3.3.1.6 Active motor data parameters
The following parameters contain the active motor data. Using parameter Px.14.0.0, it is possible to
determine which motor data shall be assumed as active motor data after reinitialisation
è Fig.35.
ID Px. Parameters Description
Specifies whether the user specific motor data should be adop-
ted as the active motor data following reinitialisation.
–
0: motor data from the EEPROM of the encoder
– 1: user-specific motor data from device memory
Access read/write

Specifies the number of pole pairs of the active motor -> data
sheet of the motor.

Specifies the inertia of the active motor -> data sheet of the
motor used.

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.
