4. HOW TO USE THE POINT TABLE
4 - 15
(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 auxiliary 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 Unit Description
Position data 0 to 999999 (Note 1)
×10
STM
μ
m
×10
(STM-4)
inch
×10
-3
degree
pulse
Set the travel distance.
The teaching function is not available. When teaching is executed, the setting
will not be completed.
The unit can be changed by [Pr. PT03] (Feed length multiplication).
Servo motor
speed 0 to permissible
speed
r/min
mm/s (Note 2)
Set the command speed of the servo motor for execution of positioning.
The setting value must be the permissible instantaneous speed or less of the
servo motor used.
Acceleration
time constant
0 to 20000 ms Set a time until the servo motor rotates at the rated speed.
Deceleration
time constant
0 to 20000 ms
Set a time from when the servo motor rotates at the rated speed until when
the motor stops.
Dwell 0 to 20000 ms
Set the dwell.
To disable the dwell, set "0" to the auxiliary function.
To perform varying-speed operation, set "1", "8" or "9" to the auxiliary function
and 0 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.
Auxiliary
function
0, 1, 8 to 9
Set the auxiliary 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.
Refer to section 4.2.2 for details.
M code 0 to 99
Outputs the first digit and the second digit of the M code in 4-bit binary
respectively.
Note 1. The setting range of the position data in degrees is 0 to 999.999. When the unit of the position data is
μ
m or inch, the location
of the decimal point is changed according to the STM setting.
2. The unit will be "mm/s" for the linear servo motor control mode.
