(b) Incremental value command system
1) Point table
Set the point table values by using set up software(MR Configurator2
TM
) or the operation section.
Set the position data (target position), servo motor speed, acceleration time constant, deceleration
time constant, dwell and auxiliary function in the point table.

Set the travel distance.
The unit can be changed using feed length multiplication selection of

Rotation speed
0 ~ allowable
actuator speed
r/min
Sets the command rotation speed (
Motor rotations/min
) when positioning is
executed.
Acceleration time
constant
0 to 20000
ms
Set the time until the servo motor reaches to the rated speed.
(3000 r/min)
Deceleration time
constant
0 to 20000
ms
Set the time until the servo motor stops from the rated speed.
(3000 r/min
Dwell
0 to 20000
ms
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.
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.
Auxiliary function 0, 1
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.
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.
