9.2.15 Position specified Speed/Position Switching Control
The setting axis carries out the speed control and is switched from speed control to position control when
position specified speed/position switching signal is entered to the positioning module, and then carries out the
positioning according to target position.
(1) Characteristics of Control
(a) Set control meth
od of operating data as “Single axis speed control” and execute
「

」
during speed control operation.
(b) In case of speed/position switching, this determines whether to consider the set position 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.
(c) In speed/position switching control, the value of coordinate specified when starting speed control has no
affection. In other words, action
of “Absolute, single axis speed control” and “incremental, single axis speed
control” are same.
(d) In Position specified speed/position control, a target position set in the operation data or Direct start
command is ignored and it moves according to target position operand of

command
(2) Operation timing
1) Speed/Position switching coordinate = 0: incremental
