CONTROL KEYPAD

The control keypad is the link between the frequency converter and the user. The NX control keypad
features an alphanumeric display with seven indicators for the Run status (RUN,
ALARM, FAULT) and three indicators for the control place (I/O term/ Keypad/BusComm). There are also
three Status Indicator LEDs (green - green - red), see Status LEDs (green – green – red) below.
The control information, i.e. the number of menu, description of menu or the displayed value and the
numeric information are presented on three text lines.
The frequency converter is operable through the nine push-buttons of the control keypad. Furthermore, the
buttons serve the purposes of parameter setting and value monitoring.
The keypad is detachable and isolated from the input line potential.
