The control keypad provides 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.
Also a PC can be used instead of the control keypad, to control the frequency converter, if
connected through a similar cable.
Control I/O boards which are either isolated (NXOPTA8) or not isolated (NXOPTA1) from the
ground are available.
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
Application Package. See the Application Manual for more information on the different
applications.
A brake resistor is available as external or internal option for sizes FR6 and smaller and as
external option for FR7 and bigger. Optional I/O expander boards that increase the number of
inputs and outputs to be used are also available. For details please contact your nearest
Honeywell office or your local distributor (see back cover).
The input and output EMC filters have no influence on the basic functions of the frequency
converter. They are, however, necessary for the fulfilment of the EMC directives.
