7. HOW TO USE THE POINT TABLE
7 - 9
(c) Operation
Selecting the point table with "Target point table" and switching on "Controlword bit 4 (New set-
point)" start positioning to the position data at the set speed and the acceleration/deceleration time
constant.
Item Object/register to be used Setting
Point table mode (pt) selection Modes of operation Set "-101".
Point table selection Target point table Set the point table No. to use.
Start Controlword Switch on "Controlword bit 4 (New set-point)".
(2) Incremental value command method
POINT
The incremental value command method ([Pr. PT01] = _ _ _ 1) cannot be used
in the absolute position detection system. When using the absolute position
detection system, select the absolute value command method ([Pr. PT01] = _ _
_ 0).
(a) Point table
Set the point table values using MR Configurator2 or "Point table 001 to 255".
Set the position data, servo motor speed, acceleration time constant, deceleration time constant,
dwell, auxiliary function, and M code in the point table.
When an out of range value is set in the point table, the value will be clamped with the maximum or
minimum value in the setting 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
pulse
Set the travel distance.
The unit can be changed by [Pr. PT03] (Feed length multiplication).
Servo motor
speed 0 to permissible
speed
0.01 r/min
Set the command speed of the servo motor for execution of positioning.
The setting value must be equal to or less than the instantaneous permissible
speed 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" in the auxiliary function.
To perform a continuous operation, set "1", "8", or "9" in the auxiliary function
and "0" in the dwell.
Setting the dwell completes the position command of the selected point table,
and then starts the position command of the next point table after the set
dwell has elapsed.
Auxiliary
function
0, 1, 8, 9
Set the auxiliary function.
0: Automatic operation for one selected point table is performed.
1: Automatic operation for the next point table is performed.
8: Automatic operation for the point table selected at the start is performed.
9: Automatic operation for the point table No. 1 is performed.
Setting "1" to point table No. 255 results in an error.
Refer to section 7.4 (1) (b) for details.
M code 0 to 99
Set a code to output at the completion of positioning.
M code can be read with M code actual value (2D6Ah).
Note. When the unit of the position data is μm or inch, the location of the decimal point is changed according to the STM setting.
