External Command Positioning Operation

By the external command positioning operation start command, the operation starts with operation speed I,
detects the rise/fall edge of interrupt input 0, and changes the speed to operation speed II. Then, the rise/fall
edge of the interrupt input 1 is detected and stops immediately.
1. Operation
1) Set operation speed I and operation speed II.
2) When the operation command to start external command positioning operation is turned from off to on,
the external command positioning operation starts with operation speed I. (The positioning completion
flag turns off.)
3) When interrupt input 0 is detected, the speed changes to operation speed II.
4) When interrupt input 1 is detected, the operation immediately stops, and the operation completes by
turning on the positioning completion flag.

Point
When the interrupt input 1 is detected before the interrupt input 0 is detected, the operation immediately
stops.
2. Rotation direction
The rotating direction is determined by the sign (positive/negative) of the operation speed I.
• Operation speed Ι > 0: Forward
• Operation speed Ι < 0: Reverse
Point
When the signs (positive/negative) of the operation speed I and the operation speed II are different, the 2-
speed is operated with the bias speed. However, if the bias speed is 0, the operation is executed at 1 Hz.
