Comay controller AMF25 MRS10 controller sub-assemblies and micro-program controller logic controllers both controllers have strengths and weaknesses. Combinational logic controller design problems, complex structure, once the design is complete, you can not modify or expand, but it's fast. Micro-program controller to facilitate the design, simple structure, easy to modify or expand both the regulator board sx440 production, modify the function of a machine instruction generator SX440 manufacturers simply restated the corresponding micro-program; to add a machine instruction, just increase in the control section of the microprogram memory, but Dongguan generator SX440, it is by executing a microprogram. Specific comparison is as follows: a combination of hardwired controller logic controller, also known by the logic circuit SX440, relies entirely on the hardware to achieve command functions. When the electric car brushless controller phase brushless electric vehicle controller power and brake failure may refer to brush failed controller troubleshooting be thoroughly excluded in terms of brushless controller, as well as its unique Symptom such phase. Phase brushless electric vehicle controller phenomenon can be divided into the main phase and phase Hall phase two cases. 1) The main phase missing phase detection method can refer to the electric car brush controller Speed ??troubleshooting method to detect whether the MOS transistor breakdown, brushless controller MOS tube down the breakdown is generally one of a pair of phase two MOS tube Meanwhile breakdown, while ensuring at the same time to replace the replacement. Check the measuring points. 2) brushless electric vehicle controller Hall performance phase motor controller does not recognize the Hall signal.
