Positioning

Positioning is done in operation mode "Reference positioning" via the definition of the
positioning distance or in operation mode "Axle positioning" via the definition of the
position angle.
Reference positioning uses a digital reference signal from a selectable signal source
for positioning the drive independent of the speed.
Axle positioning uses a digital reference signal from a speed sensor.
The function "Reference positioning" is available in configurations 110, 210, 410, 510
and 610 and is activated by selecting operation mode 1 for parameter
458.

12.6.1 Reference Positioning
The feedback of the current position is referred to the revolutions of the motors rela-
tive to the time of the reference signal. The accuracy of the positioning for the appli-
cation to be realized is dependent on the current
ation (clockwise)
460 and the parameterized control behavior.
tance
The distance between the reference point and the required position is to be defined
in motor revolutions. The calculation of the distance covered is done with the select-
