10 10  In order to be able to control each servo individually with commands, the first step should be to assign a different ID number to each servo (see details on the Configure ID, or "CID" command [[here>>doc:||anchor="HIdentificationNumber28ID29"]]). Only the servo(s) which have been configured to a specific ID will act on a command sent to that ID. There is currently no CRC or checksum implemented as part of the protocol.

If the LSS is ready for commands (initialized) it will respond to the query. A timeout between 50-100 ms is recommended to compensate for drivers, OS and buffering delays.

130 130  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 360.0 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 15335 (or 1533.5 degrees), taking the modulus would give 93.5 degrees (3600 * 4 + 935 = 15335) as the absolute position (assuming no origin offset).<div class="wikimodel-emptyline"></div>
