7.11.6.3 Hydraulic motion block table
The motion block table contains 16 motion blocks which can be parametrized (Index
0 to 15). The control mode, reference values and ramps as well as the valve
positions and switching conditions can be specified in each motion block.
If the servo drive is to be used as a stand-alone device, it is possible to set up a type
of sequence control using the motion block table. To activate the transition of the
motion block via the motion block table, the operating mode Tab(2) must be selected
in the motion profile P 2862[0] - HYD_OpMode. This allows switching between the
motion blocks to be control by either timing or an event. This function is enabled in
the Tab(2) operation mode.
As an option, it is also possible to use operation mode CTRL2 to switch the motion
blocks via a higher-order control system. These can be configured in advance for
different control tasks so that during the process only setpoints and the respective
table index must be selected or specified by the control system.
