10.2.8 Change sense of rotation
The parameter Change sense of rotation 1199 reverses the rotating direction of the
motor.
0 -
Off
Motor rotates forward
(clockwise)
Motor rotates reverse
(anti clockwise)
1 -
On
Motor rotates reverse
(anti clockwise)
Motor rotates forward
(clockwise)
BONFIGLIOLI VECTRON defines with view on the motor A side and correct connection
of the motor phases the sense of rotation clockwise (forward) with a positive set value.
With a changed sense of rotation, the motor reverses with the same set value. Existing
gear boxes and transmissions have to be considered.
The sense of rotation can only be changed while the output stage is inhibited.
With the parameter Change sense of rotation 1199 the sense of direction of the com-
plete system (motor control and encoder evaluation) is reversed.
When the sense of direction is different between motor and encoder, this can be
changed by two actions:
1.) Change the track A and track B at the encoder inputs at the terminals of ACU.
2.)
Change the evaluation of the sense of rotation of the connected encoder with
parameter 490 respectively 493.
