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.

Command Summary - Independent Axis

COMMAND

PR x,y,z,w

PA x,y,z,w

SP x,y,z,w

AC x,y,z,w

DC x,y,z,w

BG XYZW

ST XYZW

IP x,y,z,w

IT x,y,z,w

AM XYZW

MC XYZW

DESCRIPTION

Specifies relative distance Specifies absolute position Specifies slew speed Specifies acceleration rate Specifies deceleration rate Starts motion

Stops motion before end of move Changes position target

Time constant for independent motion smoothing Trippoint for profiler complete

Trippoint for "in position"

The lower case specifiers (x,y,z,w) represent position values for each axis. The DMC-13X8 also allows use of single axis specifiers such as PRY=2000.

DESCRIPTION

Return acceleration rate for the axis specified by ‘x’ Return deceleration rate for the axis specified by ‘x’ Returns the speed for the axis specified by ‘x’

Returns current destination if ‘x’ axis is moving, otherwise returns the current commanded position if in a move.

Returns current incremental distance specified for the ‘x’ axis

Example - Absolute Position Movement

PA 10000,20000	Specify absolute X,Y position
AC 1000000,1000000	Acceleration for X,Y
DC 1000000,1000000	Deceleration for X,Y
SP 50000,30000	Speeds for X,Y
BG XY	Begin motion

Example - Multiple Move Sequence
