Technology units (TU) are modules which can be inserted from
above for display, parameterisation and control of the inverter.
2.2 NORDAC SK 700E
With the combination of modules for display, technology units and modules with digital and analog inputs and
interfaces, customer interfaces or special extensions, the NORDAC SK 700E can easily be extended tot
cater for the requirements of a wide range of different applications.
Customer interfaces (Customer Units) are modules which are
inserted into the upper slot inside the inverter. They are used for
control and communication using digital/analog signals or bus
interfaces.
Special extensions (EXtension Units) are inserted into the lower slot of
the inverter. Such an extension unit is required if the speed is to be
controlled or positioned by an incremental (absolute) encoder.
WARNING
NOTE
Modules must not be inserted or removed unless the device is free of voltage. The slots may
only be used for the intended modules. The slots are coded to prevent them being mixed up.
Installation of a technology unit separate from the frequency inverter is not possible. It must be
connected directly to the frequency inverter.
