Our philosophy

As we have over 20 years of service experience, we know where to put the focus: As the connection between control and servo-motor the servo amplifier plays a central, important role in the coordination of tool machines or industrial robots. If it breaks down, the whole machine stands still. Now competent help is needed to reduce the down-time – a long waiting period is not acceptable.

We offer a short term repair service for damaged servo amplifiers to reduce your costs for machine down time. We are fast in finding the error, solve problems lastingly and work for moderate conditions. In most cases we do the repair in no longer than 48 hours.
