1.1.4 Overview of positioning control functions
The outline of the "overview of positioning control" and "overview of individual
positioning control and continuous positioning control", "overview of block positioning
control" and "overview of acceleration/deceleration processing control" is shown below.
P
ositioning control
An overview of positioning using positioning data described below.
(1) Linear control
(a) 1-axis linear control
This performs positioning from the start point address (location the axis is
presently stopped) defined on the specified axis to the specified position.
[Control using the absolute system]
1) This performs positioning from the start point address to the specified
position.
2) The start point address and the specified address determine the
movement direction.
[Example]
The following figure shows the operations when the start point address
is 5000 and the positioning address are 2000 and 8000:
2000
5000
8000
Positioning when the specified
address is 2000
Start point address
Positioning when the specified
address is 8000
[Control using the increment system]
1) This performs positioning from the specified increment of travel from the
start point address.
2) The sign of the travel increment determines the direction of travel.
• For positive travel increment…….Positioning in the positive direction
(direction of address increase)
• For negative travel increment…...Positioning in the negative direction
(direction of address decrease)
[Example]
The following figure shows the operations when the start point address
is 5000 and the travel increments are 3000 and -3000:
2000
5000
8000
Positioning when the specified
address is -3000.
Positioning when the specified
address is 3000.
Start point address
Movement direction for a negative
movement amount.
Movement direction for a positive
movement amount.
