Abstract： Aiming at solving problems that the frequency conversion control system in the design，installation of the existence of such component layout unreasonable，conductor arrangement is not standardized，poor ventilation and other phenomena，which leads to the frequency conversion control system instability，failure and downtime， the inverter control system theory，design，component mounting and arrangement were explored，mainly the converter ventilation path selection，heat dissipation problems were analyzed. The method to solve the unstabitily of frequency control system was put forward. Practice running result shows that，according to this method，the installation of frequency converter control system fault rate is reduced，it greatly improves the stability.
