3.6.8 Half Direct Value Mode 2 (Number of Occupied Bytes: 16)
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 the target position, positioning band, speed,
acceleration/deceleration and pressing current directly as numerical values. Set each value in the I/O areas.
When the zone function is used, set it using the parameter Nos. 1, 2, 23 and 24.
The robot cylinder's effective main functions that can be controlled using this mode, are as shown in the
following table.
