Electronic cams provide exceptional dynamic performance
Lenze is now offering a facility for creating electronic cams with its 9400 servo drives, providing dynamic, precise and jerk-free motion. This has been developed by building on several years' experience with other servo controller series. However, by increasing the resolution from 16 to 24 bits per revolution, the 9400 offers significantly higher dynamic performance and accuracy.
Motion profiles are developed using the Cam Designer software tool, which is fully integrated within L-force Engineer. This brings clear advantages, including efficient and fast operation with a single engineering software package - which, in turn, reduces commissioning costs.
The advantage of motion control applications implemented in software is that sequences are easier to develop and optimise. The new cam facility supports limited, unlimited and modulo traversing ranges. Users can position drives on cams, carry out tool-to-material position trimming, or replace cams during an application cycle. In this way, drives can also be synchronised with external events.
With a keen eye on usability, Lenze has provided a comprehensive library of function blocks in L-force Engineer. This library can, for example, be used to create electronic couplings or cam groups, to perform mark synchronisation, or to compensate for downtime. The graphic user interface also simplifies signal flow planning.
One of the most powerful features of the 'Cam Designer' tool in L-force Engineer is that it can quickly provide an overview of the respective interactions with other axes. In contrast, conventional programming tools generally only provide a view of the individual drive. Another key advantage is that the entire project is available in L-force Engineer as a single file containing all data and settings. This is also integrated in the pluggable memory module of the 9400 servo drives, which provides additional insurance against mains failures.
