7. CONTROL KEYPAD
The control keypad is the link between the VACON
®
AC drive 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 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 AC drive 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.
