4. HOW TO USE THE POINT TABLE
4 - 15
(c) Operation
Selecting DI0 to DI4 for the point table and switching on ST1 starts positioning to the position data at
the set speed, acceleration time constant and deceleration time constant. At this time, ST2 (Reverse
rotation start) is disabled.
Item Device to be used Setting
Automatic operation mode selection MD0 (Operation mode selection 1) Switch on MD0.
Point table selection
DI0 (Point table No. selection 1)
DI1 (Point table No. selection 2)
DI2 (Point table No. selection 3)
DI3 (Point table No. selection 4)
DI4 (Point table No. selection 5)
Refer to section 4.2.1 (2) (b).
Start ST1 (Forward rotation start) Switch on ST1 to start.
(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, auxiliary function, and M code 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. If the value becomes out of the range because of the changes in
the command unit or the connected servo motor, [AL. 37] will occur.
Item Setting range Unit Description
Position data 0 to 999999 (Note)
×10
STM
μm
×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
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 for the servo motor to reach the rated speed.
Deceleration
time constant
0 to 20000 ms Set a time for the servo motor to stop from the rated speed.
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, a positioning of the next point table will be started after
the positioning of the selected data is completed, and the set dwell has
elapsed.
Auxiliary
function
0, 1, 8, 9
Set the auxiliary function.
0: Executes automatic operation for a selected point table.
1: Executes automatic continuous operation without stopping for the next point
table.
8: Executes automatic continuous operation without stopping for the point
table selected at the start.
9: Executes automatic continuous operation without stopping for the point
table No. 1.
Setting "1" to point table No. 31 results in an error.
For details, refer to (3) (b) in this section.
M code 0 to 99
Outputs the first digit and the second digit of the M code in 4-bit binary
respectively.
M code will be available in the future.
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.
