Positioning

The basic function "Positioning" provides the functions for executing the (travel) profiles and

supports an "override" of speed and acceleration.

• A profile describes a motion request which can be implemented by this basic function into a

rotary motion.

• A profile is described via the following profile parameters: Mode (type of positioning), position,

speed, acceleration, deceleration, S-ramp time, final speed, standard sequence profile, TP

sequence profile, TP window starting and end position and touch probe signal source(s).

Note!

For positioning, setpoint speeds greater than 30000 rpm are not possible. The speeds

defined for these basic function are internally limited to 30000 rpm.
If the basic function is activated for a speed greater than 30000 rpm (e. g. if the basic

function "Speed follower" is replaced), the internal limitation of the speed setpoint

causes a speed step.
When the basic function is activated, a start acceleration is considered.

The following applies to the encoderless motor control types :
If no position controller has been selected for the position control in case of V/f control

or sensorless vector control (

= "1: Phase controller is active"), positioning is only

executed via the speed profile resulting from the profile parameters. Because of this, the

target positions set will only "roughly" be reached.
