Almost everything one might expect to be able to configure for a smart servo motor is available. 9 9 10 -In order to have servos react differently when commands are sent to all servos in a serial bus, the first step a user should take is to assign a different ID number to each servo (explained below).

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).114 +{In progress} 109 109 116 +A "virtual position" is one which allows for multiple rotations of the output horn, moving the center position and more.

Query Voltage (**QV**)__ ====== 619 619 620 - Thisreduces the angularstiffness to -2 for that session, allowing the servo to deviatemore around the desired position. This can be beneficial in many situations such as impacts (legged robots) where more of a "spring" effectis desired. Upon reset, the servo willuse the value stored inmemory, based on the lastconfiguration command.603 +Ex: #5QV<cr> might return *5QV11200<cr> 621 621 622 - Ex:#5QAS<cr>605 +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). 623 623 624 -Quer iesthevaluebeingused.607 +====== __28.

To convert from degrees Celcius to degrees Farenheit, multiply by 1.8 and add 32. Therefore 56.4C = 133.52F. 629 629 630 -====== __ A2.AngularHolding Stiffness(**AH**)__ ======613 +====== __29. Query Current (**QC**)__ ====== 631 631 632 - Theangularholding stiffness determines the servo's abilityto hold a desired positionunderload. The default value for stiffnessdepending on the firmware may be 0 or1. Greater values produce increasingly erratic behavior and the effect becomes extreme below -4and above +4. Maximum values are -10to +10. Note that whenconsidering altering a stiffness value, the end effect depends on the mode being tested.615 +Ex: #5QC<cr> might return *5QC140<cr> 633 633 634 - Ex:#5AH3<cr>617 +The units are in milliamps, so in the example above, the servo is consuming 140mA, or 0.14A. 635 635 636 - Thissetstheholding stiffnessforservo #5 to 3 for that session.619 +====== __30. RC Mode (**CRC**)__ ====== 637 637 638 - QueryAngularHoldStiffness(**QAH**)621 +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. 639 639 640 -Ex: #5QAH<cr> might return *5QAH3<cr> 623 +|**Command sent**|**Note** 624 +|ex: #5CRC<cr>|Stay in smart mode. 625 +|ex: #5CRC1<cr>|Change to RC position mode. 626 +|ex: #5CRC2<cr>|Change to RC continuous (wheel) mode. 627 +|ex: #5CRC*<cr>|Where * is any number or value.

Note thatwhen consideringalteringa stiffness value,the end effectdepends onthemodebeingtested.635 +This command does a "soft reset" (no power cycle required) and reverts all commands to those stored in EEPROM (i.e. configuration commands). 649 649 650 -====== __ A3:AngularAcceleration (**AA**)__ ======637 +====== __32. DEFAULT & CONFIRM__ ====== 651 651 652 - The default value for angular acceleration is 100, which is the same as the maximumdeceleration.Accepts values of between 1 and 100. Increments of 10 degrees per second squared.639 +Ex: #5DEFAULT<cr> 653 653 654 - Ex:#5AA30<cr>641 +This command sets in motion the reset 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. 655 655 656 - QueryAngularAcceleration(**QAD**)643 +EX: #5DEFAULT<cr> followed by #5CONFIRM<cr> 657 657 658 - Ex:#5QA<cr>might return*5QA30<cr>645 +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 leave the firmware action. 659 659 660 - ConfigureAngularAcceleration(**CAD**)647 +Note that after the CONFIRM command is sent, the servo will automatically perform a RESET. 661 661 662 -E x:#5CA30<cr>649 +====== __33.

This is useful should the button be broken or inaccessible. The servo then waits for the CONFIRM command.

As such, the servo will move at full speed for all motion commands. The command EM1 enables use of the motion controller. 681 - 682 -Note that if the modifiers S or T are used, it is assumed that motion control is desired, and for that command, EM1 will be used. 683 - 684 -====== __A6. Configure LED Blinking (**CLB**)__ ====== 685 - 686 -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. The command requires that the servo be RESET. Here is the list and their associated value: 687 - 688 -(% style="width:195px" %) 689 -|(% style="width:134px" %)**Blink While:**|(% style="width:58px" %)**#** 690 -|(% style="width:134px" %)No blinking|(% style="width:58px" %)0 691 -|(% style="width:134px" %)Limp|(% style="width:58px" %)1 692 -|(% style="width:134px" %)Holding|(% style="width:58px" %)2 693 -|(% style="width:134px" %)Accelerating|(% style="width:58px" %)4 694 -|(% style="width:134px" %)Decelerating|(% style="width:58px" %)8 695 -|(% style="width:134px" %)Free|(% style="width:58px" %)16 696 -|(% style="width:134px" %)Travelling|(% style="width:58px" %)32 697 -|(% style="width:134px" %)Always blink|(% style="width:58px" %)63 698 - 699 -To set blinking, use CLB with the value of your choosing. To activate blinking in multiple status, simply add together the values of the corresponding status. See examples below: 700 - 701 -Ex: #5CLB0<cr> to turn off all blinking (LED always solid) 702 -Ex: #5CLB1<cr> only blink when limp (1) 703 -Ex: #5CLB2<cr> only blink when holding (2) 704 -Ex: #5CLB12<cr> only blink when accel or decel (accel 4 + decel 8 = 12) 705 -Ex: #5CLB48<cr> only blink when free or travel (free 16 + travel 32 = 48) 706 -Ex: #5CLB63<cr> blink in all status (1 + 2 + 4 + 8 + 16 + 32) 707 - 708 -RESETTING the servo is needed. 659 +Note that after the CONFIRM command is sent, the servo will automatically perform a RESET.
