<p>PURPOSE:To shorten a setting time and to prevent the generation of missetting at the time of setting up a parameter by using a writable/readable non-volatile memory, previosuly clearing the contents of the memory to mount the memory on a base part, and since a flag is off at the time of the application of a power source, automatically setting up the reference value of the parameter. CONSTITUTION:A printed board in which the contents of a parameter setting memory 5 are completely cleared in advance is mounted on the base part 1. When the main power unit 11 is connected, a parameter setting part 4 in the base part 1 reads out the contents of a flag area 6 in the memory 5. When the flag 20 is OFF, a reference value 21 is written in a parameter setting area 7 to turn on the flag 20, and when the flag 20 is ON, the processing is ended as it is. When the processing of the parameter setting part 4 is ended, an initializing part 3 starts its operation and initializes respective parts by referring the area 7. Since the parameter reference value 21 can be automatically set up by forming the flag area 6, previously clearing the contents of the area 6 and then mounting the area 6, the time for setting up the parameter can be shortened and the generation of missetting can be prevented.</p> |
