Table Operation
Note
• When using linear interpolation operation (interrupt stop), the operation pattern selection should set in both
axes as linear interpolation (interrupt stop).
If the same operation pattern is not set in both axes, the following operation is executed.
1) When linear interpolation (interrupt stop) is set to the operation pattern of the X-axis and a different
operation pattern is set to the Y-axis
The operation pattern of the Y-axis is disregarded, and linear interpolation operation (interrupt stop) is
executed.
2) When an operation pattern different than linear interpolation (interrupt stop) is set to the operation
pattern of the X-axis and linear interpolation (interrupt stop) is set to the Y-axis
X-axis: Operates by the operation pattern set in the X-axis.
Y-axis: Does not operate.
• When interpolation operations are consecutively repeated in a table operation, the 20SSC-H provides
continuous pass operation.
→ For details on the continuous pass operation, refer to Section 10.10
• Pulse rate and feed rate
In versions earlier than Ver. 1.20, make sure that the ratio between the pulse rate and the feed rate is
equivalent between the X-axis and the Y-axis.
In versions Ver. 1.20 or later, if the ratio between the pulse rate and the feed rate is not equivalent between
the X-axis and the Y-axis, set "interpolation gear ratio selection" to "X/Y-axis."
→ For selection of the interpolation gear ratio, refer to Subsection 7.11.3
2. Operation speed
The actual operation speed (vector speed) is "X-axis operation speed 1 x X-axis override setting."
The operation speed 1 for the X-axis 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 amount 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.
