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 Int
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
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.
