(2) When the Coordinates are the Rotary Type
When using a rotary type coordinates such as with a rotary table, set PnB20 to 1 (shortest path), to 2 (forward),
or to 3 (reverse). Then set the end point of rotational coordinates in PnB21 and the starting point of rotational
coordinates in PnB23.
The software limit function will be disabled.
If PnB20 is set to 1 (shortest path), the motor will rotate in the shortest direction (forward or reverse) when the
target position is specified as an absolute position.
If PnB20 is set to 2 (forward), the motor will always rotate in the forward direction when the target position is
specified as an absolute position.
If PnB20 is set to 3 (reverse), the motor will always rotate in the reverse direction when the target position is
specified as an absolute position.
If the target position is specified as an relative position, the motor will rotate in the specified direction regard-
less of the setting of PnB20.
<Example>
• PnB21 = +3599, PnB23 = 0
PnB21 = +3599

Even when equipment like a rotary table is used, if multiple turns cannot be performed set the coordinate as
linear type (PnB20 = 0).
In this case, the values set in PnB21 and PnB23 are the values of the software limits.
When using rotary type coordinates and an absolute encoder, set the multi-turn limit
(Pn205).
For details on setting the multi-turn limit, refer to the User's Manual, Design and Mainte-
nance for your SERVOPACK.
