Status Word According To Fc Profile (Stw) (Parameter 8-30 Protocol = Fc Profile) - Danfoss VLT Compressor Drive CDS 803 Design Manual

RS485 Installation and Set-...
Bit 09, Selection of ramp 1/2
Bit 09=0: Ramp 1 is active (parameter 3-41 Ramp 1 Ramp
Up Time to parameter 3-42 Ramp 1 Ramp Down Time).
Bit 09=1: Ramp 2 (parameter 3-51 Ramp 2 Ramp Up Time to
parameter 3-52 Ramp 2 Ramp Down Time) is active.
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. Turn off the control word
if not wanting to use it when updating or reading
parameters.
Bit 11, Relay 01
Bit 11=0: Relay not activated.
Bit 11=1: Relay 01 activated provided that [36] Control word
7 7
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 provided that [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 7.36.
Set-up
The function is only possible when [9] Multi Set-Ups is
selected in parameter 0-10 Active Set-up.
Make a selection in parameter 8-55 Set-up Select to define
how bit 13 gates with the corresponding function on the
digital inputs.
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, logic, or logic
and is selected.

Table 7.36 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
power supply (in case of external 24 V supply to controls).
Bit 01, Drive ready
Bit 01=0: The frequency converter is not ready.
Bit 01=1: The frequency converter is ready for operation,
but the coasting command is active via the digital inputs
or via serial communication.
Bit 02, Coasting stop
Bit 02=0: The frequency converter releases the compressor.
Bit 02=1: The frequency converter starts the compressor
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].
