• In continuous path control, the positioning may be completed before the set address/movement amount by
the distance l, and the data may switch to the "positioning data that will run next". The value of the distance
l is as follows:
0 l < (Moving distance in 0.9ms at the command speed)
Acceleration/deceleration (setting)
V
Positioning data
No.1
V1
V2
Less than 0.9ms
The distance l is output when the next positioning data is running at the specified speed. Therefore, the
execution time of the next positioning data may be longer than the set execution time.
problem, take one of the following measures.
Use the function "output timing selection of near pass control".
• By selecting "At deceleration" as an output timing, the positioning execution time of the next positioning
data remains the same as it was set. ( Page 527, Section 12.3.4)
Use the "speed change function".
• Change speed using the speed change function instead of continuous path control. ( Page 543,
Section 12.5.1)

When the command speed V1 of a positioning data and the command speed V2 of the next positioning data is different
significantly, and V1 > V2
For positioning data in which automatic deceleration is set, the positioning is completed at the set address.
Therefore, in continuous path control, the address where a positioning is completed may be different from the
set address. However, the address will be the specified one on completion of automatic deceleration for
continuous positioning control (01) or positioning complete (00).
In the continuous path control, a speed variation will not occur using the near-pass function when the positioning data No. is
switched. ( Page 525, Section 12.3.3)
