NORDAC BASE (SK 180E / SK 190E) – Users Manual for Frequency Inverters
10 BU 0180 en-4118
1 General
The SK 1x0E series is based on the tried and tested NORD platform. The devices are characterised
by their compact design and optimum control characteristics, and have uniform parametrisation.
The devices have sensor-less current vector control with a wide range of settings. In combination with
suitable motor models, which always provide an optimised voltage/frequency ratio, all three-phase
asynchronous motors that are suitable for inverter operation and permanently excited synchronous
motors can be driven. For the drive unit, this means very high starting and overload torques with
constant speed.
The performance range extends from 0.25 kW bis 2.2 kW.
The use of modular modules means that the device series can be adapted to individual customer
requirements.
This manual is based on the device software as stated in the version list (see P707). If the frequency
inverter uses a different software version, this may cause differences. If necessary, the current manual
can be downloaded from the Internet (http://www.nord.com/).
Additional descriptions for optional functions and bus systems exist (http://www.nord.com/).
Information Accessories
The accessories mentioned in the manual are also subject to change. Current details of these are summarised in
separate data sheets, which are available at www.nord.com under the heading Documentation → Manuals →
Electronic Drive Technology → Techn. Info / Data Sheet. The data sheets available at the date of publication of
this manual are listed by name in the relevant sections (TI ...).
Installation directly on a motor is typical of this device series. Alternatively, optional accessories are
also available for mounting the devices close to the motor, e.g. on the wall or on a machine frame.
In order to have access to all parameters, the internal RS232 interface (access via RJ12 connection)
can be used. Access to the parameters takes place via an optional SimpleBox or ParameterBox, for
example.
The parameter settings modified by the operator are backed up in the integrated, non-volatile memory
of the device.
1.1 Overview
This manual describes all of the possible functions and equipment. The equipment and functionality
are limited according to the type of device.
Basic characteristics
• High starting torque and precise motor speed control setting by means of sensorless current vector
control
• Can be installed directly on, or close to the motor.
• Permissible ambient temperature -25°C to 50°C (please refer to technical data)
• Integrated EMC mains filter for limit curve B, Category C1, motor-mounted (not with 115 V devices)
• Automatic measurement of stator resistance and determination of the exact motor data possible
• Programmable direct current braking
• Size 2 only: Built-in brake chopper for 4 quadrant operation, optional braking resistors (internal /
external)
• 2 analogue inputs (switchable between current and voltage operation), which can also be used as
digital inputs.
• 3 digital inputs

1 General
BU 0180 en-4118 11
• 2 digital outputs
• Separate temperature sensor input (TF+/TF-)
• NORD system bus for connecting additional modules, with switchable terminating resistance and
address which can be set using DIP switches.
• Four separate parameter sets, switchable online
• LEDs for diagnosis
• RS232/485 interface via RJ12 plug
• Operation of three-phase current Asynchronous Motors (ASM) and Permanent Magnet
Synchronous Motors (PMSM)
• Integrated PLC (BU 0550)
Additional features of the SK 190E
• Integrated AS Interface
Option modules
Option modules are used to extend the functionality of the device.
These options are available as an installation variant, the so-called SK CU4-… customer unit, and also
as an attachment variant, the so-called SK TU4-… technology unit. As well as the mechanical
differences, the installation and attachment variants also have some functional differences.
Figure 1: Device with internal SK CU4-... Figure 2: Device with external SK CU4-...
Attachment variant
The external technology unit (Technology Unit SK TU4-…) is externally attached to the device and
is therefore easy to access.
A technology unit basically requires the use of a suitable SK TI4-TU-… connection unit.
The power supply and signal lines are connected using the screw clamps of the connection unit.
Depending on the version, additional connections for connectors (e.g. M12 or RJ45) may be available.
The optional wall mounting kit SK TIE4-WMK-TU also allows the technology units to be mounted away
from the starter.
Built-in variant
The internal customer unit (Customer Unit, SK CU4-...) is integrated in the device. The power
supply and signal lines are connected using screw clamps.

NORDAC BASE (SK 180E / SK 190E) – Users Manual for Frequency Inverters
12 BU 0180 en-4118
The SK CU4-POT potentiometer adapter is an exception among the "SK CU4 Modules", since it is not
integrated in the device but attached to it.
Communication between "intelligent" option modules and the device takes place via the system bus.
Intelligent option modules are modules with their own processor and communication technology, as is
the case with field bus modules, for example.
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 be connected to a system bus.

1.4 Safety, installation and operating instructions
Before working on or with the device, please read the following safety instructions extremely carefully.
Please pay attention to all other information from the device manual.
Non-compliance can result in serious or fatal injuries and damage to the device or its surroundings.
These safety instructions must be kept in a safe place!
1. General
Do not use defective devices or devices with defective or damaged housings or missing covers (e.g.
blind plugs for cable glands). Otherwise there is a risk of serious or fatal injuries caused by electric
shock or bursting electrical components such as powerful electrolytic capacitors.
Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of
serious personal injury or material damage.
During operation and depending on the protection class of the devices, there may be live, bare,
moving or rotating parts or hot surfaces.
The device operates with a dangerous voltage. Dangerous voltage may be present at the supply lines,
contact strips and PCBs of all connecting terminals (e.g. mains input, motor connection), even if the
device is not working or the motor is not rotating (e.g. caused by electronic disabling, jamming of the
drive or a short circuit at the output terminals).
The device is not equipped with a mains switch and is therefore always live when connected to the
power supply. Voltages may therefore be connected to a connected motor at standstill.
Even if the drive unit has been disconnected from the mains, a connected motor may rotate and
possibly generate a dangerous voltage.
If you come into contact with dangerous voltage such as this, there is a risk of an electric shock, which
can lead to serious or fatal injuries.
The device and any power plug connectors must not be disconnected while a voltage is applied to the
device. Failure to comply with this may cause arcing, which in addition to the risk of injury, also results
in a risk of damage or destruction of the device.
The fact that the status LED or other indicators are not illuminated does not indicate that the device
has been disconnected from the mains and is without voltage.
The heat sink and all other metal components can heat up to temperatures above 70 °C.
Touching these parts can result in local burns to the body parts concerned (cooling times and
clearance from neighbouring components must be complied with).
All work on the device, e.g. transportation, installation, commissioning and maintenance work must be
carried out by qualified experts (observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 and
IEC 664 or DIN VDE 0110 and national accident prevention regulations). In particular, the general and
regional installation and safety regulations for work on high voltage systems (e.g. VDE) must be
complied with as must the regulations concerning correct use of tools and the use of personal
protection equipment.
During all work on the device, take care that no foreign bodies, loose parts, moisture or dust enter or
remain in the device (risk of short circuit, fire and corrosion).
Further information can be found in this documentation.

must not be connected to the devices.
The devices are components intended for installation in electrical systems or machines.
Technical data and information for connection conditions can be found on the rating plate and in the
documentation, and must be complied with.
The devices may only be used for safety functions which are described and explicitly approved.
CE-labelled devices fulfil the requirements of the Low Voltage Directive 2014/35/EU. The stated
harmonized standards for the devices are used in the declaration of conformity.
a. Supplement: Correct purpose of use within the European Union
When installed in machines, the devices must not be commissioned (i.e. commencement of
proper use) until it has been ensured that the machine fulfils the provisions of EC Directive
2006/42/EC (Machinery Directive); EN 60204-1 must also be complied with.
Commissioning (i.e. start-up of proper use) is only permitted if the EMC directive (2014/30/EU)
has been complied with.
b. Supplement: Correct purpose of use outside the European Union
The local conditions of the operator for the installation and commissioning of the device must be
complied with at the usage location (see also "a) Supplement: Correct purpose of use within the
European Union").

Installation and assembly
The installation and cooling of the device must be implemented according to the regulations in the
corresponding documentation. The permissible mechanical and climatic ambient conditions (see
technical data in the manual for the device) must be complied with.
The device must be protected against impermissible loads. In particular, components must not be
deformed and/or insulation distances must not be changed. Touching of electronic components and
contacts must be avoided.
The device and its optional modules contain electrostatically sensitive components, which can be
easily damaged by incorrect handling. Electrical components must not be mechanically damaged or
destroyed.
Electrical Connection
Ensure that the device and the motor are specified for the correct supply voltage.
Installation, maintenance and repair work must not be carried out unless the device has been
disconnected from the voltage and at least 5 minutes have elapsed since the mains was switched off!
(Due to charged capacitors, the equipment may continue to carry hazardous voltages for up to
5 minutes after being switched off at the mains). Before starting work it is essential to check by
measurement that all contacts of the power plug connections or the connection are voltage-free.
The electrical installation must be implemented as per the applicable regulations (e.g. cable cross-
section, fuses, earth lead connections). Further instructions can be found in the documentation or
manual for the device.
Information regarding EMC-compliant installation such as shielding, earthing, location of filters and
routing of cables can be found in the documentation for the devices and in the technical information
manual TI 80-0011. CE marked devices must also comply with these instructions. Compliance with the
limit values specified in the EMC regulations is the responsibility of the manufacturer of the system or
machine.
In case of a fault, insufficient earthing may cause an electric shock with possibly fatal consequences if
the device is touched.
The device may only be operated with effective earth connections which comply with local regulations
for large leakage currents (> 3.5 mA). Detailed information regarding connections and operating
conditions can be obtained from the technical Information manual TI 80-0019.
The voltage supply of the device may directly or indirectly put it into operation, or touching electrically
conducting components may then cause an electric shock with possible fatal consequences.
All phases of all power connections (e.g. power supply) must always be disconnected.
Set-up, troubleshooting and commissioning
When working on live devices, the applicable national accident prevention regulations must be
complied with (e.g. BGV A3, formerly VBG 4).
The voltage supply of the device may directly or indirectly put it into operation, or touching electrically
conducting components may then cause an electric shock with possible fatal consequences.
The parametrisation and configuration of the devices must be selected so that no hazards can occur.
With certain setting conditions, the device or the motor which is connected to it may start automatically
when the mains are switched on. The machinery which it drives (press / chain hoist / roller / fan etc.)
may then make an unexpected movement. This may cause various injuries, including to third parties.
Before switching on the mains, secure the danger area by warning and removing all persons from the
danger area.

NORDAC BASE (SK 180E / SK 190E) – Users Manual for Frequency Inverters

Operation
Where necessary, systems in which the devices are installed must be equipped with additional
monitoring and protective equipment according to the applicable safety requirements (e.g. legislation
concerning technical equipment, accident prevention regulations, etc.).
All covers must be kept closed during operation.
With certain setting conditions, the device or the motor which is connected to it may start automatically
when the mains are switched on. The machinery which it drives (press / chain hoist / roller / fan etc.)
may then make an unexpected movement. This may cause various injuries, including to third parties.
Before switching on the mains, secure the danger area by warning and removing all persons from the
danger area.
Due to its operation, the device produces noises within the audible frequency range. These noises
may cause long-term stress, discomfort and fatigue, with negative effects on concentration. The
frequency range or the noise can be shifted to a less disturbing or almost inaudible range by
adjustment of the pulse frequency. However, this may possibly result in derating (lower power) of the
device.
Maintenance, repair and decommissioning
Installation, maintenance and repair work must not be carried out unless the device has been
disconnected from the voltage and at least 5 minutes have elapsed since the mains was switched off!
(Due to charged capacitors, the equipment may continue to carry hazardous voltages for up to
5 minutes after being switched off at the mains). Before starting work it is essential to check by
measurement that all contacts of the power plug connections or the connection are voltage-free.
For further information, please refer to the manual for the device.
