527 -If a safety limit has been reached and exceeded, the LED will flash red and the servo will stop providing torque (no longer react to commands which cause the motor to rotate). In order to determine which limit has been reached, send a Q1 command. The servo must be RESET in order to return to normal operation, though if a limit is still detected (for example the servo is still too hot), it will revert back to Safe Mode.
509 +"Gyre" is defined as a circular course or motion. The effect of changing the gyre direction is as if you were to use a mirror image of a circle. CW = 1; CCW = -1. The factory default is clockwise (CW).

539 -The number returned has one decimal, so in the case above, servo with ID 5 has an input voltage of 11.2V (perhaps a three cell LiPo battery).
517 +The value returned above means the servo is in a counter-clockwise gyration.

545 -The units are in tenths of degrees Celcius, so in the example above, the servo's internal temperature is 56.4 degrees C. To convert from degrees Celcius to degrees Farenheit, multiply by 1.8 and add 32. Therefore 56.4C = 133.52F.
523 +This changes the gyre direction as described above and also writes to EEPROM.

548 548  
549 -Ex: #5QC<cr> might return *5QC140<cr>
527 +In certain cases, a user might want to have the servo move to a specific angle upon power up. We refer to this as "first position". The factory default has no first position value stored in EEPROM and therefore upon power up, the servo remains limp until a position (or hold command) is assigned. FP and FD are different in that FP is used for RC mode only, whereas FD is used for smart mode only.
550 550  
551 -The units are in milliamps, so in the example above, the servo is consuming 140mA, or 0.14A.

531 +Ex: #5QFP<cr> might return *5QFP1550<cr>
554 554  
555 -This command puts the servo into RC mode (position or continuous), where it will only respond to RC pulses. Note that because this is the case, the servo will no longer accept serial commands. The servo can be placed back into smart mode by using the button menu.
533 +The reply above indicates that servo with ID 5 has a first position pulse of 1550 microseconds. If no first position has been set, servo will respond with DIS ("disabled").

561 561  
562 -EX: #5CRC2<cr>
537 +Ex: #5CP1550<cr>
563 563  
564 -This command would place the servo in RC wheel mode after a RESET or power cycle. Note that after a RESET or power cycle, the servo will be in RC mode and will not reply to serial commands. Using the command #5CRC<cr> or #5CRC3<cr> which requests that the servo remain in serial mode still requires a RESET command.
539 +This configuration command means the servo, when set to RC mode, will immediately move to an angle equivalent to having received an RC pulse of 1550 microseconds upon power up. Sending a CFP command without a number results in the servo remaining limp upon power up (i.e. disabled).
565 565  
566 -Important note:** **To revert from RC mode back to serial mode, the [[LSS - Button Menu>>doc:lynxmotion-smart-servo.lss-button-menu.WebHome]] is required. Should the button be inaccessible (or broken) when the servo is in RC mode and the user needs to change to serial mode, a 5V constant HIGH needs to be sent to the servo's Rx pin (RC PWM pin), ensuring a common GND and wait for 30 seconds. Normal RC PWM pulses should not exceed 2500 milliseconds. After 30 seconds, the servo will interpret this as a desired mode change and change to serial mode. This has been implemented as a fail safe.
541 +====== __21. First / Initial Position (Degrees)__ ======
567 567  
568 -====== __28. **RESET**__ ======
543 +In certain cases, a user might want to have the servo move to a specific angle upon power up. We refer to this as "first position". The factory default has no first position value stored in EEPROM and therefore upon power up, the servo remains limp until a position (or hold command) is assigned.

551 +Configure First Position in Degrees (**CFD**)
577 577  
578 -This command sets in motion the reset of all values to the default values included with the version of the firmware installed on that servo. The servo then waits for the CONFIRM command. Any other command received will cause the servo to exit the DEFAULT function.
553 +Ex: #5CD64<cr>
579 579  
580 -EX: #5DEFAULT<cr> followed by #5CONFIRM<cr>
555 +This configuration command means the servo, when set to smart mode, will immediately move to 6.4 degrees upon power up. Sending a CFD command without a number results in the servo remaining limp upon power up.
581 581  
582 -Since it it not common to have to restore all configurations, a confirmation command is needed after a firmware command is sent. Should any command other than CONFIRM be received by the servo after the firmware command has been received, it will exit the command.
557 +====== __22. Query Target Position in Degrees (**QDT**)__ ======
583 583  
584 -Note that after the CONFIRM command is sent, the servo will automatically perform a RESET.

585 585  
586 -====== __30. **UPDATE** & CONFIRM__ ======
561 +The query target position command returns the target angle during and after an action which results in a rotation of the servo horn. In the example above, the servo is rotating to a virtual position of 678.3 degrees. Should the servo not have a target position or be in wheel mode, it will respond without a number (Ex: *5QDT<cr>).
587 587  
588 -Ex: #5UPDATE<cr>
563 +====== __23. Query Model String (**QMS**)__ ======
589 589  
590 -This command sets in motion the equivalent of a long button press when the servo is not powered in order to enter firmware update mode. This is useful should the button be broken or inaccessible. The servo then waits for the CONFIRM command. Any other command received will cause the servo to exit the UPDATE function.

573 +This reply means the servo model is 0xFFF000000 or 100, meaning a high speed servo, first revision.
599 599  
600 -The motion controller used in serial mode is not the same as the motion controller use in RC mode. RC mode is intended to add functionality to what would be considered "normal" RC behavior based on PWM input.

602 -====== __A1. Angular Stiffness (**AS**)__ ======
577 +Ex: #5QN<cr> might return *5QN~_~_<cr>
603 603  
604 -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.
579 +The number in the response is the servo's serial number which is set and cannot be changed.

611 -A negative value on the other hand:
585 +The integer in the reply represents the firmware version with one decimal, in this example being 1.1
612 612  
613 -* Causes a slower acceleration to the travel speed, and a slower deceleration
614 -* Allows the target position to deviate more from its position before additional torque is applied to bring it back
587 +====== __26. Query Status (**Q**)__ ======
615 615  
616 -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.
589 +Ex: #5Q<cr> might return *5Q6<cr>, which indicates the motor is holding a position.

619 619  
620 -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.

631 631  
632 -The angular holding stiffness determines the servo's ability to hold a desired position under load. 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. Note that when  considering altering a stiffness value, the end effect depends on the mode being tested.
