4.7.4 Half Direct Mode (Number of Occupied Channels: 8)
In this mode, the target position, positioning band, speed, acceleration/deceleration and push-motion current are
specified directly and numerically from the PLC.
Set each value in the I/O areas. To use the zone function, set appropriate values in parameter Nos. 1, 2, 23 and
24.
The key ROBO Cylinder functions that can be controlled in this mode are summarized in the table below.
