The definition of smart servo on this site must include the following functions :
- Motor Drive (Drive): Traditional servo drive features focus on high response and stability and are easy to use.
- Motion Control (Motion): Command planning, such as point-to-point, line/circular interpolation or e-cam, PID …
- Development Environment(Platform): Programmable to flexibly use the above functions to meet the ever-changing application
In short, smart servo is a traditional (pure) servo drive that contains a motion controller. The motion functions provided can be complex or just simple point-to-point commands. The way of programming can use instructions, or other simpler editing methods.
The advantages of smart servo :
As the computing power of the DSP becomes more and more powerful, it is easier to build a motion controller in the drive. It can provide not only simple motion functions but also the function of high-end motion controllers. In addition, because the motion controller and servo drive are integrated in one system, the transmission delay and bandwidth limitation of the communication network disappear ! Therefore, the architectural advantages of intelligent servo are more significant, as listed below :
- Good Real-time performance : No communication delay, no bandwidth limit
- Resource integration : multi-axis information exchange is easy
- Scalable : system performance is not affected by increased number of axes
- Flexibility : can be customized according to different needs
- Others : Cost savings, anti-noise interference, simplified wiring
Suitable for smart servo usage :
- High Real-time requirements, such as PID applications
- Low number of axes but high-end motion functions are required. It is too expensive to use the motion controller.
- Customized requirements or system upgrades, existing controllers have been unable to modify.
- Large noise, serious interference occasions
- Limited installation space
