CONTROL KEYPAD
The control keypad is the link between the Vacon inverter and the user. The Vacon NX control keypad
features an alphanumeric display with seven indicators for the Run status (RUN,
, READY,
STOP, 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 section 7.1.3.
The control information, i.e. the menu number, description of the menu or the displayed value and
the numeric information are presented on three text lines.
The inverter is operable through the nine push-buttons of the control keypad. Furthermore, the
buttons can be used in setting parameters and monitoring values.
The keypad is detachable and isolated from the input line potential.
