Program Example
3. Rotation direction
The operation direction is determined by the sign (positive/negative) of the target address I.
When the target address I sign is positive: Forward
When the target address I sign is negative: Reverse
4. Positioning completion flag
The positioning completion flag turns off when the operation starts.
The positioning completion flag turns on when the operation reaches to the target address I.
5. Interrupt input 0
The contents of the interrupt input 0 and the detection edge change as follows by the interrupt input setting
and the DOG input polarity setting.
Point
• When interrupt input 0 is on at the start of the positioning operation and the rising edge is the detection
edge, interrupt input 0 becomes valid when the signal turns OFF and then ON again.
• When interrupt input 0 is off at the start of the positioning operation and the falling edge is the detection
edge, interrupt input 0 becomes valid when the signal turns ON and then OFF again.
