TECHNICAL DATA 17(110)
The control keypad constitutes a link between the user and the frequency converter. The control keypad is
used for parameter setting, reading status data and giving control commands. It is detachable and can be
operated externally and connected via a cable to the frequency converter. Instead of the control keypad,
also a PC can be used to control the frequency converter if connected through a similar cable.
You can have your frequency converter equipped with a control I/O board which is either isolated (OPT-A8)
or not isolated (OPT-A1) from the ground.
The basic control interface and the parameters (the Basic Application) are easy to use. If a more versatile
interface or parameters are required, a more suitable application can be chosen from the "All in One" Appli-
cation Package. See the "All in One" Application Manual for more information on the different applications.
A brake resistor is available as internal option for frames FR4 to FR6 of voltage classes NX_2 and NX_5.
In all other frames of voltage classes NX_2 and NX_5, as well as in all frames of all other voltage classes,
the brake resistor is available as option and installed externally.
Optional I/O expander boards that increase the number of inputs and outputs to be used are also available.
