General information

The NORDAC SK 200E 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 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 operating all three-phase motors. The
power range is from 0.25kW to 7.5kW with an integrated mains filter.
This manual is based on the device software V1.7 R1 (see P707) of the SK 200E. 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 (
For the SK 215E/225E/235E there are additional descriptions for functional safety (BU 0230), the integrated
AS interface (BU 0200, Section 2.7) and the positioning system (BU 0210). These contain all the necessary
additional information for start-up.
If a bus system is used for communication, a corresponding description (BU 0250) is provided, or this can
be downloaded from the Internet (
A typical feature of this series of devices is their installation directly on a three-phase asynchronous motor.
Alternatively, optional accessories are available for installation in the vicinity of the motor, e.g. on a wall or
on the frame of the machine.
In the simplest configuration, even without an EEPROM, there is the possibility of setting all important
parameters via two potentiometers and eight DIP switches. LEDs are provided for the diagnosis 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 have been
changed by the operator are stored in the plug-in EEPROM. The EEPROM must then always remain
plugged in during operation.
AS interface features (SK 225E/235E):
 Electrically isolated bus interface.
 Status indication with LED.
 Slave profile 7.0 with cyclical 4 Bit I/O data.
 Optional M12 connection.
 Up to 4 digital SK 225/235E inputs can be integrated.
 Up to 31 frequency inverters on one bus conductor (A-slave technology)
 Cycle time ≤ 5ms
