F-GND (P-GND) : The motor system ground and the heat sink. Since the heat generated Since the heat generated by the
chip is dissipated through F-GND, the thermal resistance is lowered by increasing the area of the copper
foil and solder surface in the printed circuit pattern.
S-GND :
Control system ground
