New inverter drive with built-in positioning

New inverter drive with built-in positioning

Achieving positioning in motor drive systems used to require a separate motion controller.   More recently servo drives have offered integrated positioning saving on purchase cost, installation time and panel space.  Now Lenze have brought to the market an inverter which has an integrated positioner as standard.  Whilst there are still some applications that need the precision and speed of servo technology, the majority of positioning demands can be achieved with a powerful inverter in combination with an asynchronous motor.  Therefore this new development offers machine builders a step reduction in cost from servo to inverter technology. 

The new 8400 HighLine frequency inverters, part of the Lenze L-force portfolio, feature point-to-point positioning as standard for up to 16 position destinations.  8400 HighLine offers all the cost savings expected from combining two drive elements – the motion controller and the frequency inverter – into one.  Purchase cost is reduced.  The machine is faster to build with less cabling and a smaller panel size.  Performance pushes into the area previously though of as servo with positioning accuracies possible of 0.1 to 0.2mm at 60 operations (120 movements) per second.  HighLine offers advanced features such as linear and S-shaped travel profiles, a touch probe function, homing selectable from 14 modes, and teaching of positions.
