Angular Stiffness (**AS**)__ ====== 592 - 593 -The servo's rigidity / angular stiffness can be thought of as (though not identical to) a damped spring in which the value affects the stiffness and embodies how much, and how quickly the servo tried keep the requested position against changes. There are no units. 594 - 595 -A positive value of "angular stiffness": 596 - 597 -* The more torque will be applied to try to keep the desired position against external input / changes 598 -* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position 599 - 600 -A negative value on the other hand: 601 - 602 -* Causes a slower acceleration to the travel speed, and a slower deceleration 603 -* Allows the target position to deviate more from its position before additional torque is applied to bring it back 604 - 605 -The default value for stiffness depending on the firmware may be 0 or 1. Greater values produce increasingly erratic behavior and the effect becomes extreme below -4 and above +4. Maximum values are -10 to +10. 606 - 607 -Ex: #5AS-2<cr> 608 - 609 -This reduces the angular stiffness to -2 for that session, allowing the servo to deviate more around the desired position. This can be beneficial in many situations such as impacts (legged robots) where more of a "spring" effect is desired. Upon reset, the servo will use the value stored in memory, based on the last configuration command. 610 - 611 -Ex: #5QAS<cr> 612 - 613 -Queries the value being used. 614 - 615 -Ex: #5CAS<cr> 616 - 617 -Writes the desired angular stiffness value to memory. 618 - 619 -====== __A2. Angular Holding Stiffness (**AH**)__ ====== 620 - 621 -The angular holding stiffness determines the servo's ability to hold a desired position under load.

Configure LED Blinking (**CLB**)__ ====== 652 - 653 -This command allows you to control when the RGB LED will blink the user set color (see [[16. RGB LED>>||anchor="H16.RGBLED28LED29"]] for details). This is very useful when visually seeing what the servo is doing. You can turn on or off blinking for various LSS status.
