3.3.3.10 Parameters of the direction of rotation manager
The following parameters influence the direction of rotation of the drive:
ID Px. Parameters Description
Determines whether the reversal of the direction of rotation
shall be activated.
This means:
–
0: inactive
– 1: active
Access read/write
Update reinitialization
1170 Reversing the direc-
tion of rotation
Unit −
Determines whether the encoder signal shall be inverted.
This means:
–
0: inactive (do not invert the encoder signal)
– 1: active (invert the encoder signal)
One encoder is allocated to every index
è
Index for the Invert encoder signal parameter (Px.1171).

Update reinitialization
1171 Invert encoder signal
Unit −
Specifies whether the sequence of phases is swapped. The usu-
al phase sequence for the servomotor to turn clockwise is
ascending (U, V, W). If the servomotor has the phase sequence
U, W, V, the phase sequence is reversed. 0 for the phase
sequence U, V, W and 1 for the phase sequence U, W, V. For a
stepper motor, the phase sequence for 0 is the assignment A-#A
and B-#B. For the phase sequence equal to 1, the assignment A-
#A and #B-B is. Changing the phase sequence changes the
rotating field of the motor.
