Danfoss VLT 6000 HVAC Series User Manual

Used for telling the frequency converter whether the
control is to be used or ignored. Bit 10 = "0" means that
the control word is ignored. Bit 10 = "1" means that the
control word is used. This function is relevant because
the control word is always contained in the telegram,
regardless of the type of telegram used, i.e. it is pos-
sible to disconnect the control word if it is not to be
used in connection with updating or reading of param-
eters.
Bit 11, Relay 1:
Bit 11 = "0": Relay 1 is not activated.
Bit 11 = "1": Relay 1 is activated, provided Control word
bits 11/12 has been selected in parameter 323 Relay
outputs.
Bit 12, Relay 2:
Bit 12 = "0": Relay 2 is not activated.
Bit 12 = "1": Relay 2 is activated, provided Control word
bits 11/12has been selected in parameter 326 Relay
outputs.
NB!
If the time-out period set in parameter 556
Bus time interval function is exceeded, re-
lays 1 and 2 will lose their voltage if they
have been activated via serial communi-
cation.
Bits 13/14, Choice of Setup:
Bits 13 and 14 are used to choose among the four
menu Setups in accordance with the following table:
Setup
Bit 14 Bit 13
1 0 0
2 0 1
3 1 0
411
This function is only possible if Multi-setups has been
selected in parameter 004.
Note: In parameter 507 Choice of Setup a choice is
made of the way bits 13/14 are to be gated with the
corresponding function of the digital inputs.
Bit 15, No function/reversing:
Bit 15 = "0" leads to no reversing.
Bit 15 = "1" leads to reversing.
Please note that, in the factory setting, reversing has
been selected as digital in parameter 506 Reversing,
which means that bit 15 only leads to reversing, if bus,
logic or orlogic and has been selected (however, log-
ic and only together with terminal 19).
Status word as per FC protocol
The status word is used to inform the master (e.g. a
PC) of the condition of the slave (VLT 6000 HVAC).

Bit 00, Control ready:
Bit 00 = "1". The frequency converter is ready for op-
eration.
Bit 00 = "0". The frequency converter has tripped.
Bit 01, Drive ready:
Bit 01 = "1". The frequency converter is ready for op-
eration, but terminal 27 is a logic '0' and/or a coasting
command has been received via serial communica-
tion.
Bit 02, Stand by:
Bit 02 = "1". The frequency converter is able to start
the motor when a start command is given.
Bit 03, No trip/trip:
Bit 03 = "0" means that the VLT 6000 HVAC is not in
an error state. Bit 03 = "1" means that the VLT 6000
HVAC has tripped and needs a reset signal in order for
operation to be resumed.
Bit 04, Not in use:
Bit 04 is not used in the status word.
Bit 05, Not in use:
Bit 05 is not used in the status word.
Bit 06, Trip lock:
Bit 06: “1” means that there is a trip lock.
Bit 07, No warning/warning:
