During traversing, the motion parameters can also be influenced (on-the-fly setpoint acceptance) and an on-the-fly change can be undertaken between the Setup and Positioning modes. The direct setpoint specification operating mode (MDI) can also be used in positioning or setup mode if the axis is not homed. This means that on-the-fly synchronization and rehoming can be carried out with "flying referencing" (see separate section). The direct setpoint input function is activated by p2647 = 1. A distinction is made between two modes: positioning mode (p2653 = 0) and setup mode (p2653 = 1). In "positioning" mode, the parameters (position, velocity, acceleration and deceleration) can be used to carry out absolute (p2648 = 1) or relative (p2648 = 0) positioning with the parameter p2690 (fixed setpoint position). 398 Drive converter cabinet units Operating Instructions, 10/2008, A5E00288214A
