2. APPLICATION
SPECIFIC
2.1
High speed
The maximum frequency for the application is 7200 Hz (default is 50 Hz). The frequency is
displayed without decimal. However license code is needed to run above 1900 Hz.
The unit for the motor speed is either rpm or krpm depending on the selected Frequency Scale
(P2.1.17). The maximum frequency (7200Hz) is corresponding to the maximum nominal speed of
the motor of 432 000 rpm (1 pole pair).
2.1.1 7200Hz
By entering a licence code to parameter P2.9.14 is it possible to run over 1900 Hz.
This code is different for every drive and has to be ordered from Vacon. When ordering the drive
with this feature, the code will be calculated before delivery. If the user wants to activate the feature
afterwards, he has to inform Vacon about the
serial number of the power unit(s)
for the drive(s)
where the feature is wanted.
2.1.2 Fine
tuning
It is possible to tune the motor controller for smoother run, especially in high-speed mode, and for
PMS motors
See parameter group 9.
And separate parameters: 2.1.17, 2.1.18, 2.4.14, 2.4.15, 2.4.16, 2.6.14,
2.1.3 Trial
Time
It is possible to run the drive over 1900Hz, without license key, for 2 weeks. When these 2 weeks
has expired will the drive trip and it is not longer possible to run the drive over 1900Hz. Time left can
be see from monitoring variable V1.17 Trial Time Left. When in Trial Time mode, the drive will give
warning message each time the start command is given.
2.2
Long ramp times
By setting parameter P.2.1.16, Long Ramps, to YES, is it possible to set the acceleration and
deceleration -times between 1-30 000s (8h 20min) with one-second resolution.
If No is selected (default) is the max acceleration/deceleration time 0,1-3000s.
2.3
Fieldbus
In this application is it also possible to separately program the ProcessData Output 1-8 for the
fieldbus. This is done by setting the ID number of the parameter or value that you want to monitor to
Process Data Ouput 1-8.
See parameter group 10
