4.4.4 Input and output signals for motion blocks
The controller enables the execution of individual orders, repetition of motion blocks
and automatic sequence of motion blocks.
The motion block for the motion order can be selected via digital inputs or parame-
ters. The terminal assignment (without selection of motion block) is shown in the
following table.
