The types of action commands which can be sent are described below, and they cannot be combined with other commands such as queries or configurations. Only one action command can be sent at a time. Action commands are session-specific, therefore once a servo is power cycled, it will not have any "memory" of previous actions or virtual positions (described below on this page). Action commands are sent serially to the servo's Rx pin and must be sent in the following format:

These configurations are retained in memory after the servo is reset or power is cut / lost. Some configuration commands affect the session, while others do not (see each command for details). Not all action commands have a corresponding configuration and vice versa. More information about which configuration commands are retained when in RC mode can be found on the [[LSS - RC PWM page>>doc:Lynxmotion Smart Servo (LSS).LSS - RC PWM.WebHome]]. Configuration commands are not cumulative, in that if two configurations are sent, one after the next, only the last configuration is used and stored. The format to send a configuration command is identical to that of an action command:

377 +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.
378 +
379 +A positive value of "angular stiffness":
380 +
381 +* The more torque will be applied to try to keep the desired position against external input / changes
382 +* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position
383 +
384 +A negative value on the other hand:
385 +
386 +* Causes a slower acceleration to the travel speed, and a slower deceleration
387 +* Allows the target position to deviate more from its position before additional torque is applied to bring it back
388 +
389 +The default value is zero and the effect becomes extreme by -4, +4. There are no units, only integers between -4 to 4. Greater values produce increasingly erratic behavior.
390 +
391 +Ex: #5AS-2<cr>

431 -When using the 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 (assuming the query is sent . 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.

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. The servo must be RESET or power cycled in order for the new ID to take effect.

Since smart servos are intended to be daisy chained, in order to respond to the same serial bus, all servos in a project should ideally be set to the same baud rate. Setting different baud rates will have the servos respond differently and may create issues. Available baud rates are: 9600 bps, 19200 bps, 38400 bps, 57600 bps, 115.2 kbps, 230.4 kbps, 250.0 kbps, 460.8 kbps, 500.0 kbps. Servos are shipped with a baud rate set to 9600. The baud rates are currently restricted to those above.

588 -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.
589 -
590 -A positive value of "angular stiffness":
591 -
592 -* The more torque will be applied to try to keep the desired position against external input / changes
593 -* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position
594 -
595 -A negative value on the other hand:
596 -
597 -* Causes a slower acceleration to the travel speed, and a slower deceleration
598 -* Allows the target position to deviate more from its position before additional torque is applied to bring it back
599 -
600 -The default value is zero and the effect becomes extreme by -4, +4. There are no units, only integers between -4 to 4. Greater values produce increasingly erratic behavior.

602 -Ex: #5AS-2<cr>

604 -This reduces the angular stiffness to -2 for that session, allowing the servo to deviate more around the desired position.
