SK 105E…175E Motor Starter Manual
6 Pre-series version BU 0135 GB-2713
1 General information
The SK 1x5E series is based on the tried and tested NORD platform. These devices feature a compact
design with optimum characteristics.
Due to dual phase control, not only a pure motor start, but also a soft start is possible. The phase control
process was selected so that the resulting harmonic torques are kept as low as possible. A comprehensive
spectrum of monitoring functions rounds off the range.
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 operating all three-phase motors.
The power range is from 0.25kW to 7.5kW. The device is equipped with an integrated mains filter.
This manual is based on the device software V1.0 R0 (see P707) of the motor starter. If the motor starter
uses a different software version, this may cause differences. If necessary, the latest manual should be
downloaded from the Internet (
www.nord.com ).
For the various versions of the device series SK 105E…SK 175E there are differences in functions, the
integrated AS interface or the integrated PROFIBUS interface.
Typically, this series of devices is installed directly on a three-phase asynchronous motor. Alternatively,
optional accessories are available for mounting the devices close to the motor, e.g. on the wall or on a
machine frame.
In the simplest configuration, even without a PC or control box, all of the most important parameters can be
set using up to four potentiometers and the four DIP switches. LEDs are provided for the diagnostics of the
operating status. The use of a control module is therefore not absolutely necessary.
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 user are saved in the flash memory of the device.
A permanent connection via the RS 232 interface is not intended for normal operation.
