Independent Axis Positioning
In this mode, motion between the specified axes is independent, and each axis follows its own profile. The user
specifies the desired absolute position (PA) or relative position (PR), slew speed (SP), acceleration ramp (AC), and
deceleration ramp (DC), for each axis. On begin (BG), the DMC-40x0 profiler generates the corresponding
trapezoidal or triangular velocity profile and position trajectory. The controller determines a new command
position along the trajectory every sample period until the specified profile is complete. Motion is complete when
the last position command is sent by the DMC-40x0 profiler. Note: The actual motor motion may not be complete
when the profile has been completed, however, the next motion command may be specified.
The Begin (BG) command can be issued for all axes either simultaneously or independently. XYZ or W axis
specifiers are required to select the axes for motion. When no axes are specified, this causes motion to begin on all
axes.
The speed (SP) and the acceleration (AC) can be changed at any time during motion, however, the deceleration
(DC) and position (PR or PA) cannot be changed until motion is complete. Remember, motion is complete when the
profiler is finished, not when the actual motor is in position. The Stop command (ST) can be issued at any time to
decelerate the motor to a stop before it reaches its final position.
An incremental position movement (IP) may be specified during motion as long as the additional move is in the
same direction. Here, the user specifies the desired position increment, n. The new target is equal to the old
target plus the increment, n. Upon receiving the IP command, a revised profile will be generated for motion
towards the new end position. The IP command does not require a begin. Note: If the motor is not moving, the IP
command is equivalent to the PR and BG command combination.
