3 Options
3.1 Modular options
By combining various modules for display, control and parameterisation, the NORDAC SK 750E can be easily
adapted to various requirements.
Modules are available for processing analog and digital signals and for all common Bus systems.
Alphanumerical display and operating modules can be used for simple commissioning. For more complex
tasks, various connections to a PC or an automation system can be selected.
Technology units (Technology Unit, SK TU2-...) are located on the frequency inverter and are accessible
from the outside for manual control or parameterisation, or to provide connection to field bus systems.
Customer interfaces (Customer Unit, SK CU1-...) are installed inside the frequency inverter. These allow
control with analog and digital signals or connection to the bus systems.
Special extension units (Extension Unit, SK XU1-...) include special functions such as speed control with
incremental encoders or position control with incremental or absolute encoders.
WARNING
Modules must not be inserted or removed unless the device is free of voltage. The slots must only
be used for the intended modules.
Installation of a technology unit separate from the frequency inverter is not possible. It must be connected
directly to the frequency inverter.
NOTE
Further detailed information can be found in the Options manuals.
