4. OPERATION


4.2.2 Absolute value command system

(1) Point table

Set the point table values using the MR Configurator (servo configuration software) or from the
operating section.
Set the position data, motor speed, acceleration time constant, deceleration time constant, dwell and
auxiliary function to the point table. The following table gives a setting example.

Name Setting

range Unit

Description

Position data

999999 to 999999

[ 10

STM

m]

Set the target address (absolute value).
This value can also be set using the teaching function. (Refer to section
7.10.)
The unit can be changed using feed length multiplication factor selection of
parameter No. 1.

Motor speed

0 to permissible speed

r/min

Set the command speed of the servo motor for execution of positioning.
The setting should be equal to or less than the instantaneous permissible
speed of the servo motor.

Acceleration
time constant

0 to 20000

ms

Set the acceleration time constant.
Set the time until the rated speed of the servo motor is reached.

Deceleration
time constant

0 to 20000

ms

Set the deceleration time constant.
Set the time until the servo motor running at rated speed comes to a stop.

Dwell

0 to 20000

ms

Set the dwell.
Set "0" in the auxiliary function to make the dwell invalid.
Set "1" in the auxiliary function and 0 in the dwell to perform 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.

Auxiliary
function

0 1

Set the auxiliary function.
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.31 results in an error.

For full information, refer to section 4.2.6.


(2) Parameter setting
