Direct is simply more dynamic

Positioning tasks increasingly require short positioning cycles and high precision. The CDD3000 system for direct drives can be used here: Handling tasks today require extremely short positioning cycles and the entire production process depends on high-precision positioning. Reasonably cost gear solutions are subject to a number of restrictions in terms of elasticity, backlash and wear. The mechanical coupling of the drive is often the critical factor, such as the gears, clutches, shafts or belts used exhibit slack or elasticity, and thus limit the dynamic bandwidth of the controller. For these tasks there is now a "direct" solution from LTi. The CDD3000 system (servo controller plus torque motor or linear motor) is very dynamic and allows coupling of the load.

High Torque Motors:

• Dynamic and precise positioning, rotation

• Mainly high pole

• Low cost

Linear motors:

• Dynamic and precise positioning, linear

• Very dynamic with an iron-free structure

• Powerful with iron core structure

Special functions for direct drive technology

• Switch detection, including standstill braking

• Compensation of detent and friction torques

• Removal of mechanical natural frequencies through the use of a notch filter

• Precontrol up to the current regulator

• GPOC - to compensate for encoder measurement Errors

• Special software for direct drive elevators

Linear motors are very simple in design, as they have no mechanical transmission elements from rotational to linear motion. Disadvantages such as friction, backlash, elasticity and wear are eliminated, and the linear motor solution also offers the advantages of low inertia and low noise. This means you can take advantage of pre-assembled linear motor units. It is also no longer necessary to select components from separate vendors and then have to match them.
