13. POSITIONING MODE
13.3.2 Automatic operation using point table
(1) One-time positioning operation
(a) Absolute value command system
1) Point table
Set the point table values by using MR Configurator or the operation section.
Set the position data, servo motor speed, acceleration time constant, deceleration time constant,
dwell and auxiliary function in the point table.
Setting "0" or "1" in the auxiliary function sets the point table to the absolute value command system.
Setting "2" or "3" in the auxiliary function sets the point table to the incremental value command
system.
Item Setting range
Position data -999999 to 999999
Servo motor 0 to permissible
speed speed
Acceleration time
0 to 20000
constant
Deceleration time
0 to 20000
constant
Dwell 0 to 20000
Auxiliary function 0 to 3
Unit
(1) When using this point table as absolute value command system,
set the target address (absolute value).
×10 STM μm
(2) When using this point table as incremental value command system,
set the travel distance. A "-" sign indicates a reverse rotation command.
Set the command speed of the servo motor for execution of positioning.
r/min
The setting should be equal to or less than the instantaneous permissible
speed of the servo motor.
ms
Set the time until the servo motor reaches to the rated speed.
ms
Set the time until the servo motor stops from the rated speed.
When dwell is set and the set dwell has passed after the position command of
the selected point table is completed, the position command of the next point
table is started.
ms
Set "0" in the auxiliary function to make the dwell invalid.
Set "1" in the auxiliary function and 0 in the dwell to perform varied speed
operation.
(1) When using this point table in the absolute value command system
0: Automatic operation is performed in accordance with a single point table
chosen.
1: Operation is performed in accordance with consecutive point tables
without a stop.
(2) When using this point table in the incremental value command system
2: Automatic operation is performed in accordance with a single point table
chosen.
3: Operation is performed in accordance with consecutive point tables
without a stop.
When a different rotation direction is set, smoothing zero (command output) is
confirmed and the rotation direction is then reversed.
Setting "1" in point table No. 7 results in an error.
