Description of the selection
The sequence of the subindices corresponds to
the sequence of the PCD in the PPO, i.e. subindex
1 ≈ PCD 1, subindex 2 ≈ PCD 2 etc. Each subindex
may contain the number of any VLT parameter.
However, only 2-byte values (bytes with the lowest
weight) can be written to parameters with 4-byte
data values, since 1 PCD consists of only 2 bytes.
917 Spontaneous/event messages
(SPONT. MESSAGE)
Value
Off (OFF)
On (ON)
Function
The spontaneous and event messages may be
switched if the VLT 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 on page 17.
Description of the selection
– OFF: The VLT does not report a spontaneous or
event message in the warning or alarm status.
– ON: When PPOs are used (DP or FMS), the VLT
reports a spontaneous message in the event of
a warning or alarm status. When FMS is used
without PPOs, the VLT reports an event message
in the event of a warning or alarm status.
918 User address (STATION ADDRESS)
Value
1-126
Function
Every station connected to the same bus must
have an unambiguous address. The station
address can be set in parameter 918 or by means
of a hardware switch, see page 10. The address
can only be set in parameter 918 if the hardware
switch is set to 0 or > 126. If the setting of the
hardware switch is ≠ 0, the parameter will indicate
the current setting of the switch. During an update
of parameter 800 or during the next turn-on proce-
dure, the parameter 918 changes too.

VLT ® 5000/5000 Flux/6000 HVAC/8000 AQUA PROFIBUS
927 PCV operating authority
Value
Without PROFIBUS
With PROFIBUS
Function
The parameter channel PCV may be blocked so
that the modification of parameters through this
channel is not possible. Access through the stan-
dard RS 485 interface is still possible.
[0]
[1]
Description of the selection
– Without PROFIBUS: Parameter processing
through the PROFIBUS is not active.
– With PROFIBUS: Parameter processing through
the PROFIBUS is active.
9 2 8 Control authority (PROCESS CONTROL)
Value
Without PROFIBUS
With PROFIBUS
Function
The process control (adjustment of control word
and speed reference value and of the following
variable PCD) can be blocked. Control through the
control card terminals is still possible via the termi-
nals, depending on how the parameters 502-508
have been set. Access through the standard
RS 485 is also still possible.
0
Description of the selection
– Without PROFIBUS: Process control through the
PROFIBUS is not active.
– With PROFIBUS: Process control through the
PROFIBUS is active.
(PARAMETER EDIT)
When parameters 927 and 928 are deactiva-
ted, the "Warning 34" in the display of the
VLT will also be suppressed.
When parameters 927 and 928 are deactiva-
ted, the "Warning 34" in the display of the
VLT will also be suppressed.
The motor may start without advance war-
ning when parameter 928 is being changed
and start commands are present.
