Danfoss VLT Compressor Drive CDS 803 - Status Word According to FC Profile (STW) (Parameter 8-30 Protocol = FC Profile)

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 o 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
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 Bit 13
1 0
2 1
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 dene
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 Prole
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].
