4. OPERATION
(2) Point table
(a) Point table setting
Up to 15 point tables may be set. To use point table No.s 4 to 15, however, the point table No.
selection 3 signal (DI2) and/or point table No. selection 4 signal (DI3) should be made valid in "I/O
Devices" on the Servo Configuration Software.
Set the point tables using the Servo Configuration Software or the servo amplifier operation section.
The following table lists what to set:
Name Setting Range
Absolute value
command system:
999999 to 999999
Position data
Incremental value
command system:
0 to 999999
Motor speed 0 to permissible speed
Acceleration
0 to 20000
time constant
Deceleration
0 to 20000
time constant
Dwell time 0 to 20000
Auxiliary

function
(b) Selection of point table
Using the input signal or communication function, select the point table No. with a command from
the command device (controller) such as a personal computer.
The following table lists the point table No. selected in response to the input signals/commands.
Note that when the input signals are used, the point tables used as standard are No.1 to 3. To use
No.4 to 15, the point table No. selection 3 input signal (DI2) and/or point table No. selection 4 input
signal (DI3) should be made valid in "I/O Devices" (Refer to Chapter 6) on the Servo Configuration.
When the communication function is used to select the point tables, refer to Chapter 8 for details of
the command transmission method, etc.
Unit
In the absolute value command system, motion is made to the set address.
In the incremental value command system, motion is made over the set
distance.
[ 10 m]
SM
Use the parameter to select the incremental value command or absolute
value command.
A negative value cannot be set to the incremental value 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.
Set the acceleration time constant.
ms
Set the time until the rated speed of the servo motor is reached.
Set the deceleration time constant.
ms
Set the time until the servo motor running at rated speed comes to a stop.
Set the dwell time.
Set "0" in the auxiliary function to make the dwell time invalid.
Set "1" in the auxiliary function and 0 in the dwell time to perform
ms continuous operation.
When the dwell time is set, the position command of the selected point
table is completed, and after the set dwell time has elapsed, the position
command of the next point table is started.
Set the auxiliary function.
Set "1" to execute point tables consecutively without a stop.
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.15 results in an error.
