18 18  Action commands tell the servo, within that session, to do something (i.e. "take an action"). 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:

52 -1. Start with a number sign # (U+0023)

Once the servo is powered off and then powered on, zeroing the servo will cause it to move to -5.0 degrees with respect to the factory origin and report its position as 0 degrees. Configuration commands can be undone / reset either by sending the servo's default value for that configuration, or by doing a factory reset (clears all configurations) described below.

653 +
654 +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).
655 +You can turn on or off blinking for various LSS status. Here is the list and their associated value: 0=No blinking, ; 63=Always blink; Blink while: 1=Limp; 2=Holding 4=Accel; 8=Decel; 16=Free 32=Travel;
656 +
657 +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:
658 +
659 +Ex: #5CLB0<cr> to turn off all blinking (LED always solid)
660 +Ex: #5CLB1<cr> only blink when limp
661 +Ex: #5CLB2<cr> only blink when holding
662 +Ex: #5CLB12<cr> only blink when accel or decel
663 +Ex: #5CLB48<cr> only blink when free or travel
664 +Ex: #5CLB63<cr> blink in all status
