BU 0700 GB-1411 Subject to technical alterations 21
Technology Units (TU) are modules that can be inserted from above for display,
parameterisation and control of the inverter.
3 Operation and display
The NORDAC SK 700E basic device is supplied with a blanking cover for the technology unit slot and the basic version has no
components for parameterisation or control.
Technology units, customer units and special extension units
Through the combination of modules for the display, technology units and modules with digital and analog inputs, as well as
interfaces, customer units or special extension units, the NORDAC SK 700E can be easily adapted to the requirements of
various applications.
WARNING
Modules should not be inserted or removed unless the device is free of voltage. The slots may only be used
for the applicable modules. The slots are coded to prevent them being mixed up.
Extension Units (XU) are inserted into the slot at the base of the inverter. Such an
extension unit is required if the speed is to be controlled or positioned by an incremental
(absolute) encoder.
Customer Units (CU) are modules inserted inside the inverter in the upper recess.
They are used for control and communication using digital/analog signals or bus
interfaces.
