Absolute Value Command System - Mitsubishi Electric MR-J2S-CP Instruction Manual

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
Position data 999999 to 999999
Motor speed 0 to permissible speed
Acceleration
0 to 20000
time constant
Deceleration
0 to 20000
time constant
Dwell 0 to 20000
Auxiliary
0 1
function
(2) Parameter setting
Set the following parameters to perform automatic operation.
(a) Command mode selection (parameter No.0)
Select the absolute value command system.
Unit
Set the target address (absolute value).
This value can also be set using the teaching function. (Refer to section
[ 10 m] 7.10.)
STM
The unit can be changed using feed length multiplication factor selection of
parameter No. 1.
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" in the auxiliary function to make the dwell invalid.
Set "1" in the auxiliary function and 0 in the dwell to perform continuous
ms 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.
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.
