7.11 Cautions for Positioning Operation
2) If the travel distance of the second speed is small
If the travel time at the second speed is smaller than the time
*1
needed to decelerate from the operation
speed 2, deceleration is started from operation speed 1.
If the travel distance at the second speed is zero, the operation decelerates to stop for the travel distance
to be the target address 1 as if it were a 1-speed positioning operation. (No error is caused.)
*1.
For the relation between the time for the actual deceleration and the specified time for desired
deceleration, refer to the following.
→
Refer to Section 7.2
*2.
Set approximate S-shaped acceleration/deceleration or trapezoidal acceleration/deceleration in
"acceleration/deceleration mode."
