21 Offset travel distance at

1000 -99999999

99999999
0.001 mm
Offset travel distance from the ideal phase-Z position
(Positive value = Applied in the direction of moving away
from the end) (Refer to axis-specific parameter No. 76)
* Note on absolute encoders
When a value near an integer multiple of the phase-Z
distance (including an offset travel distance of 0) is set
in this parameter, the servo will lock above phase Z
upon absolute reset. As a result, the coordinates may
shift by the pulses corresponding to the phase-Z
distance. Therefore, never set a value near an integer
multiple of the phase-Z distance.
(Provide a sufficient margin with respect to the servo
amplitude.)
