4. HOW TO USE THE POINT TABLE
(2) Incremental value command method
(a) Point table
Set the point table values using MR Configurator2 or the operation section.
Set the position data, servo motor speed, acceleration time constant, deceleration time constant,
dwell and sub function to the point table.
When you set a value outside the setting range to the point table, the set value will be clamped with
the maximum or minimum value. When changing the command unit or the connected motor results
in the set value outside the setting range, [AL. 37] will occur.
Item Setting range
Position data 0 to 999999 (Note)
Servo motor 0 to permissible
speed speed
Acceleration
0 to 20000
time constant
Deceleration
0 to 20000
time constant
Dwell 0 to 20000
Sub function 0, 1, 8 to 9
M code 0 to 99
Note. The setting range of the position data in degrees is 0 to 999.999. When the unit of the position data is μm or inch, the location of
the decimal point is changed according to the STM setting.
Unit

×10 μm
Set the travel distance.
(STM-4)
×10 inch
The teaching function is not available. When teaching is executed, the setting
-3
will not be completed.
×10 degree
The unit can be changed by [Pr. PT03] (Feed length multiplication).
pulse
Set the command speed of the servo motor for execution of positioning.
r/min
The setting value must be the permissible instantaneous speed or less of the
mm/s
servo motor used.
ms Set a time until the servo motor rotates at the rated speed.
Set a time from when the servo motor rotates at the rated speed until when
ms
the motor stops.
Set the dwell.
To disable the dwell, set "0" to the sub function.
To perform continuous operation, set "1", "8" or "9" to the sub function and 0
ms
to the dwell.
When the dwell is set, the position command of the selected point table is
completed, and after the set dwell has elapsed, the position command of the
next point table is started.
Set the sub function.
0: Automatic operation is performed in accordance with a single point table
selected.
1: Automatic continuous operation is performed to the next point table without
a stop.
8: Automatic continuous operation is performed without a stop to the point
table selected at start-up.
9: Automatic continuous operation is performed without stopping a point table
No. 1.

Outputs the first digit and the second digit of the M code in 4-bit binary
respectively.
