7. Main Features
This chapter contains descriptions of the main features
of the VSD.
7.1 Parameter sets
Parameter sets are used if an application requires dif-
ferent settings for different modes. For example, a
machine can be used for producing different products
and thus requires two or more maximum speeds and
acceleration/deceleration times. With the four parame-
ter sets different control options can be configured with
respect to quickly changing the behaviour of the VSD. It
is possible to adapt the VSD online to altered machine
behaviour. This is based on the fact that at any desired
moment any one of the four parameter sets can be acti-
vated during Run or Stop, via the digital inputs or the
control panel and menu [241].
Each parameter set can be selected externally via a dig-
ital input. Parameter sets can be changed during opera-
tion and stored in the control panel
.
Define parameter sets
When using parameter sets you first decide how to
select different parameter sets. The parameter sets
can be selected via the control panel, via digital inputs
or via serial communication. All digital inputs and vir-
tual inputs can be configured to select parameter set.
The function of the digital inputs is defined in the menu
[520].
Fig. 37 shows the way the parameter sets are activated
via any digital input configured to Set Ctrl 1 or Set Ctrl
2.
Fig. 37 Selecting the parameter sets
Select and copy parameter set
The parameter set selection is done in menu [241],
Select Set. First select the main set in menu [241], nor-
mally A. Adjust all settings for the application. Usually
most parameters are common and therefore it saves a
lot of work by copying set A>B in menu [242]. When
parameter set A is copied to set B you only change the
parameters in the set that need to be changed. Repeat
for C and D if used.
With menu [242], Copy Set, it is easy to copy the com-
plete contents of a single parameter set to another
parameter set. If, for example, the parameter sets are
selected via digital inputs, DigIn 3 is set to Set Ctrl 1 in
menu [523] and DigIn 4 is set to Set Ctrl 2 in menu
[524], they are activated as in Table 17.
Activate the parameter changes via digital input by set-
ting menu [241], Select Set to DigIn.
Examples
Different parameter sets can be used to easily change
the setup of a VSD to adapt quickly to different applica-
tion requirements. For example when
• a process needs optimized settings in different
stages of the process, to
- increase the process quality
- increase control accuracy
- lower maintenance costs
- increase operator safety
With these settings a large number of options are avail-
able. Some ideas are given here:
Multi frequency selection
Within a single parameter set the 7 preset references
can be selected via the digital inputs. In combination
with the parameter sets, 28 preset references can be
selected using all 4 digital inputs: DigIn1, 2 and 3 for
selecting preset reference within one parameter set
NOTE: The only data not included in the parameter set is
Motor data 1-4, (entered separately), language,
communication settings, selected set, local remote, and
keyboard locked.

NOTE: The selection via the digital inputs is immediately
activated. The new parameter settings will be activated
on-line, also during Run.
NOTE: The default parameter set is parameter set A.
