Control Word/Status Word; Control Word According To Profidriveprofile - Danfoss VLT 5000 Operating Instructions Manual

Control word/Status word

The bits of the "Control word" tell the frequency
converter how to respond, while the status of the
bits in the "Status word" transmits information about
the frequency converter to the master.
One can select through parameter 512 whether
the Control word and Status word are to be
defined according to "Profidrive" (field bus) or
according to "FC Drive (Danfoss)". "FC Drive
(Danfoss)" is the factory setting.

Control word according to profidriveprofile

(Parameter 512 = field bus)
The Control word is used to send commands from
a master (e.g. a PC) to a slave.

NB!:
If "Fieldbus" has been selected, then a two-part
start command has to be observed when the
start is released (turn-on lock-out: bit 0).
For this it is necessary to first predetermine Hex 047E
and then Hex 047F in the Control word, for example.

Bit 00 OFF/ON 01:
Normal ramp stop using the ramp times of the
parameters 207/208 or 209/210.
Bit 00 = "0" leads to the stop and activation of the
output relay 01 or 04 if the output frequency is 0 Hz if
Relay 123 has been selected in parameter 323 or 326.
In the case of bit 00 = "1", the frequency converter can
start if the other start conditions are satisfied.
Bit 01, OFF 2/ON 2
Coasting stop
In the case of bit 01 = "0", a coasting stop and
activation of the output relay 01 or 04 occurs if
the output frequency is 0 Hz if Relay 123 has been
selected in parameter 323 or 326.
In the case of bit 01 = "1", the frequency converter can
start if the other start conditions are satisfied.
Bit 02, OFF 3/ON 3
Quick stop using the ramp time of parameter
212. In the case of bit 02 = "0", a quick stop and
activation of the output relay 01 or 04 occurs if
the output frequency is 0 Hz if Relay 123 has been
selected in parameter 323 or 326.
In the case of bit 02 = "1", the frequency converter can
start if the other start conditions are satisfied.
Bit 03, Coasting/No coasting
Coasting stop
Bit 03 = "0" leads to a stop.
In the case of bit 03 = "1", the frequency converter
can start if the other start conditions are satisfied.
Note: The selection in parameter 502 determines
how bit 03 is linked with the corresponding
function of the digital inputs.
