Operation principle
The actuator (in this case a DC motor) is regulated by the internal
logic. The required parameters are transferred from the higher
level controller (master) to the internal logic.
The product carries out a movement. Its position is checked
constantly. The parameters required for this are transmitted by
the sensors back to the internal logic.
The following parameters can be transferred from the overriding
control (master) to the internal logic:
• Current I
• Speed v
• Acceleration a
• Position
NOTE
All possible parameters and the special features of each
communication interface (of the individual bus systems) are
described in more detail in the document about SCHUNK Motion
Protocol, see DVD, document: MotionToolSchunk.pdf.
