Table Operation
Note
• Interrupt input is detected in the order of INT0 and INT1.
• 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.
→ For details, refer to Subsection 7.11.2
2. Operation speed
The actual operation speed is decided by the following calculation formulas.
- Operation speed 1 × Override setting
- Operation speed 2 × Override setting
The actual operation speed 1 and operation speed 2 can be changed using the operation speed change
function except under the following conditions.
→ For change of the operation speed, refer to Section 7.6
• During deceleration operation from operation speed 2
• 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).
(The absolute/relative 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.
