HARDWARE
(continued)
Standard I/O The unit provides basic I/O connections
directly to suit common applications for NXL.
I/O Board NXOPTAA Additional control inputs and
outputs are provided by the NXOPTAA I/O board (3 x
digital inputs, 1 x digital relay output, and 1 x digital
open collector output). It is fitted as standard to the
Ecodrives and can be fitted as an optional extra to the
Microdrives.
Control Keypad: The control keypad is used for parameter
setting, reading status data, and giving control commands. It is
detachable and can be operated externally being connected via
a cable to the frequency converter. A PC can be connected and
used to control the frequency converter instead of the control
keypad. (A 1.5 m, 9 way D type male to female extension cable
is available, ACC/NXL/RS232PC. A door mounting kit including a
2m cable is available, NXLDRA.)
The Trend 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/BusComm). 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 buttons
serve the purposes of parameter setting and value monitoring.
