(4) Timing chart
The following timing chart shows that an operation is performed at a stop of the station No. 0 when
servo-on.
Number of stations: 8

POINT
Always perform a home position return. Executing positioning operation without
home position return will trigger [AL. 90 Home position return incomplete
warning] and ST1 (Forward rotation start) will be disabled.
When travel distances are the same to a target station position from CCW and
from CW, the shaft will rotate to the station No. increasing direction.
