(2) Ease of compatibility with absolute position detection system
(a) Connection of an absolute position corresponding servo system supports
an absolute position detection system.
(b) Once a zero point position is established, zero point return operation is not
necessary at power-on.
(c) In the absolute position detection system, a zero point position can be
established by a data setting method machine zero point return.
This eliminates the need for wiring of near-point dogs, etc.
(d) By setting the absolute position restoration mode to the "infinite length
mode", infinite length positioning control in the control unit "degree" can be
realized in the absolute position detection system.
(3) Control by machine system input
External inputs, such as the external start, stop and speed/position changeover,
enable positioning control without use of sequence programs.
(4) Lineup of 1-axis to 3-axis modules
(a) There are six types of positioning modules for 1-axis to 3-axis control.
Select according to the PLC CPU type and the required No. of control axes.
(b) There is one slot used to mount each AD75 onto the base unit. The number
of input/output points occupied by the PLC CPU is 32 points each.
There is no limit to the No. of mounted modules as long as the total is within
the PLC CPU No. of input/output points.
(5) 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 (3-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.
