3.6.7 Position/Simplified Direct Value Mode2 (Number of Occupied Bytes: 8)
In this mode, the actuator is operated by means of force control (pressing operation based on feedback of
load cell values) and also by specifying position numbers. Whether the target position is set directly the
control signals (PMOD signals), or the value registered on the position data is used can be selected.
For the speed, acceleration/deceleration and positioning band, etc., except for the target position, the
values in the position table within the controller are used. Setup the position data referring the operation
manual for the controller main body.
The settable No. of position data items is max 768 points.
The robot cylinder's effective main functions that can be controlled using this mode, are as shown in the
following table.
