 In these scenarios, trapezoidal motion interpolation must be done by the framework, because the servos don't have time to act in a trapezoidal motion if they're being updated at such a high frame rate. In these scenarios, trapezoidal motion interpolation must be done by the framework, because the servos don't have time to act in a trapezoidal motion if they're being updated at such a high frame rate.

-The PID parameters for the servos can now be tuned individually for each joint, for a more elastic or firm response. By default they ship set to a firm and fast response.\\ +The PID parameters for the servos can now be individually tuned by the user on each joint (Servomotor), for a more elastic or firm response.

-The topic of PID tuning is an advanced one and we recommend that only advanced users attempt it. You should refer to the Control table of the actuators for information on PID tuning as these values are normally protected from change while in operation. T+The topic of PID tuning is an advanced one and we recommend that only advanced users attempt it.

 The whining noise that the actuators sometimes produced in the previous architecture is now much reduced. Oscillations are also much reduced which means control is now more precise and the overall feel is much improved.\\ The whining noise that the actuators sometimes produced in the previous architecture is now much reduced.

 Additionally energy loss through heat dissipation in the switching mechanism (at the motor MOSFETs)  has also been reduced, contributing to a longer lifespan, improved thermal behavior and overall improved power efficiency. Additionally energy loss through heat dissipation in the switching mechanism (at the motor MOSFETs)  has also been reduced, contributing to a longer lifespan, improved thermal behavior and overall improved power efficiency.
  
-In addition, a cooling fan is present on most models to further improve thermal behavior. The Fan speed multiplier can be adjusted by the user to for reduced sound impact or maximum thermal efficiency. (for Fan speed adjustments, refer to the [[eros:mainboard_ctltable|Main Board Control table]])+In addition, a cooling fan is present on most models to further improve thermal behavior.
