequency inverters can be connected to a choke - filter combination. In this case, the total input currents must not exceed the current rating of the filter.

2.4 Overvoltage filter SK CIF

The use of a suitable ("CSA-") overvoltage filter is mandatory (see also Section 1.5) in order to comply with cUL requirements. For 230V devices, operation of the frequency inverter with a suitable overvoltage filter is only permissible if a mains choke is used in addition.

For further information about the overvoltage filter, please refer to the relevant data sheet. These data sheets can be downloaded at www.nord.com.

Without an overvoltage filter, frequency inverters for 1~ 115V mains (SK1x0E-xxx-112-O) cannot be approved according to cUL.

28 Pre-series version BU 0180 GB-0914

2 Assembly and installation

NOTE

The control cables, line cables and motor cables must be laid separately. In no case should they be laid in the same protective pipes/installation ducts.

The test for high voltage insulations must not be used on cables which are connected to the frequency inverter.

ATTENTION

With the use of a ParameterBox SK PAR-3H this must never be simultaneously connected to the frequency inverter and the PC, as potential shifts may cause damage, especially to the PC. (See also Manual BU0040)

2.5 Wiring guidelines

The frequency inverter has been developed for use in an industrial environment. In this environment, high levels of electromagnetic interference can influence the frequency inverter. 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 equipment in the control cabinet or field is securely earthed using short earthing cables

which have large cross-sections and are connected to a common earthing point or earthing rail. It is especially important that all control devices connected to the frequency inverters (e.g. an automation device) are connected to the same earthing point as the inverter itself, using a short cable with large cross-section. Flat conductors (e.g. metal clamps) are preferable, as they have a lower impedance at high frequencies.

(2) The bonding cable of the motor controlled by the frequency inverter should be connected directly to the

earthing terminal of the associated frequency inverter. 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. (see also Section. 9.3 / 9.3.3 (EMC))

(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 analog setpoint cables should only be earthed on one side on the frequency inverter. (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 and brake chokes in the cabinet are interference protected, either by RC

circuits in the case of AC contactors, or by “free-wheeling” diodes for DC contactors, whereby the

interference protectors must be positioned on the contactor coils. Varistors for over-voltage

limitation are also effective. This interference suppression is particularly important when the contactors

are controlled by the relay in the frequency inverter. (6) Use screened or armoured cable for the load connections (motor cable) and earth the

screening/armour at both ends, if possible to the frequency inverter bonding. In addition, an EMC-compliant cabling must be ensured (see also Section. 9.3 / 9.3.3 (EMC)).

The safety regulations must be complied with under all circumstances

when installing the frequency inverter!

BU 0180 GB-0914 Pre-series version 29

SK 180E Manual for frequency inverters

WARNING

THE DEVICES MUST BE EARTHED. Safe operation of the devices requires that is installed and commissioned by qualified personnel

in compliance with the instructions provided in this Manual. 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.

Dangerous voltages can be present at the motor connection terminals even when the inverter is switched off. Always use insulated screwdrivers on these terminal fields!

Ensure that the input voltage source is not live before setting up or changing connections to the unit.

Make sure that the inverter and motor are specified for the correct supply voltage.

2.6 Electrical connection

NOTE: As with other signal cables, thermistor cables must be laid separately from the motor cables.

The housing cover must be removed from the SK 1x0E in order to make the electrical connections. Proceed as follows:

1. Switch off the mains supply and if necessary check and observe the waiting period.

2. Loosen the 4 Allen screws (4 mm).

3. Carefully lift the housing cover vertically from off the housing box.

4. The electrical connections and the option slots are now freely accessible.

30 Pre-series version BU 0180 GB-0914

2.7 Electrical connection of power unit

All connection terminals are located in the connection unit of the frequency inverter.

Separate terminal bars are provided for the power connections and the control connections, as well as a further terminal bar for the connection of the thermistor.

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

Before and while the device is connected, the following must be observed:

1. Ensure that the mains supply provides the correct

voltage and is suitable for the current required (see Section 8 Technical Data).

2. Ensure that suitable circuit breakers with the

specified nominal current range are installed between the voltage source and the inverter.

3. Connect the mains voltage directly to the

terminals L1-L2/N-L3 und PE (according to the device).

4. To connect the motor, three flexible wires U-V-W

should be used when mounting the motor.

5. For wall-mounting a 4-conductor shielded motor

cable (recommended) to the terminals U-V-W and earth should be used. In this case the cable shielding should be connected to a large area of the metallic screw connector.

NOTE: if certain wire end sleeves are used, the maximum cross-section which can be connected may

be reduced.

Screwdriver: Use a 5.5mm slot-head screwdriver to connect the power unit.

NOTE: If synchronous machines or several motors are connected in parallel to a device, the fre-

quency inverter must be switched over to linear voltage/frequency characteristic curves,  P211 = 0 and P212 = 0.

NOTE: Only use copper cables with temperature class 80°C or equivalent for connection. Higher tem-

perature classes are permissible.

NOTE: The use of shielded cables is essential in order to maintain the specified radio interference

suppression level. (See also Section 9.3.3 (EMC))

CAUTION: This device produces high frequency interference, which may make additional suppression

measures necessary in domestic environments. (Details in Section 9.3 / 9.3.3 (EMC))

the braking resistor must be taken into account.

2.7.4 Mains supply jumpers

These jumpers are used to adapt the frequency inverter to various types of networks (e.g. IT network). As delivered, the jumpers are plugged in the "normal position" (CY=ON) and are to be used in a network which is earthed at the star point, with a neutral conductor for single phase devices!

To adapt the frequency inverter to an IT network (only size 2 in combination with a brake resistor), the capacitors Cy must be disconnected from the PE. This is carried out by changing a jumper position as shown in the diagram.

Here it must be noted that the specified degree of radio interference suppression changes. Further details can be found in Section 9.3 EMC.

2.9 Plug connectors

The use of optionally available plug connectors for power and control connections not only makes it possible to replace the drive unit more quickly in case of servicing, but also minimises the danger of installation errors when connecting the device. The most common plug connector versions are summarized below. The possible mounting locations on the housing box are listed in Section 2.1.4.

2.9.1 Plug connectors for power connections

Plug connectors for the motor or mains connection to the frequency inverter are available.

Connection of up to two power plug connectors (HAN Q4-2: up to 2 x 2 plug connectors) are made on the housing of the frequency inverter. The following 3 connection versions are available:

With this, the mains connection and the motor output can be implemented with separate plug connectors in the case of wall-mounted frequency inverters.

For motor-mounted inverters it is possible to install a mains output plug connector instead of the motor connection. Via this, the mains voltage can be looped to the next device.

2 Assembly and installation

ATTENTION

All work must only be carried out with the power to the system switched off. If the frequency inverter is connected to a motor and a gear unit, the EX labelling of the motor

and the gear unit must also be observed.

ATTENTION

Before opening the frequency inverter for the connection of electric cables or other work, the mains voltage must always be switched off and secured against switching on again!

Temperatures may be present within the frequency inverter and the motor, which are higher than the maximum permissible surface temperature of the housing. The frequency inverter may therefore not be opened or removed from the motor in an atmosphere of explosive dust!

Impermissibly heavy dust deposits must not be permitted, as these impair the cooling of the frequency inverter!

All cable glands which are not used, must be closed with blind screw plugs which are approved for explosion hazard areas.

Only the original seals may be used. The protective film covering the diagnostic LEDs in TU4 modules must not be damaged. It must be ensured that the plastic housing cover cannot be electrostatically charged by

streams of particles caused by the fan.

2.10 ATEX Zone 22 for frequency inverters (in preparation)

General information

With appropriate modification, the frequency inverter can be used in explosion hazard areas. For this it is important that all the safety information in the operating instructions is strictly complied with for the prevention of personal injury and material damage. This is essential to prevent injury and damage.

Qualified personnel

Qualified personnel must be used to carry out work involving the transport, assembly, installation, commissioning and maintenance. Qualified personnel are persons who due to their training, experience and instruction, and their knowledge of the relevant standards, accident prevention regulations and operating conditions are authorised to carry out the necessary activities for starting up the frequency inverter. This also includes knowledge of first aid measures and the local emergency services.

Safety information

The increased danger in areas with inflammable dust demands the strict observation of the general safety and commissioning information. The drive unit must comply with the specifications in Planning Guideline No. 6052101. Explosive concentrations of dust may cause explosions if ignited by hot or sparking objects. Such explosions may cause serious or fatal injuries to persons or severe material damage.

It is essential that the person responsible for the use of motors and frequency inverters in explosion hazard areas is trained in their correct use.

Repairs may only be carried out by Getriebebau NORD.

ATTENTION

At pulse frequencies above 6 kHz (400/480V devices) or 8 kHz (230V) devices, the reduction in power must be taken into account for the design of the drive unit.

If parameter (P218) is set to < 105%, the derating of the degree of modulation must be taken into account in the field reduction range.

2.10.2.5 Other options

M12 sockets and plugs for installation in the terminal box of the basic device or in technology units may only be used if they are approved for use in ATEX Zone 22 3D.

2.10.3 Maximum output voltage and torque reduction

As the maximum output voltage depends on the pulse frequency to be set, in some cases the torque which is stated in Planning Guideline 605 2101 must be reduced for values above the rated pulse frequency of 6 kHz.

For F

Therefore the maximum torque must be reduced by 1% for each kHz pulse frequency above 6 kHz. The torque limitation must be taken into account on reaching the break frequency. The same applies for the degree of modulation (P218). With the factory setting of 100%, in the field reduction range a torque reduction of 5% must be taken into account:

For P218 > 100%: T

Above a value of 105%, no reduction needs to be taken into account. However, with values above 105% no increase in torque above that of the Planning Guideline will be achieved. Under certain circumstances, degrees of modulation > 100% may lead to oscillations and motor vibration due to increased harmonics.

2.10.4 Commissioning information

For Zone 22 the cable glands must at least comply with protection class IP 55. Unused openings must be closed with blank screw caps suitable for ATEX Zone 22 3D (minimum protection class IP 55).

The motors are protected against overheating by means of the frequency inverter. This is carried out by the evaluation of the motor PTC by the frequency inverter. In order to ensure this function, the PTC must be connected to the intended input (Terminal 38/39 control terminal plug connector). In addition, care must be taken that a NORD motor from the motor list (P200) is set. If a standard 4-pole NORD motor or a motor from a different manufacturer is not used, the data for the motor parameters ((P201) to (P208)) must be adjusted to those on the motor rating plate. In addition, the frequency inverter must be parameterised so that the motor can be operated with a maximum speed of 3000 1/

2.11 Outdoor installation

The frequency inverter and the technology units can be installed outdoors under the following conditions:

 IP66 version (See Special Measures, Section 1.7)  UV-resistant blank screw caps. and inspection windows.

It is recommended that the frequency inverter is provided with a sun shield. The UV-resistant blind plugs and inspection glasses form part or the ATEX kit for the frequency inverter.

I.e. if the ATEX option for IP66 (Section 2.10) is used, all conditions for outdoor installation of the frequency inverter are fulfilled.

WARNING

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

The frequency inverter provides a series of optional expansion modules. These modules are preferably used for the direct control or connection of the frequency inverter to a higher level field bus.

The options are available both as an internal version for integration (into the FI), the so-called customer unit SK CU4-... or as an external version, the so-called technology unit SK TU4-… The differences between the internal and external options are merely limited to the number of additional IOs and the permissible current load of the connection terminals.

The internal customer interface (Customer Unit, SK CU4-...) is integrated into the frequency inverter. The electrical connection to the frequency inverter is usually made via the internal system bus. This is equipped with screw terminals for connection to external peripherals. As an option, there is also the possibility of using 4/5-pin M12 plug connectors in the FI housing.

3 Options

SK 1x0E with integrated customer unit SK 1x0E with attached technology unit

The external technology unit (Technology Unit, SK TU4-...) is externally attached to the frequency inverter and is therefore easy to access. The electrical connection to the frequency inverter is made via the internal system bus. External 4/5-pin plug connectors are available for use by the customer. A technology unit requires the use of a suitable SK TI4-TU-… connection unit. The optional wall mounting kit SK TIE4-WMK-TU also allows the technology units to be mounted close to the inverter.

The frequency inverter can manage the following options via its system bus:

 1 x ParameterBox SK PAR-3H and (via an RJ12 connector)  1 x Field bus option (e.g. Profibus DP), internal or external and  2 x I/O extension (SK xU4-IOE-…), internal and / or external

Up to 4 frequency inverters with their appropriate options can belong to a field bus.

3.1 Overview of optional modules

3.1.1 Overview of internal customer units SK CU4-…

Internal customer interfaces enable the expansion of the range of functions of the frequency inverter without changing its physical size. For example, either a field bus module or an I/O extension can be selected. The frequency inverter provides one slot for the fitting of an appropriate option. External options (technology units) are available for additionally required optional modules (Section 3.2.2).

The bus modules require an external 24 V supply. Therefore they are also available if the frequency inverter is not supplied from the mains, but the 24 V supply to the module is active.

3.1.2 Overview of external technology units SK TU4-…

External technology units enable the modular extension of the scope of frequency inverter functions. Users have access to both communication modules and an internal mains unit or an I/O expansion and

other modules.

Bus modules with connection terminals or M12 system connectors are available as options. Modules with protection class IP55 or optionally IP66 can be ordered according to the installation location.

They can be mounted directly on the frequency inverter, or separately using a suitable wall mounting kit. Each SK TU4-… Technology Unit requires an SK T14-TU-… Connection Unit. The SK T14-TU-BUS is

available for bus modules or the I/O extension. The SK TI4-TU-MSW must be used for the maintenance switch.

For the bus modules or I/O extension with integrated system bus an RJ12 socket (behind a transparent screw-on cover) is also available. This enables communication with other modules or frequency inverters. With this linkage, all devices can be parameterised by means of a ParameterBox SK PAR-3H or with a PC and the NORD CON software.

The bus modules require an external 24V supply. Therefore they are also available if the frequency inverter is not supplied from the mains, but the 24V supply to the module is active.

The analog inputs of SK 1x0 E series frequency inverters and the optional mains units SK xU4-24V can only

process unipolar setpoint values referenced to GND (0/2 … 10 V; 0/4 … 20 mA). If a bipolar setpoint (10V … + 10 V) is available, this must be converted to a 0 … 10 V signal by means of an SK CU4-REL setpoint

converter. Two coupling relays are integrated into the module. These are controlled via the digital outputs of the

frequency inverter and can be used as openers or closers according to their connection.

The terminal bar of the customer unit SK CU4-REL-… is divided into two potential levels (potential separation max. 50 V DC). On delivery, these are connected together with a plug-in jumper.

3 Options

The bipolar analog signals must be connected to input terminals 114 or 116. Via the analog outputs (Terminal 117 or 118) the signals which are transformed to 0...10V can be accessed and transferred to the frequency inverter for further processing. In order to ensure the function of the analog signal converter, the 10V DC reference voltage of the frequency inverter must be wired to the reference potential of the setpoint source(s) of the SK CU4-REL

Up to 2 digital signals can be transferred to the coupling relays from the frequency inverter. Regardless of the wiring, both relays each provide the possibility of accessing an opening (NC) or a closing (NO) signal.

The module must be supplied with 24V DC.

By the use of various modules for display, control and parameterisation, the frequency inverter can be easily adapted to various requirements.

Alphanumeric display and control modules (Section 4.2) can be used for simple commissioning. For more complex tasks, connection to a PC system and the use of NORD CON parameterisation software is available.

As supplied, without additional options, the diagnostic LED is externally visible. This indicates the actual status of the device. In contrast, the AS-i LED (SK 190E) is only visible if the device is open.

4.1 Diagnostic LEDs on the Frequency Inverter

The frequency inverter generates operating status messages. These messages (warnings, faults, switching statuses, measurement data) can be displayed with parameterisation tools (e.g. ParameterBox - see Section 4.2) (Parameter group P7xx). To a limited extent, the messages are also indicated via the diagnostic and status LEDs.

5 Commissioning

5.1 Factory settings

All frequency inverters supplied by Getriebebau NORD are pre-programmed with the default setting for standard applications with 4-pole standard motors (same voltage and power). For use with motors with other powers or number of poles, the data from the rating plate of the motor must be input into the parameters P201...P207 under the menu item >Motor data<.

NOTE: All motor data can be pre-set using parameter P200. After use of this function, this parameter

is reset to 0 = no change! The data is loaded automatically into parameters P201...P209 – and can be compared again with the data on the motor rating plate.

RECOMMENDATION: For the correct operation of the drive unit, it is necessary to input the motor data

(rating plate) as precisely as possible. In particular, an automatic stator resistance measurement using parameter P220 is recommended.

In order to automatically determine the stator resistance, set P220 = 1 and confirm by pressing "OK". The value calculated for the line resistance (dependent upon P207) will be saved in P208.

5.2 Commissioning of frequency inverters

The frequency inverter can be commissioned by adjustments to the parameters with software, using ParameterBox (SK CSX-3H or SK PAR-3H) or the PC-based software NORD CON. Here, the parameterised data is stored in the internal EEPROM.

5.2.1 Connection

After mounting the frequency inverter on the motor or the wall mounting kit, the mains and motor cables must be connected to the relevant terminals (PE, L1, N (/L2, L3) and U, V, W) (See sections 2.7 and 2.8).

In principle, the frequency inverter can be operated in this configuration. (See Section 5.2.3)

5.2.2.2 DIP switch configuration of the inverter

The analog inputs in the frequency inverter are suitable for current and voltage setpoints. For correct processing of current setpoints (0-20mA / 4-20mA) the relevant DIP switch (S1) must be set for current signals ("ON").

Adjustment to fail-safe signals in case of cable breaks (2-10V/4-20mA) is made via parameters 402 and 403.

A second DIP switch (S2) is also available, via which the system bus address can be specified or the system bus can be activated. This has priority over the parameters P509, P514 and P515.

All devices can be operated in the condition in which they are delivered. The standard motor data of a 4-pole IE1 standard asynchronous motor of the same power are parameterised. The PTC input must be bypassed, if a motor with PTC is not available. Parameter (P428) must be changed if an automatic start-up with "Mains On" is required.

5.2.3.1 Minimal configuration

The frequency inverter provides all the necessary low voltages (24V DC / 10V DC).

Minimal configuration with options

In order to implement completely autonomous operation (i.e. independent of control cables etc.) a potentiometer unit (SK CU4-POT) is required. In this way, the required speed and direction control can be achieved with only a single mains cable (single phase or three-phase, according to the version) (see connection example in Section 3.3.1).

5.3 KTY84-130 connection

The current vector control of the SK 1x0E series can be further optimised by the use of a KTY84-130 temperature sensor (R the highest precision of regulation by the frequency inverter and the associated optimum speed precision of the motor is achieved at all times. As the temperature measurement starts immediately after the (mains) switch-on of the frequency inverter, the frequency inverter provides immediate optimum control, even if the motor has a considerably increased temperature after an intermediate "Mains off / Mains on" of the frequency inverter.

Connection examples:

5.4 AS interface (only SK 190E)

5.4.1 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.

The SK 190E frequency inverter is an A/B slave, which corresponds to slave profile S-7.A. They can be administered by masters whose profile at least corresponds to class M4.

In contrast to devices with the profile S-7.0 devices with the profile S-7.A use the extended address range. Devices with slave profiles S-7.0 and S-7.A 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).

The yellow AS interface cable supplies data and energy. 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 correspondingly higher 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 also cause an additional doubling of the cycle time to max. 21ms.

The bus system is completely defined in the AS-Interface Complete Specification and is standardised as per EN 50295, IEC62026.

5.4.2 Features

The SK 190E frequency inverter versions provide an integrated AS interface as standard. Therefore, these devices can be directly integrated into an AS interface network. Only the adaptation of various frequency inverter functions, addressing and the correct connection of the power supply, BUS, sensor and actuator cables needs to be carried out.

Features

 Electrically isolated bus interface  Status display (1 LED) inside the device (can be viewed with the cover open)  Configuration by parameterisation  Slave profile S-7.A (4I / 4O), (A/B Slave)  Connection of the frequency inverter via the terminal bar, optionally via M12 flanged plug connector  Up to 31 standard slave (or 62 A/B slaves in the extended address region) on one bus conductor  Cycle time ≤ 5 ms / 10 ms (A/B)  Address as delivered = 0  Max. current consumption: 25 mA

The factory setting of the frequency inverter enables the immediate availability of common AS-i basic functions. These functions can be adapted by parameterisation.

5.4.3 Bus structure and topology

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. 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. 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 may be used for the power supply. This AS interface power supply is directly connected to the yellow standard cable (ASI+ and ASI- cable) and should be positioned as close as possible to the AS-i master in order to keep the voltage drop small.

Signal status LED / ASi-specific display With these devices, the status of the ASi interface is indicated by the dual colour LEDAS-i.

Control voltage - frequency inverter supply

The yellow ASi cable supplies the AS interface with the necessary control voltage. The control section of the frequency inverter is not supplied from the AS interface voltage.

Configuration The most important functions are assigned via the arrays [-01] … [-04] of parameter (P480) and (P481).

Addressing

In order to use a frequency inverter in an ASi network, this must be assigned with a unique address (1-31). The FI is set to address 1 as the factory setting, and can therefore be identified as a "new device" by the AS-i master (prerequisite for the automatic address assignment by the master).

In many other cases, addressing is carried out by means of a normal addressing device for AS-i slaves. The following should be noted:

Procedure for SK 190E:

 Ensure power supply of the ASi interface via the yellow ASi cable.  Disconnect the AS-i master during addressing  Set the address ≠ 0  Do not doubly assign addresses

Normal hand-held units can be used for the addressing of the frequency inverter. Typical manufacturers are Pepperl+Fuchs (e.g.: VBP-HH1-V3.0-V1) and IFM (E.g.: AC1154).

The following lists the possibilities for the practical implementation of addressing an SK 190E with an addressing box.

Version 1

With a normal addressing device (equipped with an M12 plug for connection to the AS-i bus) the AS-i can be integrated into the AS-i network via a suitable access point. The prerequisite for this is that the AS-i master can be switched off.

Version 2

With an addressing unit (equipped with an M12 plug for connection to the AS-i bus and an additional M12 plug for an external power supply), the addressing unit can be directly connected into the AS-i cable.

6 Parameterisation

The frequency inverter, field bus and I/O -extension modules each have their own logic systems. These can be adapted to customers' requirements by means of changeable parameters. The basic functions of the particular modules are factory-set, so that the units have basic functionalities on delivery. Limited adaptations of individual functions of the relevant devices can be implemented vie DIP switches. For all further adjustments, access to the parameters of the relevant device with the aid of a ParameterBox (SK PAR-3H, SK CSX-3H) or NORD CON software is essential. It should be noted that the hardware

configuration (DIP - switches) has priority over configuration via software (parameterisation). NOTE: For use on the SK 1x0E the ParameterBox SK PAR-3H must have at least the software

version 4.4 R2. The following describes the relevant parameters for the frequency inverter (Section 6.1) and the I/O

extension modules (Section 6.2). Explanation for parameters which relate to the field bus options can be obtained from the relevant supplementary manuals.

Availability of the parameters Due to certain configurations, the parameters are subject to certain conditions. The following tables (from

Section 6.1 onwards) list all parameters together with the particular information.

Array parameter display Some parameters have the option of displaying settings and views in several levels (arrays). After the

parameter is selected, the array level is displayed and must then also be selected.

6.1 Frequency inverter parameterisation

Every frequency inverter is factory-set for a motor of the same power. All parameters can be adjusted "online". There are four switchable parameter sets available during operation. As delivered, all parameters are visible; however, some can be hidden with parameter P003.

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

NOTE: Parameter P523 can be used to load the factory settings for all parameters at any time. This

can be helpful, e.g. during the commissioning of a frequency inverter whose parameters no longer correspond with the factory settings.

Acceleration time

(Acceleration time)

0.05 ... 320.00 sec { 2.00 }

Start-up time (acceleration ramp) is the time corresponding to the linear frequency rise from 0Hz to the set maximum frequency (P105). If an actual setpoint of <100% is being used, the acceleration time is reduced linearly according to the setpoint which is set.

The acceleration time can be extended by certain circumstances, e.g. FI overload, setpoint lag, smoothing, or if the current limit is reached.

Notes on ramp gradient:

Amongst other things, the ramp gradient is governed by the inertia of the rotor. A ramp with a gradient which is too steep may result in the "inversion" of the motor. In general, extremely steep ramps (e.g.: 0 - 50Hz in < 0.1 s) should be avoided, as may cause damage to the frequency inverter.

P103

Deceleration time

(Deceleration time)

0.05 ... 320.00 sec { 2.00 }

Deceleration time (braking ramp) is the time corresponding to the linear frequency reduction from the set maximum frequency (P105) to 0Hz. If an actual setpoint <100% is being used, the deceleration time reduces accordingly.

The braking time can be extended by certain circumstances, e.g. by the selected >Switch-off mode< (P108) or >Ramp smoothing< (P106).

Notes on ramp gradient: see parameter (P102)

P104

Minimum frequency

(Minimum frequency)

0.0 ... 400.0 Hz { 0.0 }

The minimum frequency is the frequency supplied by the FI as soon as it is enabled and no additional setpoint is set.

In combination with other setpoints (e.g. analog setpoint of fixed frequencies) these are added to the set minimum frequency.

This frequency is undershot when

a) the drive is accelerated from standstill. b) The FI is blocked. The frequency then reduces to the absolute minimum (P505)

before it is blocked.

c) The FI is reversing. The reverse in the rotation field takes place at the absolute

minimum frequency (P505).

This frequency can be continuously undershot if, during acceleration or braking, the function "Maintain frequency" (Function Digital input = 9) is executed.

P105

Maximum frequency

(Maximum frequency)

0.1 ... 400.0 Hz { 50.0 }

The frequency supplied by the FI after being enabled and once the maximum setpoint is present, e.g. analog setpoint corresponding to P403, a correspondingly fixed frequency or maximum via the SimpleBox / ParameterBox.

This frequency can only be overshot by the slip compensation (P212), the function "Maintain frequency" (function digital input = 9) or a change to another parameter set with lower maximum frequency.

Brake reaction time

(Brake reaction time)

0 ... 2.50 s { 0.00 }

Electromagnetic brakes have a physically-dependent delayed reaction time when actuated. This can cause a dropping of the load for lifting applications, as the brake only takes over the load after a delay.

This reaction time can be taken into account under parameter (P107). Within the adjustable application time, the FI supplies the set absolute minimum frequency (P505)

and so prevents movement against the brake and load drop when stopping. See also the parameter >Release time< (P114) NOTE: The optional module SK CU4-MBR must be used for the control of electromagnetic

brakes (especially for lifting gear). The minimum absolute frequency (P505) should never be less than 2.0Hz.

NOTE: If a time > 0 is set in (P107) or (P114), at the moment the FI is switched on, the level

of the excitation current (field current) is checked. If no magnetising current is present, the FI remains in magnetising mode and the motor brake is not released.

NOTE: If brake control is used, care must be taken that parameter (P107) is not set to 0

Disconnection mode

(Disconnection mode)

S P

0 ... 13 { 1 }

This parameter determines the manner in which the output frequency is reduced after "Blocking" (controller enable  low).

0 = Voltage block: The output signal is switched off immediately. The FI no longer supplies

an output frequency. In this case, the motor is braked only by mechanical friction. Immediately switching the FI on again can lead to an error message.

1 = Ramp: The current output frequency is reduced in proportion to the remaining

deceleration time, from P103/P105.

2 = Ramp with delay: as with ramp, however for generational operation the brake ramp is

extended, or for static operation the output frequency is increased. Under certain conditions, this function can prevent overload switch off or reduce brake resistance power dissipation.

NOTE: This function must not be programmed if defined deceleration is required, e.g. with lifting mechanisms.

3 = Immediate DC braking: The FI switches immediately to the preselected DC current

(P109). This DC current is supplied for the remaining proportion of the >DC brake time< (P110). Depending on the relationship, actual output frequency to max. frequency (P105), the >DC braking time< is shortened. The time taken for the motor to stop depends on the application. This deceleration time depends of the moment of inertial of the load and the DC current which is set (P109). With this type of braking, no energy is fed back to the FI. Heat losses occur, mainly in the rotor of the motor.

4 = Const. brake distance, „Constant brake distance“: The brake ramp is delayed in starting

if the equipment is not being driven at the maximum output frequency (P105). This results in an approximately similar braking distance for different frequencies.

NOTE: This function cannot be used as a positioning function. This function should not be combined with ramp smoothing (P106).

5 = Combined braking, „Combined braking“: Dependent on the actual link voltage, a high

frequency voltage is switched to the basic frequency (linear characteristic curves only, P211 = 0 and P212 = 0). The deceleration time is retained where possible (P103).  additional motor warming!

6 = Quadratic ramp: The brake ramp does not follow a linear path, but rather a decreasing

quadratic one.

Current setting for the functions of DC current braking (P108 = 3) and combined braking (P108 = 5). The correct setting value depends on the mechanical load and the required deceleration time.

A higher setting brings large loads to a standstill more quickly. The 100% setting relates to a current value as stored in the >Nominal current< parameter P203. NOTE: The amount of DC current (0 Hz) which the FI can supply is limited. For this value,

(P factor torque limit)

S P

25 ... 400 % { 100 }

Directly affects the behaviour of the drive at torque limit. The basic setting of 100% is sufficient for most drive tasks.

If the value is too large, the drive unit will tend to oscillate when the torque limit is reached. If the value is too small, the programmed torque limit may be undershot.

P112

Torque current limit

(Torque current limit)

S P

25 ... 400 % / 401 { 401 }

With this parameter, a limit value for the torque-generating current can be set. This can prevent mechanical overloading of the drive. It cannot provide any protection against mechanical blockages (movement to stops). A slipping clutch which acts as a safety device must be provided.

The torque current limit can also be set over an infinite range of settings using an analog input. The maximum setpoint (compare adjustment 100%, P403[-01] . .[-06]) then corresponds to the value set in P112.

The limit value 20% of current torque cannot be undershot by a smaller analog setpoint (P400[-01] … [-09] = 11 or 12).

401 = OFF means the switch-off of the torque current limit! This is also the basic setting for the FI.

Electromagnetic brakes have a delayed reaction time during ventilation, which depends on physical factors. This can lead to the motor running while the brake is still applied, which will cause the inverter to switch off with an overcurrent report.

This release time can be taken into account in parameter P114 (Brake control). During the adjustable ventilation time, the FI supplies the set absolute minimum frequency (P505)

thus preventing movement against the brake. See also the parameter >Brake reaction time< P107 (setting example). NOTE: If the brake release time is set to "0", then P107 is the brake release and reaction

Motor stator resistance  restistance of a phase winding with a DC motor. Has a direct influence on the current control of the FI. Too high a value will result in a possible

overcurrent, on the other hand a value which is too low will result in a motor torque which is too low. The parameter P220 can be used for simple measurement. Parameter P208 can be used for

manual setting or as information about the result of an automatic measurement. NOTE: For optimum functioning of the current vector control, the stator resistance must be

automatically measured by the FI.

P210

Static boost

(Static boost)

The static boost affects the current that generates the magnetic field. This is equivalent to the no load current of the respective motor and is therefore load-independent. The no load current is calculated using the motor data. The factory setting of 100% is sufficient for normal applications.

P211

The dynamic boost affects the torque generating current and is therefore a load-dependent parameter. The factory 100% setting is also sufficient for typical applications.

Too high a value can lead to overcurrent in the FI. Under load therefore, the output voltage will be raised too sharply. Too low a value will lead to insufficient torque.

Slip compensation

(Slip compensation)

S P

0 ... 150 % { 100 }

The slip compensation increases the output frequency, dependent on load, to keep the asynchronous motor speed approximately constant.

The factory setting of 100% is optimal when using DC asynchronous motors and correct motor data has been set.

If several motors (different loads or outputs) are operated with one FI, the slip compensation P212 must be set to 0%. This rules out a negative influence. This is equally valid for synchronous motors that do not have slip due to their design.

P213

Amplification ISD control

(amplification of ISD control)

S P

25 ... 400 % { 100 }

This parameter influences the control dynamics of the FI current vector control (ISD control). Higher settings make the controller faster, lower settings slower.

Dependent on application type, this parameter can be altered, e.g. to avoid unstable operation

P214

Torque precontrol

(Torque precontrol)

S P

-200 ... 200 % { 0 }

This function allows a value for the expected torque requirement to be set in the controller. This function can be used in lifting applications for a better load transfer during start-up.

NOTE:Motor torques (with rotation field right) are entered with a positive sign, generator torques are entered with a negative sign. The reverse applies for the counter clockwise rotation.

P215

Boost precontrol

(Boost precontrol)

S P

0 ... 200 % { 0 }

Only advisable with linear characteristic curve (P211 = 0% and P212 = 0%). For drives that require a high starting torque, this parameter provides an option for switching in

an additional current during the start phase. The application time is limited and can be selected at parameter >Time boost precontrol< P216.

All current and torque current limits that may have been set (P112 and P536, P537) are deactivated during the boost lead time.

Note: With active ISD control (P211 and / or P212 ≠ 0) parameterisation of P216 ≠ 0 results

in incorrect control.

P217

Oscillation damping

(Oscillation damping)

S P

0 ... 400 % { 10 }

With the oscillation damping, idling current harmonics can be damped. Parameter 217 is a measure of the damping power.

For oscillation damping the oscillation component is filtered out of the torque current by means of a high pass filter. This is amplified by P217, inverted and switched to the output frequency.

The limit for the value switched is also proportional to P217. The time constant for the high pass filter depends on P213. For higher values of P213 the time constant is lower.

With a set value of 10% for P217, a maximum of ± 0.045 Hz are switched in. At 400% in P217, this corresponds to ± 1.8 Hz

P218

Modulation depth

(Modulation depth)

50 ... 110 % { 100 }

This setting influences the maximum possible output voltage of the FI in relation to the mains voltage. Values <100% reduce the voltage to values below that of the mains voltage if this is required for motors. Values >100% increase the output voltage to the motor increased the harmonics in the current, which may cause swinging in some motors.

Normally, 100% should be set.

P219

Auto. Magn.adjustm.

(Automatic magnetisation adjustment)

25 ... 100 % / 101 { 100 }

With this parameter, an automatic adjustment of the magnetizing to the motor load can be made. P219 is a limiting value, to which the field in the motor can be reduced.

As standard, the value is set to 100%, and therefore no reduction is possible. As minimum, 25% can be set.

The reduction of the field is performed with a time constant of approx. 7.5 sec. On increase of load the field is built up again with a time constant of approx. 300 ms. The reduction of the field is carried out so that the magnetisation current and the torque current are approximately equal, so that the motor is operated with “optimum efficiency”. An increase of the field above the setpoint value is not intended.

This function is intended for applications in which the required torque only changes slowly (e.g. pumps and fans). Its effect therefore replaces a quadratic curve, as it adapts the voltage to the load.

NOTE: This must not be used for lifting or applications where a more rapid build-up of the

torque is required, as otherwise there would be overcurrent switch-offs or inversion of the motor on sudden changes of load, because the missing field would have be compensated by a disproportionate torque current.

101 = automatic, with the setting P219=101 an automatic magnetisation current controller is

activated. The ISD controller then operates with a subordinate magnetizing controller, which improves the slippage calculation, especially at higher loads. The control times are considerably faster compared to the Normal ISD control (P219 = 100)

Para. identification

(Parameter identification)

0... 2 { 0 } Duration up to 240 s

The motor data is automatically determined by the FI with this parameter. In most cases this leads to considerably better drive characteristics, as DC asynchronous motors are subject to manufacturing tolerances which are not documented on the rating plate.

If unfavorable operating characteristics result, select a suitable motor in P200 or set the parameters P201 … P208 manually.

0 = No identification 1 = Identification RS: only the stator resistance (display in P208) is determined. 2 = Motor identification: all motor parameters (P202, P203, P206, P208, P209) are

determined.

Procedure:

a) The identification should be made with the motor cold. Warming up of the motor during

operation is automatically taken into account.

b) The FI must be in an “operative condition”‘. For Bus operation, the Bus must be

operating without error. The FI must not be in a state of switch-on block.

c) The motor power may only be one power level greater or 3 power levels lower than the

nominal power of the FI.

d) The motor data should be set according to the rating plate or P200. However, at least

the nominal frequency (P201), the nominal speed (P202), the voltage (P204), the power (P205) and the motor circuit (P207) should be known.

e) If the identification cannot be concluded successfully, the error message E019 is

generated. See also Section 6, Error messages.

f) Reliable identification can be made with motor cables up 20m in length.

NOTE: After identification of parameters, P220 is again = 0. Care must be taken that the connection to the motor is not interrupted during the

entire measuring process.

E.g. internal setpoint with reversal of direction of rotation: P402 = 5V, P104 = 0 Hz, Potentiometer 0–10 V  Rotation direction change at 5V in mid-range setting of the potentiometer.

At the moment of reversal (hysteresis =  P505), the drive stands still when the minimum frequency (P104) is smaller than the absolute minimum frequency (P505). A brake that is controlled by the FI will have entered the hysteresis range.

If the minimum frequency (P104) is greater than the absolute minimum frequency (P505), the drive reverses when the minimum frequency is reached. In the hysteresis range  P104, the FI supplies the minimum frequency (P104), the brake controlled by the FI is not applied.

NOTE: The SK xU4-IOE provides the frequency inverter with a value standardised to 0…100%.

if the setpoint value is undershot by a value of 2mA, the inverter output is switched off.

NOTE: Settings of parameters (P402) and (P403) are treated in an additive manner, i.e. they

can be used for additional adjustment of the limiting values.

3 = - 10V – 10 V: If a setpoint smaller than the programmed adjustment 0% (P402) is

-10.0 ... 10.0 V { 5.0 }

Fixed specification of a setpoint for the process controller that will only occasionally be altered. Only with P400 = 6 or 7 (PID process controller). Further details can be found in Section 9.2 .

P413

P-component PI-controller

(P-component of PI-controller)

S P

0.0 ... 400.0 % { 10.0 }

This parameter is only effective when the function PI controller actual frequency is selected. The P-component of the PI controller determines the frequency jump if there is a control deviation

based on the control difference. E.g.: At a setting of P413 = 10% and a rule difference of 50%, 5% is added to the actual setpoint.

P414

I-component PI-controller

(I-component of PI-controller)

S P

0.0 ... 3,000.0 %/s { 10.0 }

This parameter is only effective when the function PI controller actual frequency is selected. The I-component of the PI controller determines the frequency change, dependent on time. Note: In contrast to other NORD series, parameter P414 is smaller by a factor of 100

(Reason: better setting ability with small I-components).

P415

Process controller limit

In the analog output function an offset can be entered to simplify the processing of the analog signal in other equipment.

If the analog output has been programmed with a digital function, then the difference between the switch-on point and the switch-off point can be set in this parameter (hysteresis).

Analog functions (max. load: 5mA analog): An analog voltage (0 ... +10 Volt) can be taken from the control terminals (max. 5mA). Various

functions are available, whereby: 0 Volt analog voltage always corresponds to 0% of the selected value. 10 V always corresponds to the motor nominal values (unless otherwise stated) multiplied by the

P419 standardisation factor, e.g.:

For standardisation of actual values: See also (Section 9.9 ).

0 = No function, no output signal at the terminals. 1 = Actual frequency *, the analog voltage is proportional to the FI output frequency.

(100%=(P201))

2 = Actual speed *, this is the synchronous speed calculated by the FI based on the existing

setpoint. Load-dependent speed fluctuations are not taken into account.

3 = Current *, the effective value of the output current supplied by the FI. (100%=(P203)) 4 = Torque current *, displays the motor load torque calculated by the FI. (100% = (P112)) 5 = Voltage *, the output voltage supplied by the FI. (100%=(P204)) 6 = Link voltage, "Link circuit voltage", is the DC voltage in the FI. This is not based on the

motor rated data. 10V Volt, standardised at 100%, is equivalent to 450V DC (230V mains) or 850 Volt DC (480V mains)!

7 = Value from P542, the analog output can be set using parameter P542 independently of

the actual operating status of the FI. For example, with Bus switching (parameter command) this function can supply an analog value from the FI, which is triggered by the control unit.

8 = Apparent power *, the actual apparent power of the motor as calculated by the FI.

(100%=(P203)*(P204) or = (P203)*(P204)*√3)

9 = Effective power *, the actual effective power calculated by the FI.

(100%=(P203)*(P204)*(P206) bzw = (P203)*(P204)*(P206)*√3)

10 = Torque [%]: the actual torque calculated by the FI (100%=Nominal motor torque). 11 = Field [%] *, the actual field in the motor calculated by the FI. 12 = Actual frequency ±*, the analog voltage is proportional to the output frequency of the FI,

whereby the zero point is shifted to 5V. For rotation to the right, values between 5V and 10V are output, and for rotation to the left values between 5V and 0V.

13 = Actual speed ± *, is the synchronic rotation speed calculated by the FI, based on the

current setpoint, where the null point has been shifted to 5V. For rotation to the right, values from 5V to 10V are output and for rotation to the left, values from 5V to 0V. The measured speed is output via this function if servo mode is used.

14 = Torque [%] ± *, is the actual torque calculated by the FI, whereby the zero point is shifted

to 5 V. For drive torques, values between 5V and 10V are output, and for generator torque, values between 5V and 0V.

29 = Reserved 30 = Set freq befor ramp, "Setpoint frequency before frequency ramp", displays the frequency

produced by any upstream controllers (ISD, PID, etc.). This is then the setpoint frequency for the power stage after it has been adjusted by the start-up or braking ramp (P102, P103).

31 = Output via BUS PZD, the analog output is controlled via a bus system. The process data

is directly transferred (P546, P547, P548).

33 = Setpoint freq. Motor pot, "Setpoint frequency of motor potentiometer"

Using this parameter an adjustment can be made to the analog output for the selected operating zone. The maximum analog output (10 V) corresponds to the standardisation value of the appropriate selection.

If therefore, at a constant working point, this parameter is raised from 100% to 200%, the analog output voltage is halved. 10 Volt output signal then corresponds to twice the nominal value.

For negative values the logic is reversed. An actual value of 0% will then produce 10 V at the output and -100% will produce 0 V.
