Parameter sets
Section 7-1
Select and copy parameter set
The parameter set selection is done in menu [241], Select Set. First select the
main set in menu [241], normally A. Adjust all settings for the application. Usu-
ally most parameters are common and therefore it saves a lot of work by copy-
ing 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 complete contents of a sin-
gle 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
18.
Activate the parameter changes via digital input by setting menu [241], Select
Set to DigIn.
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.
Examples
Different parameter sets can be used to easily change the setup of a VSD to
adapt quickly to different application 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 available. 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 5 digital inputs: DigIn1, 2 and 3 for selecting preset
reference within one parameter set and DigIn 4 and DigIn 5 for selecting the
parameter sets.
Bottling machine with 3 different products
Use 3 parameter sets for 3 different Jog reference speeds when the machine
needs to be set up. The 4th parameter set can be used for “normal” remote
control when the machine is running at full production.
Product changing on winding machines
If a machine has to change between 2 or 3 different products e.g. winding
machine with different gauges of thread, it is important that acceleration,
deceleration times, Max Speed and Max Torque are adapted. For each thread
size a different parameter set can be used.
