Reference Positioning - BONFIGLIOLI Act 201 Operating Instructions Manual

11.6.1 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 applica-
tion to be realized is dependent on the current
tion (Clockwise)
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 selected
Positioning
The setting 0.000 U for the
drive according to the selected stopping behavior for

460 Positioning Distance
The actual value parameter

tioning distance
The minimum number of revolutions needed until the required position is reached de-
pends on the
tion Anticlockwise
Example: f = 20 Hz, a = 5 Hz/s, p = 2 ⇒ U
At an actual frequency of 20 Hz and a deceleration of 5 Hz/s, at least 20 revolutions
are required until the drive stops at the required position. This is the minimum value
for the
number of revolutions to the required position is to be lower, either the frequency
must be reduced, the deceleration must be increased or the reference point must be
shifted.
The digital signal for acquisition of the reference point and the logic link can be se-
lected by the parameter
S3IND and S6IND to further functions is to be checked according to selected
ration
function "Start of clockwise operation").
The signals for positioning and a stopping behavior should not be assigned to the same
digital input.
