Fieldbus Profile; Control Word - Danfoss VLT 5000 Operating Instructions Manual

Fieldbus Profile

Control Word

Control Word as per Profidrive standard
(parameter 512 = Fieldbus Profile). The control word is
used for transmitting commands from a master (e.g.
a PC) to a slave (VLT frequency converter).

Bit 00, OFF1/ON1:
An ordinary ramp stop which uses the ramp time
in parameters 207/208 or 209/210. Bit 00 = "0"
leads to a stop and leads to output relay 01 or
04 being activated, the output frequency is 0 Hz,
provided Relay 123 has been selected in parameter
323 or 326. Bit 00 = "1" means that the adjustable
frequency drive will be able to start if the other
conditions for starting have been fulfilled.
Bit 01, OFF2/ON2:
Coasting stop. Bit 01 = "0" leads to a coasting stop and
leads to output relay 01 or 04 being activated, when the
output frequency is 0 Hz, provided Relay 123 has been
selected in parameter 323 or 326. Bit 01 = "1" means
that the adjustable frequency drive is able to start
provided the other conditions for starting are fulfilled.
Bit 02. OFF3/ON3:
Quick-stop, which uses the ramp time set in parameter
212. Bit 02 = "0" leads to a quick stop and leads
to output relay 01 or 04 being activated, when the
output frequency is 0 Hz, provided Relay 123 has been

selected in parameter 323 or 326. Bit 02 = "1" means
that the adjustable frequency drive is able to start,
provided the other conditions for starting are fulfilled.
Bit 03, Coasting/enable:
Coasting stop. Bit 03 = "0" leads to a stop. Bit 03 =
"1" means that the adjustable frequency drive is able
to stop, provided the other conditions for starting are
fulfilled. Note: in parameter 502 the choice is made
as to how bit 03 is to be combined (gated) with the
corresponding function in the digital inputs.
Bit 04, Quick-stop/ramp:
Quick-stop which uses the ramp time in parameter
212. Bit 04 = "0" leads to a quick- stop. Bit 04 =
"1" means that the adjustable frequency drive is able
to start, provided the other conditions for starting are
fulfilled. Note: In parameter 503 the choice is made
as to how dit o4 is to be combined (gated) with the
corresponding function on the digital inputs.
Bit 05, Freeze output frequency/ramp enable:
Bit 05 = "0" means that the given output frequency is
maintained even if the reference is changed. Bit 05 =
"1" means that the adjustable frequency drive is again
able to regulate, and the given reference is followed.
Bit 06, Ramp stop/start:
An ordinary ramp stop that uses the ramp time in
parameters 207/208 or 209/210; in addition, output
relay 01 or 04 will be activated when the output
frequency is ) Hz, provided Relay 123 has been
selected in parameter 323 or 326. Bit 06 = "0" leads
to a stop. Bit 06 = '1" means the adjustable frequency
drive is able to start, provided the other conditions for
starting are fulfilled. In parameter 505 the choice is
made as to how bit 06 is to be combined (gated) with
the corresponding function on the digital inputs.
Bit 07, No function/reset:
Reset of trip. Bit 07 = "0" means that there is no
reset. Bit 07 = "1" means that a trip is reset.
