Parameter
Handling
Bit 12 = "1": Relay 2 is activated, provided
Control word bits 11/12 has been selected in
parameter 326 Relay outputs.
NB!:
If the time-out period set in parameter 556
Bus time interval function is exceeded, relays
1 and 2 will lose their voltage if they have
been activated via serial communication.
B
its 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
100
201
310
411
This function is only possible if Multi-setups has
been selected in parameter 0
04.
Note: In parameter 507 Choice of Setup achoiceis
made of the way bits 13/14 are to be gated with the
corresponding function of
the digital inputs.
B
it 15, No function/re
versing:
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 digit
al in parameter 506 Reversing,
which means that bit 15 only leads to reversing, if
bus, logic or orlogic and has been selected (however,
logic and only to
gether with terminal 19).
■ Status Word Bi
t Descriptions VLT 6000 / VLT 8000
The status word is used to inform the master
(e.g. a PC) of the condition of the slave (VLT
6000 HVAC / VL
T 8000 AQUA).

Bit 00, Control ready:
Bit 00 = "1". The frequency converter is
ready for operation.
Bit 00 = "0". The frequency converter has tripped.
B
it 01, Drive ready:
Bit 01 = "1". The frequency converter is ready for
operation, but terminal 27 is a logic ’0’ and/or a coasting
command has been received via serial communication.
B
it 02, Stand by:
Bit 02 = "1". The frequency converter is able to start
the motor when a start command is given.
B
it 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.
B
it 04, Not in use:
Bit 04 is not used in the status word.
B
it 05, Not in use:
Bit 05 is not used in the status word.
B
it 06, Trip lock:
Bit 06: "1" means that there is a trip lock.
B
it 07, No warning/warning:
Bit 07 = "0" means there is no warning.
Bit 07 = "1" means a warning has occurred.
NB!:
All warnings are described in the Operating
Instructions.
B
it 08, Speed ≠ref./speed = ref.:
Bit 08 = "0" means that the motor is running, but
that the present speed is different from the preset
