96 -The ability to store a "virtual angular position" is a feature which allows for rotation beyond 360 degrees, permitting multiple rotations of the output horn, moving the center position and more. The "absolute position" would be the angle of the output shaft with respect to a 360.00 degree circle and can be obtained by taking the modulus (with respect to 360 degrees) of the value. For example if the virtual position is reported as 153350 (or 1533.50 degrees), taking the modulus would give 93.5 degrees (36000 * 4 + 9350 = 153350) as the absolute position (assuming no origin offset).

268 +A servo's identification number cannot be set "on the fly" and must be configured via the CID command described below. The factory default ID number for all servos is 0. Since smart servos are intended to be daisy chained, in order to respond differently from one another, the user must set different identification numbers.

274 +When using the broadcast query ID command, it is best to only have one servo connected and thus receive only one reply. This is useful when you are not sure of the servo's ID, but don't want to change it. Using the broadcast command (ID 254) with only one servo will have that servo reply with its ID number. Alternatively, pushing the button upon startup and temporarily setting the servo ID to 255 will still result in the servo responding with its "real" ID.<div class="wikimodel-emptyline"></div>

280 +Setting a servo's ID in EEPROM is done via the CID command. All servos connected to the same serial bus that have will be assigned that ID. In most situations each servo must be set a unique ID, which means each servo must be connected individually to the serial bus and receive a unique CID number. It is best to do this before the servos are added to an assembly. Numbered stickers are provided to distinguish each servo after their ID is set, though you are free to use whatever alternative method you like.

507 +EM1 (Enable Motion Profile #1) is the default mode of the LSS and is an easy way to control the servo's position with a single (serial) position command. This mode uses a trapezoidal motion profile which takes care of acceleration, constant speed travel and deceleration. Once the actual position is within a certain value of the target, it switches to a holding algorithm. The LSS commands for Angular Acceleration and Deceleration (AA/CAA/AD/CAD) Angular Stiffness (AS/CAS) and Angular holding stiffness (AH/CAH) affect this motion profile. Modifiers like SD/S and T can be used in EM1.<div class="wikimodel-emptyline"></div>

515 +This command will disable the built-in trapezoidal motion profile. As such, the servo will move at full speed to the target position using the D/MD action commands. Modifiers like SD/S or T cannot be used in EM0 mode. By default the Filter Position Counter, or "FPC" is active in EM0 mode to smooth out its operation. EM0 is suggested for applications where an external controller will be determining all incremental intermediate positions of the servo's motion, effectively replacing a trajectory manager. To prevent having to send position commands continuously to reach the desired position in EM0/FPC active (FPC >= 2), an internal position engine (IPE) repeats the last position command. Note that in EM0 mode, the servo will effectively always be in status: Holding (if using the query status command).

616 +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.<div class="wikimodel-emptyline"></div>
348 348  
618 +A higher value of "angular stiffness":<div class="wikimodel-emptyline"></div>
619 +

621 +* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position<div class="wikimodel-emptyline"></div>
622 +
623 +A lower value on the other hand:<div class="wikimodel-emptyline"></div>

626 +* Allows the target position to deviate more from its position before additional torque is applied to bring it back<div class="wikimodel-emptyline"></div>
627 +
628 +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.<div class="wikimodel-emptyline"></div>

808 +Ex: #5SR45&lt;cr&gt;<div class="wikimodel-emptyline"></div>
809 +This command sets the servo's maximum speed for motion commands in rpm for that session. In the example above, the servo's maximum speed for that session would be set to 45rpm. The servo's maximum speed cannot be set higher than its physical limit at a given voltage. SR overrides CSR (described below) for that session. Upon reset or power cycle, the servo reverts to the value associated with CSR as described below. Note that SD (described above) and SR are effectively the same, but allow the user to specify the speed in either unit. The last command (either SR or SD) received is what the servo uses for that session.<div class="wikimodel-emptyline"></div>

815 +By default QSR will return the current session value, which is set to the value of CSR as reset/power cycle and changed whenever an SD/SR command is processed. If #5QSR1&lt;cr&gt; is sent, the configured maximum speed (CSR value) will be returned instead. You can also query the current speed using "2" and the current target travel speed using "3".
