<title>Commands</title>
<para>The Astrium velocity selector is a SICS script context object. There are 2 parts, the
script context object, which has the name
<command>/instrument/velocity_selector</command> and the 2 driveable interfaces to the
object, which have the names <command>nvs_speed</command> and
<command>nvs_lambda</command>. Hence you can <command>drive</command> and
<command>run</command>
<command>nvs_speed</command> and <command>nvs_lambda</command>. To get and set other
parameters use <command>hget</command> or <command>hset
/instrument/velocity_selector/</command></para>
