Licences
Using this application requires detailed knowledge and information about the system. The licence
key will not be given unless all necessary information has been given in advance to Vacon Finland for
approval.
This information includes:
-
The single line diagram of the system.
-
The voltage range.
-
The nominal power and short circuit current requirement.
-
The grid and load type (IT, three phase load and single phase load, direct on line motors).
-
The generators/motors, PTI or PTO, by-pass, battery backups, etc.
After the details have been approved by Vacon Finland, contact [email protected] to get
a document for the licence key approval. The licence key has to be approved by your contact person
in Vacon Finland.
Enclosure size FR4 will be operational in uGrid and Island mode without a licence key, but this
enclosure size is only for testing and demonstration purposes, not for real production.
Air and liquid-cooled drives that are compatible with AFE-II application ARFIFF05 or Grid Converter
application ARFIFF03 are the only ones that are supported. See details in the GTC Product
compatibility note, or for Air Cooled: Vacon NX AFE User Manual, and for Liquid Cooled: Vacon NXP
Liquid Cooled Drives User Manual.
Downloading AFE or uGrid application to products other than those listed are considered to be a
non-standard product the functionality of which has not been verified or documented. In such cases
the user takes full responsibility for possible hardware and software problems. Application support
is not available for non-standard products.

Compatibility issues in parameters between versions
NOTE! This application is not kept backwards compatible. See release notes and this chapter before
updating the application.
Update Note 1: When you update the application do not use NCDrive parameter download function.
Instead upload parameters from the unit and compare them to the old parameter file. The
application is constantly developed, and it includes changing parameter default values. If
parameters are directly downloaded to drive, improved default values will be lost.
Update Note 2: If OPT-D7 PI voltage control is needed in uGrid mode, do not use versions V082 or
V083.
