6 Operating status messages and LED displays
The frequency inverter generates operating status messages. These messages (warnings, errors, switching
statuses, measurement data) can be displayed with parameterisation tools (e.g. ParameterBox) (Parameter
group P7xx).
To a limited extent, the messages are also indicated via the diagnostic and status LEDs.
Error messages
Errors cause the frequency inverters to switch off, in order to prevent a device fault.
The following options are available to reset a fault (acknowledge):
1. Switching the mains off and on again,
2. By an appropriately programmed digital input (P420 = Function 12),
3. By switching of the “enable” on the frequency inverter to Low (if no digital input is programmed for
acknowledgement),
4. By Bus acknowledgement or
5. by P506, the automatic error acknowledgement.
An error message can only be acknowledged if its direct cause is no longer present.
