<Initialization of position information according to command position setup>
Upon receiving a command from the host controller, servo driver initializes the internal command position to the setting
value while maintaining the current position deviation, and then determines the motor actual position by subtracting
position deviation from the setting value. As a result, the motor position is initialized to the presumed position even if
the motor moves after the host controller has issued a command provided that the internal command position (after
filter) is stopped.
 Expected application: Homing with respect to latched position
(High accuracy required: internal command position is initialized to the setting value after
positioning to the latched position)
