Block schematics
The housed format contains two boards: the servo board and the power supply board. On the servo board, the
power part and the control part are galvanically separated. The inputs and outputs are insulated from the
control part by opto-couplers.
Caution:
The GND is internally connected to the DSC2P front panel which is connected to the
ground
(PE).
The power GND is not connected to the ground (PE).
