PURPOSE: A high pressure inverter controller is provided to store failure information in the central processing unit (CPU) failure by managing the failure information using an external memory. CONSTITUTION: An input and output part (104) inputs system voltage/current, motor voltage/current, and direct current (DC) link voltage to a first control part. The input and output part outputs a voltage command and status information which are applied from the first control part. A second control part (107) connects a parameter related to monitoring, control, diagnosis, establishment, and upgrade with a host system. A memory part (106) stores set and control values which are exchanged between the first control part and the second control part. A field bus side board part (111) provides a side board which is converted into various field buses to the second control part.
