9.2.14 Speed/Position Switching Control
The setting axis carries out the speed control and is switched from speed control to position control when
speed/position switching signal is entered to the positioning module inside or outside, and then carries out the
positioning according to the target position.
(1) Characteristics of Control
(a) Set control metho
d of operating data as “Single-axis speed control” and execute
「
Speed/Position
Switching
」
command during speed control operation.
(b) Direction of movement depends on the sign of value.
■ Forward: The position value is Po)
■ Reverse: The position value is Negative(-)
(c)
On order to use the external command as “Speed/position switching signal”, you have to set “External
command selection” item and “External command” item of extended parameter.
Item Setting value Description
External command
selection
0 : External
speed/position control
switching
In case there is external command input, it is used
as “External speed/position control switching” signal
1 : External stop
command In case there is external command input, it is used
as “External stop command” signal
External command
0: Disable
External command signal is ignored and it does not
affect operation
1: Enable
In case there is external command input, it operates
according to “External command selection” item.
(d) In case of speed/position switching, this item determines whether to consider the set value as absolute
coordinate value or incremental coordinate value.
Item Setting value Description
Speed/position
switching coordinate
0 : incremental
The object moves as far as the set value from the position
where command is executed.
1 : absolute
It considers the set value as the absolute coordinate value
and the object moves to the set absolute position.
(e) The coordinate setting specified
when starting the speed control doesn‟t affect the operation. Namely,
operation
of “ABS, single-axis speed control” is same as that of “INC, single-axis speed control”.
