BONFIGLIOLI ACTIVE Cube ACU 401-23 User Manual

12.6 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 sele
ctable 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

mode
458.
The function "Axle positioning" is available in configurations 210 and 510 (Parameter
Configuration 30) and is activated by selecting operation mode 2 for parameter Op-
eration mode
458.

1 - Reference positioning
Positioning from reference point via definition of
positioning distance (rotations). The reference
point is acquired via a
Signal Source 459.
Available in Configuration: 110, 210, 410, 510,
610.
2 - Axle positioning
Reference positioning via definition of the posi-
tioning angle, reference signal from speed sen-
sor.
Available in Configuration: 210, 510.
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
Actual frequency 241, the deceler-
ation (clockwise)
421, the No. of pole pairs 373, the selected Positioning dis-
tance
460 and the parameterized control behavior.
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-
ed
Positioning distance 460 according to the application.
The setting 0.000 U for the Positioning distance 460
causes an immediate stop of
the drive according to the selected stopping behavior for
Operation mode

The actual value parameter Revolutions 470 facilitates the setting and optimization
of the function. The revolutions of the motor displayed should correspond to the Po-
sitioning distance 460 at the required position.
