1.1 Positioning control
1.1.1 Features of D75P2
The features of the D75P2 are shown below.
(1) Compatibility with distributed system
The D75P2 can be installed near distributed servo amplifiers and stepping
motors.
(2) Ease of compatibility with absolute position detection system
(a) Connection of an absolute position-compatible servo system provides
compatibility with an absolute position detection system.
(b) Once the zero point position has been established, the axis can return to
the address prior to power-on by absolute position restoration.
(c) In the absolute position detection system, the zero point position can be
established by data setting method zero point return.
This makes the wiring of near-point dogs, etc. unnecessary.
(3) Control by mechanical inputs
External inputs, such as external start, stop, and speed/position changeover,
allow positioning control to be performed without use of sequence programs.
(4) Ample positioning control functions
(a) Various functions required for the positioning system, such as positioning
control to random position, fixed-dimension feed control and uniform speed
control are provided.
1) Up to 600 positioning data items containing the positioning address,
control method and operation pattern, etc., can be set for each axis.
Positioning for each axis is carried out using this positioning data. (2-
axis interpolation control, and multiple axes using simultaneous start is
possible.)
2) Linear control (2-axis simultaneous execution possible) is possible with
positioning for each axis. This control can carry out independent
positioning with one positioning data item, or can carry out continuous
positioning with continuous execution of multiple positioning data items.
3) With multiple axes positioning, linear interpolation control or circular
interpolation control using two axes is possible. This control can carry
out independent positioning with one positioning data item, or can carry
out positioning with continuous execution of multiple positioning data
items.
(b) The control method designated with each positioning data includes position
control, speed control and speed/position changeover control.
(c) Continuous positioning with multiple positioning data items is possible with
the operation pattern set by the user using positioning data.
With the above multiple positioning data as one block, continuous
positioning of multiple blocks is possible.
