Status Word According To Fc Profile (Stw) - Danfoss VLT Midi Drive FC 280 Design Manual

RS485 Installation and Set-...
Bit 10, Data not valid/Data valid
Tell the frequency converter whether to use or ignore the
control word.
Bit 10=0: The control word is ignored.
Bit 10=1: The control word is used. This function is relevant
because the telegram always contains the control word,
regardless of the telegram type. If the control word is not
needed when updating or reading parameter, turn it off.
Bit 11, Relay 01
Bit 11=0: Relay not activated.
Bit 11=1: Relay 01 activated if [36] Control word bit 11 is
selected in parameter 5-40 Function Relay.
Bit 12, Relay 02
Bit 12=0: Relay 02 is not activated.
Bit 12=1: Relay 02 is activated if [37] Control word bit 12 is
selected in parameter 5-40 Function Relay.
Bit 13, Selection of set-up
Use bit 13 to select from the 2 menu set-ups according to
Table 5.36.
Set-up

2
Table 5.36 Menu Set-ups
The function is only possible when [9] Multi set-ups is
selected in parameter 0-10 Active Set-up.
To define how bit 13 gates with the corresponding
function on the digital inputs, use parameter 8-55 Set-up
Select.
Bit 15 Reverse
Bit 15=0: No reversing.
Bit 15=1: Reversing. In the default setting, reversing is set
to digital in parameter 8-54 Reversing Select. Bit 15 causes
reversing only when serial communication, [2] Logic OR or
[3] Logic AND is selected.

Table 5.37 Status Word According to FC Profile
Explanation of the status bits
Bit 00, Control not ready/ready
Bit 00=0: The frequency converter trips.
Bit 00=1: The frequency converter controls are ready but
the power component does not necessarily receive any
supply (if there is 24 V external supply to controls).
Bit 01, Frequency converter ready
Bit 01=0: The frequency converter is not ready.
Bit 01=1: The frequency converter is ready for operation.
Bit 02, Coast stop
Bit 02=0: The frequency converter releases the motor.
Bit 02=1: The frequency converter starts the motor with a
start command.
Bit 03, No error/trip
Bit 03=0: The frequency converter is not in fault mode.
Bit 03=1: The frequency converter trips. To re-establish
operation, press [Reset].
Bit 04, No error/error (no trip)
Bit 04=0: The frequency converter is not in fault mode.
Bit 04=1: The frequency converter shows an error but does
not trip.
Bit 05, Not used
Bit 05 is not used in the status word.
Bit 06, No error/triplock
Bit 06=0: The frequency converter is not in fault mode.
Bit 06=1: The frequency converter is tripped and locked.
Bit 07, No warning/warning
Bit 07=0: There are no warnings.
Bit 07=1: A warning has occurred.
