SK 2x5E with "PosiCon Functionality"
6 Subject to technical amendments BU 0210 GB
1 General information
NORDAC SK 2x5E frequency inverters are intermediate voltage circuit converters with fully digital
microprocessor technology for controlling the speed of 3-phase motors.
In combination with a HTL incremental encoder or a CANopen absolute encoder the standard components
form a high-precision positioning drive:
 The frequency inverter provides 15 programmable absolute positions.
 By means of the position control, the position is maintained even with large load fluctuations.
 Time-optimised and safe travel up to the target position by means of path calculation.
 In addition to travelling to absolute positions, up to 4 step lengths (so-called position increments)
can be stored in the frequency inverter.
 Required positions can also be transferred via a field bus interface.
 The positioning function is available as a standard function of the SK 2x5E.
The parameters (P6xx), which are required for positioning are input as an additional menu group (Positioning)
in the inverter menu structure, as soon as the functionality is enabled in the supervisor parameter (P003=3).
The specified setpoint position can be input via the existing digital inputs, the Bus IO In Bits, or via the USS
protocol or other field bus system.
A switchover from speed control to position control (Positioning) can be achieved by switching over the
parameters.
A synchronous operation functionality between a master and one or more slave drives is possible via the
integrated system bus interface.
A round axis function (Modulo axes) is also available for rotating platforms and similar applications. This
controls an endless axis with optimisation of travel. According to the required position, the drive rotates
clockwise or anticlockwise.
NOTE:
This manual BU 0210 GB only describes aspects which are directly related to the PosiCon functionality. All
standard functions and parameters of the inverter are contained in the Manual (BU 0200 GB).
Due to software updates the parameters described here may differ from those of your device. Therefore care
should be taken that both the current NordCon version and the version of your ParameterBox correspond to
the latest software version. In case of doubt, please contact your local NORD agency.
You can always find the latest version of this description on the Getriebebau NORD internet page.
