P
The outline of the "overview of positioning control", "overview of independent
positioning control and continuous positioning control", "overview of block positioning
control" and "overview of acceleration/deceleration processing control" is shown below.
ositioning control
An overview of positioning using positioning data is 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 addresses are 2000 and 8000:
2000
[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
• For negative travel increment......Positioning in the negative direction
[Example]
The following figure shows the operations when the start point address
is 5000 and the travel increments are 3000 and -3000:
2000
Movement direction for a negative
movement amount.
5000
5000
Movement direction for a positive
movement amount.
