Absolute Positioning (MODE 5)

Definition
With absolute positioning, the 1PosU moves the drive toward absolute destinations. To do
this, the axis must be synchronized.
Absolute positioning is not possible at activated dosing operation.
Supply the control interface with the destination, and start MODE 5 with the necessary
directional enable (DIR_M, DIR_P). The 1PosU moves the drive at the preset speed (control
bit SPEED) toward the destination. At the switchover point the 1PosU switches from rapid
feed to creep feed, and at the switch-off it terminates the run.
If you start during an active run, the 1PosU executes the necessary change in direction after
the time T
Linear axis
The 1PosU determines the direction the destination is to be approached from. You must set
the necessary directional enable (DIR_M, DIR_P) to start. You can also set both enables.
