Traversing break
Via X6/1,2, the controller of the traversing drive receives a normalised reference setpoint from the
controller of the winding drive. For determining the angle of rotation which the winding drive is to
traverse during the traversing break, calculate the speed signal of the winding drive via the FB
CONV5. CONV5 is parameterised under C0655 and C0656.
l The following formula is used to calculate the C0655/C0656 ratio:
C0655
C0656
+
max. Wickeldrehzahl [rpm]
max. Führungssollwert [%]
@ 100 %
15000 rpm
Example
l Max. winding speed = 1000 rpm
l Max. reference setpoint = 100 % (at max. winding speed)
The C0655/C0656 ratio must be 0.0666 (e.g. C0655 = 1000; C0656 = 15000).
Selecting the angle of rotation for the winding drive during the traversing break
An angle of rotation of 360 ° (one revolution) corresponds to 65536 inc. The following formula is used
to calculate the value for C0474/1:
C0474
ń1 + 65536 @ Drehwinkel
360 °
For a traversing break of half a revolution of the winding drive, 32768 must be entered under C0474/1.
Tip!
When C0474/1 = 0 is selected, the traversing drive decelerates and starts with constant
acceleration.
