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
