CONTROL KEYPAD
The control keypad is the link between the NXL frequency converter and the user. The NXL control
keypad features a seven-segment display with seven indicators for the Run status (RUN,
,
READY, STOP, ALARM, FAULT) and three indicators for the control place (I/O term, Keypad,
Bus/Comm).
The control information, i.e. the number of menu, the displayed value and the numeric information
are presented with numeric symbols.
The frequency converter is operable through the seven push-buttons of the control keypad.
Furthermore, the keypad serves the purposes of parameter setting and value monitoring.
The keypad is detachable and isolated from the input line potential.
