Automatic Operation Mode - Mitsubishi Electric MELSERVO-J4 Instruction Manual

4. HOW TO USE THE POINT TABLE

4.2 Automatic operation mode

4.2.1 Automatic operation mode
(1) Command method
Set point tables in advance, and select any point table by using an input signal or RS422
communication. Start operation using ST1 (Forward rotation start) or ST2 (Reverse rotation start).
Absolute value command method and incremental value command method are provided in automatic
operation mode.
(a) Absolute value command method
As position data, set the target address to be reached.
1) Millimeter, inch, and pulse unit
Setting range: -999999 to 999999 [×10
2) Degree unit
Set the target position by indicating the CCW direction with a "+" sign and the CW direction with a
"-" sign.
Under the absolute value command method, the rotation direction can be specified with a "+" or
"-" sign.
An example of setting is shown below.

Coordinate system in degrees
Based on the position of 0 degree,
in the "+" direction, the servo motor rotates from the
position of 0 to 90 to 180 to 270 to 0 [degree].
In the "-" direction, the servo motor rotates from the
position of 0 to -90 to -180 to -270 to -360 [degree].
The positions of 270 degrees and -90 degrees are the
same.
The positions of 0 degree, 360 degrees and -360
degrees are the same.
