Description

This command moves the axis in closed loop control from wherever the axis happens to

be when the command is issued to the Requested Position using the Requested

Speed, Acceleration Rate, and Deceleration Rate. The axis will stop at the

Requested Position and hold that position in closed-loop control. If the axis is moving

when this command is issued, it will start at that velocity and ramp to the requested

velocity.
The Direction parameter is required only for rotary axes. For linear axes, it has no effect,

and may be left at the default of Nearest (0).
The Move Absolute command generates a profile as shown in the plot below. The

acceleration and deceleration are rounded, producing an "s-curve" velocity profile for

smoother starts and stops.
