®
5000 INTERBUS
Status word under VLT standard
The status word is used for informing the master
(e.g. a PC) about the condition of the slave (VLT
5000 Series).

Bit 00, Control not ready/ready:
Bit 00 = "0" means that the frequency converter
has tripped.
Bit 00 = "1" means that the frequency converter
controls are ready, but that the power component is
not necessarily receiving any power supply (in case
of external 24 V supply to controls).
Bit 01, VLT not ready/ready:
Same meaning as bit 00; however, there is also a
supply to the mains component, and the frequency
converter is ready to run when it receives the
necessary start signals.
Bit 02, Coasting/enable:
Bit 02 = "0" means that the control word bit 03 is
"0" (Coasting) or that VLT 5000 Series has tripped.
Bit 02 = "1" means that control word bit 03 is "1"
and that VLT 5000 Series has not tripped.
Bit 03, No fault/trip:
Bit 03 = "0" means that VLT 5000 Series is not in a
fault condition. Bit 03 = "1" means that the VLT

Bit 10, Data not valid/valid:
Used for telling VLT 5000 whether the control word 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
possible to disconnect the control word if it is not to be
used in connection with updating or reading of
parameters.
Bit 11, Relay 01:
Bit 11 = "0": Relay 01 not activated. Bit 11 = 1:
Relay 01 activated, provided
Control word bit
has
been chosen in parameter 323.
Bit 12, Relay 04:
Bit 12 = "0": Relay 04 has not been activated. Bit
12 = "1": Relay 04 has been activated, provided
Control word bit
has been chosen in parameter 326.
NB!
Unless otherwise mentioned, the control
word bit is combined (gated) with the
corresponding function on the digital inputs
as a logic "or" function.
Bits 13/14, Choice of Setup:
Bits 13 and 14 are used for choosing 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
4
1
1
This function is only possible if
Multi-Setup
has been
selected in parameter 004.
NB!
Parameter 507 is used for choosing how bits 13/14
are to be combined (gated) with the corresponding
function on the digital inputs.
Bit 15, No function/reversing:
Reversing of the direction of rotation of the motor.
Bit 15 = "0" leads to no reversing, bit 15 = "1" leads
to reversing.
Please note that, in the factory setting, reversing
has been chosen as digital in parameter 506, which
means that bit 15 will only lead to reversing if
bus,
logic or
or
logic and
(however,
logic and
only
together with terminal 19) has been selected.
