4.2.4 Absolute value command/incremental value command specifying system

This system is an auxiliary function for point tables to use them by specifying the absolute value
command and incremental value command.
(1) Point table
Set each value of point tables by using MR Configurator (Setup software) or operation section.
Set to point tables the following, "Position data", "Servo motor speed", "Acceleration time constant",
"Deceleration time constant", "Dwell time" and "Auxiliary function".
To specify the command system, set "Auxiliary function" as shown below.
For absolute value command system, set "0" or "1".
For incremental value command system, set "2" or "3".

Unit
(1) When this point table is used in an absolute value command system
Set the target address (absolute value).
This value can also be set using the teaching function. (Refer to section
7.10.)

m
STM
(2) When this point table is used in an incremental value command system
Set the moving distance. A " " sign indicates a reverse rotation
command.
The teaching function is unusable.
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.
Set "0" or "2" in the auxiliary function to make the dwell invalid.
Set "1" or "3" in the auxiliary function and 0 in the dwell to perform
ms
continuous operation.
When the dwell is set, the position command of the selected point table is
completed, and after the set dwell has elapsed, the position command of the
next point table is started.
Set the auxiliary function.
(1) When this point table is used in an 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 this point table is used in an 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" or "3" in point table No.31 results in an error.
For full information, refer to section 4.2.6.
