VLT® 5000/ 5000 FLUX/ 6000 HVAC/
8000 AQUA PROFIBUS
Each PCD is defined as a word. If data should be
read from a parameter that has an attribute of Integer
32 or Unsigned 32 the parameter should be defined
twice in the following PCD
’
s: PCD 3 and 4, PCD 5
and 6, PCD 7 and 8 or PCD 9 and 10.
NB!:
Note: The odd subindex must be written
first. Otherwise the data will be interpreted
as 2 low words.1
Example PPO type 6:
PCD 1
CTW/STW
PCD 2
MRV/MAV
PCD 3
Par. 515
PCD 4
Par. 518
PCD 5
Par. 520
High word
PCD 6
Par. 520
Low word
PCD 7
Par. 538
High word
PCD 8
Par. 538
Low word
CTW/STW = Control word / Status word = 16 bit
MRV/MAV = Main Reference Value / Main
Actual Value = 16 bit
Par 515 Data readout: Reference % =
Datatype 3
⇒
Integer 16
Par 518 data readout: Frequency = Datatype
3
⇒
Integer 16
Par 520 Data readout= Motor current =Datatype
7
⇒
Unsigned 32
Par 538 Data readout: Alarm Word = Datatype
7
⇒
Unsigned 32
917 Spontaneous/event messages
(SPONT. MESSAGE)
Value:
✭
Off (OFF)
[0]
On (ON)
[1]
Function:
The spontaneous and event messages may be
switched if the frequency converter is to report a
message in the event of a warning or alarm status. A
description of the spontaneous and event messages
can be found in section
PCA processing
.
Description of choice:
- OFF: The frequency converter does not
report a spontaneous or event message in the
warning or alarm status.
- ON: When PPOs are, the frequency converter
reports a spontaneous message in the event
of a warning or alarm status.
918 Station address
(STATION ADDR)
Value:
0 -125
✭
126
Function:
All stations connected to the same bus must
have a unique address. The station address
can be set in parameter 918.
NB!:
A change in parameter 918 is executed
at next power up or if parameter 800 is
updated. Please see section Station address
in this manual for further information.
927 PCV operating authority
(PARAMETER EDIT)
Value:
Disable
[0]
✭
Enable
[1]
Function:
The parameter channel PCV can be blocked so
that the modification of parameters through this
channel is not possible. Access through the standard
RS 485 interface is still possible.
NB!:
When parameters 927 and 928 are deactivated,
the "Warning 34" in the display of the frequency
converter will also be suppressed.
Description of choice:
- Disable: Parameter processing through the
PROFIBUS is not active.
- Enable: Parameter processing through the
PROFIBUS is active.
928 Control authority
(PROCESS CONTROL)
Value:
Disable
[0]
✭
Enable
[1]
Function:
The process control (adjustment of Control word speed
reference value and of the following variable PCD) can
be blocked. Control through the control card terminals
is still possible via the terminals, depending on how
the parameters 502-508 have been programmed.
