Frequently asked questions (FAQ)

What are the most common problems with variable speed drives and soft starters?

Short circuits caused by contamination, for example, by corrosion, moisture or oil. Overheating and end of life are also common problems found in variable speed drives and soft starters.

Do you also install software (parameters/settings)?

You will receive up to 2 years warranty on our repairs, sales and exchanges. We will mention what warranty you will receive from us, per product and service.

Can you also transfer software from my old drive to a new one?

Yes, provided that the appropriate software is available to read the data from the item being repaired.

Will my drive be returned with the same programming?

We do our best to preserve your settings, but a defect can also cause these settings to be lost. Our advice is therefore that you always keep a backup.

How can I tell if a drive is defective?

A defective drive will occasionally shut down and may be difficult to start up again or perhaps not start up at all. Unexpected error messages may also be displayed.
