Parameters; Vlt Frequency Converter Parameters - Danfoss VLT 5000 Operating Instructions Manual

VLT frequency converter parameters

Only the parametergroups (800 and 900) specific to
the profibus are described in this manual. For any
other parameters of the VLT 5000 series/VLT 5000
Flux, VLT 6000 HVAC/VLT 8000 AQUA and their
functions, please refer to the VLT 5000/5000 Flux/6000
HVAC/8000 AQUA series operations manual.
NB!:
Please pay special attention to the following
parameters which are not described
in this manual:
002: In the case of local operation, a control
via PROFIBUS is not possible.
502-508: Selection of how the PROFIBUS
control commands are to be linked
with the control commands of the
digital inputs of the control card.
512: Control word profile, selection of a
Control word according to FIELDBUS
or according to a Control word
specified by Danfoss.
515-538: Data output parameters which can
be used for the display of a variety
of current data of the frequency
converter, e.g. current status of the
analog and digital inputs of the control
card and, therefore, their usage as
inputs for the master.
800 Protocol selsction
(PROTOCOL SELECT)
Value:
Read only
Function:
Selection of the PROFIBUS protocol supported
by the master
Description of choice:
DP: Communication according to EN 50170, part 3
NB!:
In the event of an update of parameter
800, from LCP or FC bus even with an
unchanged data value, the PROFIBUS option
is initialized, which means that all communication
parameters, e.g. slave address, are being updated.
The communication is being reset and the previous
changed address parameter 918 will be valid.

803 Time after bus error
(BUS TIME OUT)
Value:
1 - 99 sec.
804 Response after bus error
(TIME OUT FUNCT.)
Value:
Off (OFF)
Freeze output frequency (FREEZE OUTPUT)
Stop with auto restart (STOP)
Output frequency = JOG frequency (JOGGING)
Output freq. = Max. freq. (MAX SPEED)
Stop with trip (STOP AND TRIP)
Control without PROFIBUS
(NO COM OPT CONTROL)
Select setup 4 (SELECT SETUP 4)
Select setup 2 (SELECT SETUP 2)
Function:
The timeout counter is activated at the first receipt
of a valid Control word, i.e. bit 10 = OK. In case
of an acyclic DP V1 communication the timeout
function will not be triggered.
The Timeout function can be activated in two ways:
1. CTW is not updated within the specified time.
2. Parameter 805 = "Bit 10 = 0 Þ Timeout"
and bit 10 = "0".
The frequency converter remains in the timeout status
until one of the following four conditions occurs.
1. A valid Control word (bit 10 = OK) is received and
a reset (bus, terminals or control panel) is activated
(reset is only necessary if the timeout function Stop
with trip was selected) ⇒ control via PROFIBUS is
resumed with the current Control word.
2. Parameter 002 = Local operation
through control panel is active.
3. Parameter 928 = Not active
through terminals and RS 485 is active.
NB!:
The timeout counter is reset and needs to
be triggered by a valid Control word before
a new timeout can be activated.
4. Parameter 804 = Off ⇒
resumed, with the Control word used last being taken.
Description of choice:
- Save output frequency: Save ('freeze') the output
frequency until communication resumes.
