Table Operation
POINT
The positioning completion signal turns ON if the travel distance is 0.
If the travel distance is 0 or the travel time is too short, however, it is impossible for the sequence program to
detect the positioning completion signal turning OFF.
*1
*1. Turning OFF of the positioning completion signal can be detected when the positioning completion
signal output waiting time is set if the version is Ver.1.20 or later.
→ For details on the Positioning completion signal output waiting time, refer to Subsection 7.9.11
2. Operation Speed
The actual operation speed is "operation speed 1 × override setting."
Operation speed 1 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
• When the speed change disable during operation signal is ON.
3. Address Specification
The absolute/relative address can be specified.
With the specified absolute address: Specifies a target address (position) using address 0 as the base.
With the specified relative address: Specifies a travel distance from the current address.
4. Rotation Direction
With the specified absolute address: The rotation direction depends on whether the target address 1 is
larger or smaller than the current address.
With the specified relative address: The rotation direction is decided by the sign (positive/negative) of
target address 1.
