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,
READY, STOP, ALARM, FAULT)
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.
