Maserati GranCabrio
Body
DC-motors The NCP controls the DC-motor of each rear window lifter. The opening/closing movement of the window lifters is managed by inverting the polarity of the DC-motor. When the window lifter reaches its end position, the increased current draw as a result of the increased mechanical resistance enables the NCP to deactivate the DC-motor. By this way there is no need to use traditional end-of-run micro switches. The front latch mechanism locks the roof to the windscreen frame. The front latch motor is operated by a relay which is integrated inside the NCP. The motor of the electric pump of the roof hydraulic system is controlled directly by the NCP by means of an integrated relay. No external relay is used. Each DC-motor output of the NCP is protected against short circuits. It uses voltage feedback to detect error situations and a shunt resistor to measure each motor current draw.
Solenoid valves The NCP activates three solenoid valves, which control the direction and functionality of the roof hydraulic system. The solenoid valves are integrated in the hydraulic unit.
