PURPOSE:To prevent generation of a setting error by selecting a data within a setting range calculated in advance and inputted the result in inputting various setting values required for the control operation to a controller. CONSTITUTION:A setting data fetched to a key input section 2 by the key operation is stored in a temporary storage section 6. Then various setting values stored in a setting value storage section 10 by a command of a control section 5 and setting data to be set and stored tentatively in the storage section 6 while being fetched by key input are sent to an arithmetic section, where the arithmetic operation is performed, resulting that when the setting value to be set at present is within the setting range, the value is sent to a display section 9 via the storage section 6 and the value is displayed on a display device. If the setting value to be set at present is out of the setting range, the arithmetic section 7 selects a data within the setting range closest to the setting value going to be set and the value is displayed on the display section 9 through the storage section 6. |
