7.11 Cautions for Positioning Operation
5. Interrupt 2-speed constant quantity feed
If the time required for the travel distance (up to target address 1) is shorter than the time required for
deceleration
*1
, the system stops pulse outputs when it reaches the target address 1 in deceleration.
If the travel distance is "0", the system immediately stops when the interrupt input (INT1) turns ON.
*1. For the relationship between the time required for deceleration and the deceleration time (positioning
parameter), refer to the following.
→ Refer to Section 7.2
*2. Set approximate S-shaped acceleration/deceleration or trapezoidal acceleration/deceleration in
"acceleration/deceleration mode."
6. Linear interpolation operation
If the time necessary for the travel distance (target address 1) is smaller than the acceleration/deceleration
time, the actual operation speed does not reach the command speed.
7. Linear interpolation operation (interrupt stop)
If the time necessary for the travel distance (target address 1) is smaller than the deceleration time, the output
pulses stop at the deceleration target address 1 (target address 1).
If the travel distance is zero, the operation immediately stops at the interrupt input (INT0) ON.
8. Interpolation operation (during continuous pass operation)
If the travel distance is small and the travel time from the starting point to the end point is shorter than the
interpolation time constant, the operation temporarily stops, and then shifts to the next interpolation operation.
→ For cautions on continuous pass operation, refer also to Subsection 7.11.4
