Acceleration and Deceleration Operations Section 7-4
For example, if the physical position is 5,368,709,120 (command units), as
indicated by point P in the above diagram, which exceeds 2,147,483,647
(command units), 1,073,741,824 will be given as the present position (com-
mand units).
The position range for the ABSOLUTE MOVEMENT and RELATIVE MOVE-
MENT commands is
−
2,147,483,648 to 2,147,483,647 (command units) for
the command present position when they are not limited by limit input signals
or software limits.
If the physical position is point P in the diagram, the physical position that can
be moved to using ABSOLUTE MOVEMENT or RELATIVE MOVEMENT is
2,147,483,648 to 6,442,450,943 (command units). The PCU will treat the
position command value and present position in the range as
−
2,147,483,648
to 2,147,483,647 (command units).
Note With the direct operation position range, the operation for position command
values is different for ABSOLUTE MOVEMENT and RELATIVE MOVEMENT
commands. Refer to
9-4-1 Starting Direct Operation for further details.
7-4 Acceleration and Deceleration Operations
The acceleration and deceleration operations that can be used when the PCU
is connected to a G-series Servo Drive, W-series Servo Drive, or SMART-
STEP Junior Servo Drive are described here.
7-4-1 Overview of Acceleration/Deceleration Operations
The PCU creates the specified acceleration/deceleration curve for the operat-
ing commands performing position control, such as direct operation or origin
searches. The acceleration/deceleration speed settings are set for each axis
according to the Servo Parameters for acceleration/deceleration and are
enabled for the following acceleration/deceleration operations.
