4 Displays and control

By the use of various modules for display, control and parameterisation, the frequency inverter can be easily
adapted to various requirements.

Alphanumeric display and control modules (Section 4.2) can be used for simple commissioning. For more
complex tasks, connection to a PC system and the use of NORD CON parameterisation software is
available.

As supplied, without additional options, the diagnostic LED is externally visible. This indicates the actual
status of the device. In contrast, the AS-i LED (SK 190E) is only visible if the device is open.

4.1 Diagnostic LEDs on the Frequency Inverter

The frequency inverter generates operating status messages. These messages (warnings, faults, switching
statuses, measurement data) can be displayed with parameterisation tools (e.g. ParameterBox - see
Section 4.2) (Parameter group P7xx). To a limited extent, the messages are also indicated via the
diagnostic and status LEDs.
