17．Positioning mode (pushing operation)
(2) Setting list
The following table indicates the point table settings that may be displayed.
Specify the target position, servo motor speed, acceleration time
constant, deceleration time constant, dwell, auxiliary function, M code,
and point table for setting the pushing torque.

Set the travel distance.
When the pushing operation is selected with the auxiliary function
"16" or "18", the limit position that operates in the pushing operation is
set.
Servomotor
Rotational speed/
Speed limit value
Set the command rotation speed of the servo motor during positioning
execution.
When pushing operation is selected by auxiliary function "16" or "18",
the speed limit value during pushing operation is set.
Set the value below the permissible rotation speed of the servo motor
to be used. If a value higher than the permissible speed is set, it will
be clamped to the permissible speed.
Positioning mode During the pushing operation of the point table
method, if the setting exceeds the [Pr. PS05 pushing operation speed
upper limit value], the speed is limited by the speed of [Pr. PS05].
Acceleration time
constant
Set a time until the servo motor rotates at the rated speed.
Deceleration time
constant
Set a time from when the servo motor rotates at the rated speed
until when the motor stops.
This function is effective when the point table is selected by the input
signal.
If the auxiliary function is set to "0", "2", "16" or "18", the dwell of this
point table becomes invalid.
Set "1", "3", "8" or "9" for the auxiliary function, and change the speed
when dwell = 0.
When the dwell is set, the position command for the selected point
table is completed, and the position command for the next point table
starts after the set dwell has elapsed.
When performing the pushing operation, always set “0” to the dwell of
the point table immediately before the pushing operation. (Note 4)
This function is effective when the point table is selected by the input
signal.
(1) When using this point table in the absolute value command
method
0: Executes one selected point table automatic operation
1: Automatic continuous operation without stopping the next point
table
8: Execute automatic continuous operation to the selected point table
at startup
9: Execute automatic continuous operation to point table number 1
(2) When using this point table in the incremental value command
method
2: Execute one selected point table automatic operation
3: Automatic continuous operation without stopping the next point
table
10: Execute automatic continuous operation to the selected point
table at startup
11: Execute automatic continuous operation to point table number 1
(3) When using this point table in pushing operation (absolute value
command method)
16: Pushing operation is continued until the next point table is
executed when ST1 (start signal) is turned on. Set the pushing limit
position as an absolute value. Set following the positioning operation
using the auxiliary function "1" or "3". (Note 3) (Note 4)
(4) When using this point table in pushing operation (incremental
value command method)
18: Pushing operation is continued until the next point table is
executed when ST1 (start signal) is turned on. Set the pushing limit
position with the increment value. Set following the positioning
operation using the auxiliary function "1" or "3". (Note 3) (Note 4)
If a different rotation direction is set, the motor rotates in the reverse
direction after checking for smoothing zero (command output).
If "1" or "3" is set for point table number 255, [AL. 61] will be
