6.6.6 Absolute Positioning (MODE 5)
Definition
With absolute positioning, the 1PosSSI/Analog moves the drive toward absolute
destinations. To do this, the axis must be synchronized.
Supply the control interface with the destination, and start MODE 5 with the necessary
directional enable (DIR_M, DIR_P). The 1PosSSI/Analog moves the drive towards the
destination with the set voltage for rapid feed. At the switchover point, the 1PosSSI/Analog
decelerates from rapid to creep feed. At the switch-off point, the 1PosSSI/Analog completes
the run either directly or via the ramp depending on the parameter assignment.
If you start during a current run, the 1PosSSI/Analog executes any required change in
direction using deceleration or acceleration.
Linear axis
The 1PosSSI/Analog determines the direction from which the destination is to be
approached. You must set the necessary directional enable (DIR_M, DIR_P) to start. You
can also set both enables.
