KVAL, a highly specialized manufacturer of door cutting machinery was searching for a better servo drive to improve the cost and performance of its milling machines.
A local automation distributor introduced them to the Lenze Americas PositionServo.
The challenge finding a cost competitive drive that would fit the existing profile and yet work with legacy servomotors and resolver feedback. The solution was found in the PositionServo 941 designed specifically for resolver feedback. The PositionServo 941 was fitted directly to an existing machine and tested immediately in 'torque mode'. The drive performed beautifully from the first application of power and led to substantial orders soon after.
KVAL is recognized as a leader in the design and manufacturing of precision engineered door machining and millwork equipment. Increased competitiveness within the millwork industry has forced many smaller companies to become more specialized. As a result, KVAL had to alter the design and configuration of many of its machines, the ease-of-use and programming of the PositionServo 941 meant that it was a simple solution for varying machine requirements.
Compatibility with the existing machine set-up was very important and since Lenze Americas PositionServo products are designed to work effectively with the widest range of motors, feedback and machine control systems, it was no problem to fit in with components from three other manufacturers.
Cost is an inevitable pressure for any machine manufacturer and KVAL is no different, the fact that the PositionServo provides solid precision performance, but without a price premium sealed the deal.

AC Tech Drives
With its Price, flexibility and power range now extended to reach 30 Hp, the SMVector drive excels in traditional VFD applications as well as in environments where inverter technology was once considered too costly. Lenze AC Tech describes the drive's increased capabilities as including an additional programmable digital input, terminals for RS-485 communications and an enhanced keypad.
The Brake Casing is encapsulated or suitable for tachometer mounting. In azimuth drives, brakes from our modular BFK458 series are used. They keep the turbine aligned in the wind. In the event of a fault, the brakes have to act as a friction clutch to enable the gondola to move with the wind. In the offshore area, the requirements for corrosion protection and robustness are very high. Encapsulated version with special surface protection
