As servo drive technology evolves, manufacturers face inevitable product lifecycle changes that require proactive evaluation of aging motion control systems before replacement parts become scarce and ...

The method involves changing the triple-loop cascade control to a dual-loop control architecture with an integrated outer loop for position and speed control and an inner loop for current control.

Figure 2: By using smaller servo drives, robots have less dead weight to deal with, reducing their wear-and-tear. The ongoing trend of micro-sized servo drive technology is driven by Moore’s Law and ...
