completion
1) Set the Operation speed 1 and Target address 1 (travel distance after interrupt input).
2) Select the interrupt 1-speed constant quantity feed from the operation patterns and activate the START
command to start the interrupt 1-speed constant quantity feed (above figure).
(The positioning completion signal is turned OFF.)
3) At interrupt input (INT0) ON, the work piece moves at the operation speed 1 to the target address 1,
where the operation ends and the positioning copletion signal turns ON.
Note
The travel distance for target address 1 must be larger than the deceleration distance to stop.
If the travel distance for target address 1 is smaller, the work piece decelerates as much as possible, and the
operation stops.
2. Operation speed
Actual operation speed is "operation speed 1 x override setting."
Operation speed 1 can be changed using the operation speed change function except for the following
conditions.
• During deceleration operation
• When the speed change disable during operation signal is ON.
3. Address specification
Specified addresses are handled as relative addresses (travel distance from the current address).
(Relative/Absolute address specification is ignored.)
4. Rotation Direction
The sign of the target address decides the operation direction.
+: Operates in the direction that increases the current value. (When the value is 0, it is regarded as 1.)
-: Operates in the direction that decreases the current value.
