PURPOSE:To prevent parameters which are adjusted and set from being changed by mistake and to improve safety by setting a password when setting protection to the parameters and then constituting so that the protection cannot be canceled without using the password. CONSTITUTION:In an operation mode of a parameter setting part 3, a variety of parameters including set-up parameters and user parameters are set collectively. Then, in an operation mode of a protection setting part 7, parameter change protection can be set by inputting a password from a password setting part 5. Furthermore, when the input password agrees with the password which is stored by the protection setting part 7 in the operation mode of a protection cancellation part 9, the protection is canceled and the parameters can be changed, thus enabling only a specific person to change the parameters which are protected by a password. |
