Selection of the valve control
If the direction valves should be controlled via the servo drive, the following three
modes are available. In addition, the respective digital outputs on the servo drive
must be assigned to the correct function. For the direction valves, HYD_CYL_POS
(76) and HYD_CYL_NEG(77) must be selected. Optionally, two further valves can be
controlled depending on the hydraulic setpoint table (HYD_VAL_OPT1(74) and
HYD_VAL_OPT2(75)).

5, etc.)
l
1 = not defined
l
2 = Tab
Valve switching via the motion block table; for each motion block, one valve
position can be specified which becomes active when the respective motion
block is called.
l
3 = Pos
Automatic valve switchover via position difference. Depending on the
position task, the valve is switched for a positive or negative operating
direction.
Once the position window has been reached (
P 2870.0 - PosWindowLo
;
P 2870.1 - PosWindowUp
), the valves are switched off and the cylinder is
tensioned. For the control mode SpdCon(2), the valves are switched in
dependence on the sign of the cylinder speed.

7 Control
For communication with a higher-level controller in the CTRL1 and CTRL2 operating
modes, some scaling factors of process variables and control parameters are
summarized in P 2879 HYD_AddProcData. These parameters are PDO-capable
and are created in the int16 format in order to use as little memory space as possible
in the process data channel. The unit of the parameters is per mill. The value 1000
therefore corresponds to 100%.
