BONFIGLIOLI ACTIVE Cube ACU 201-11 User Manual

The positioning is started by a start command from a signal source (e.g. digital input)
which must be assigned to the parameter Start Positioning of Axle 37
. The signal
source can be selected from the operation modes for digital inputs described in chap-
ter "
Digital inputs".
The positioning starts on condition that the Actual frequency 241 of the output sig-
nal is smaller than the value entered in parameter
Positioning frequency 471
. Due to
a stopping behavior, the actual frequency drops below the positioning frequency.

Via parameter Time constant positioning controller 479, the time constant for con-
trolling the positional error can be set. The value of the time constant should be in-
creased if oscillations of the drive around the
reference orientation occur during the
positioning.

To make sure that the set position is maintained if a load torque is applied, a stop-
ping behavior should be selected for parameter Operation mode 630 which impress-
es a starting current either permanently when the drive is at a standstill or for the
stopping time.
The status message “60 - Target Position Reached” which is displayed when the ref-
erence orientation is reached can be assigned to a digital output. The message is
output on the following conditions:
− Operation mode 2 (axle positioning) for parameter Operation mode 458 is se-
lected.
− The controller enable si
gnal at digital inputs S1IND/STOA and S7IND/STOB is
switched on.
− Start Positioning of Axle 37 is activated.
−
The speed sensor monitoring is activated, i.e. operation mode 2 (error message)
for parameter Operation mode 760 of the speed sensor monitoring is selected.
−
Operation mode 1004 or 1104 (quadruple evaluation with reference impulse) is
selected for the speed sensor input.
− The actual frequency 241 is smaller than 1 Hz.
−
The deviation of the current position from the reference orientation is smaller
than the max. orientation error 472.
