6. Operating status messages
According to the cause, motor controllers and technology units generate appropriate messages if they
deviate from their normal operating status. There is a differentiation between warning and error
messages. If the frequency inverter is in the status "Start disabled", the reason for this can also be
displayed.
The messages generated for the motor controller are displayed in the corresponding array of
parameter (P700). The message displays for technology units are described in the relevant
supplementary instructions.
Frequency inverter switch-on block
If the frequency inverter is in the status "Not Ready" or "Start Disabled", the reason for this is indicated
in the third array element of parameter (P700).
Display is only possible with the NORD CON software or the ParameterBox.
Warning messages
Warning messages are generated as soon as a defined limit is reached. However this does not cause
the frequency inverter to switch off. These messages can be displayed via the array element [-02] in
parameter (P700) until either the reason for the warning is no longer present or the frequency inverter
has gone into a fault state with an error message.
Fault 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):
• by switching the mains off and on again,
• by an appropriately programmed digital input (P420 = Function 12),
• by switching off the “enable” on the frequency inverter
(if no digital input is programmed for acknowledgement),
• by Bus acknowledgement or
• by P506, the automatic error acknowledgement.

LED displays
The status of the FI is indicted by integrated status LEDs, which are visible from the outside in the
state as delivered. According to the type of FI, this is a two-colour LED (DS = DeviceState) or two
single-colour LEDs (DS DeviceState and DE = DeviceError).
Meaning: Green indicates readiness and the present of mains voltage. In operation, the
level of overload at the FI output is shown with an increasingly rapid flashing
code.
Red Signals the presence of an error by flashing according to the number
code of the error. This flashing code (e.g.: E003 = 3x flashing) indicates the
error groups.
