Caution of the interrupt 1-speed positioning operation
• Operation when the travel amount to the target position is small
When the time required for the travel amount (target address I) is shorter than the time required for
deceleration, the operation immediately stops when the operation reaches target address I. In addition,
when the travel amount is smaller than (operation speed/1,000) × 3 pulse, variation occurs in the detection
of the interrupt input.
- During operation at 1 kHz or higher: Within 3 ms
- During operation at less than 1 kHz: Within 3 pulses
Speed
• Operation when the interrupt input 0 is detected during the acceleration
When the interrupt input 0 is detected during the acceleration, the following operation is executed
according to the size of target address I.
1) When the target address I < the number of pulses required for deceleration from the current speed
As soon as the interrupt input 0 turns on, the deceleration immediately starts. When the operation
reaches to the target address I, it immediately stops.
2) When the number of pulses required for deceleration from the current speed ≤ target address I < pulse
number required for acceleration/deceleration from the current speed
The acceleration is executed up to the position where the remaining pulse number = pulse number
required for deceleration, and then the operation decelerates and stops.
3) When the pulse number required for acceleration/deceleration from the current speed ≤ the target
address I
The operation accelerates to the operation speed I and then decelerates and stops.
Interrupt input 0
• Operation when the interrupt input 0 is not detected
The operation continues until the interrupt input 0 is detected.
