Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting method for setting and controlling various control parameters of a servo motor control system in a servo motor driving servo amplifier or a setting section of a loader separately provided from the servo amplifier.

[0002]

2. Description of the Related Art FIG. 5 is an example of a system configuration diagram of a servo motor control system using a servo amplifier. As a conventional parameter setting method of this type, various control parameters are displayed in a parameter display section shown in the system configuration diagram. Figure 6
It is known to display as shown in the parameter display state diagram of FIG. Note that FIG. 7 is a control system operation mode display state diagram on the display unit.

In FIG. 5, reference numeral 1 denotes a servo amplifier, which internally has a storage section for various control parameters of the servo motor control system, and the storage content of this parameter is called and displayed on 11 parameter display sections. Is. Reference numeral 2 is a servo motor which is driven and controlled by the servo amplifier 1. A loader 3 has a parameter display unit 31 and a setting unit equipped with various operation keys, which is usually provided separately from the servo amplifier 1, but is detachably attached to the servo amplifier 1 if necessary. This is for setting or changing parameters in the parameter storage section of the amplifier and displaying the result.

6 and 7 show examples of display on the parameter display section 31 of the loader 3, and FIG. 6 shows the second parameter mode (P) from each mode (MODE) shown in FIG.
The display state of each parameter when A) is selected is shown. Here, numbers 1 to 99 are assigned to the respective parameters, and one to several of them are displayed in the order of the assigned numbers. FIG. 6 shows a state in which three types of parameters, numbered 7 to 9, are displayed.

[0005]

However, the conventional parameter setting method as described above has the following problems. 1) At the time of a parameter changing operation, there is a risk that it may not be clear what the displayed parameter is for or a misunderstanding just by looking at the parameter display section.

2) At the time of changing the parameters, it is not clear whether the displayed parameters are changed from their initial values or there is a risk of misunderstanding just by looking at the parameter display section. 3) There are many parameters to be used, for example, numbers 1 to 99, and only a few of them are sequentially displayed on the parameter display section. Therefore, when only the parameters changed from the initial values are changed again, the operability is not good.

4) During the parameter initialization operation, the fourth reset mode (RES) shown in FIG. 7 is selected and initialized. This mode initializes all parameters, and some parameters are initialized. There is a difficulty in the operability for only initialization. Note that the initialization means setting the set value of the target parameter as its initial value, and this initial value is assumed in advance as a value suitable for this control system prior to actual operation of the servo motor control system. It is the value.

In view of the above, the present invention has an object of providing a parameter setting method for improving the operability at the time of parameter changing operation by mainly changing the display contents of the parameter display section mainly in software. is there.

[0009]

In order to achieve the above object, in the parameter setting method of the present invention, 1) As its first means, various control parameters of the servo motor control system are set to servo motor drive servo. In the parameter setting method of setting operation in the setting section of the amplifier or any of the loader separately provided, an operation button for displaying the contents of each of the parameters is provided in the setting section of the servo amplifier or loader, and during operation of this button The description of each parameter is sequentially displayed on the display section of the servo amplifier or the loader. 2) As the second means, various parameters for controlling the servo motor control system are set to servo amplifiers for driving the servo motor or In the parameter setting method for setting operation in either the setting unit of this loader If the parameter called and displayed on the display unit of the servo amplifier or loader is different from its initial value, this parameter is displayed with a predetermined mark, and 3) the third means. As a parameter setting method for setting and controlling various control parameters of the servo motor control system in a servo motor driving servo amplifier or in a setting section of the loader installed separately from the servo amplifier, in the display section of the servo amplifier or loader, A mode for sequentially selecting and displaying only the parameters different from the initial value shall be provided, and 4) As a fourth means, the control parameters of the servo motor control system may be set in the servo amplifier for driving the servo motor or separately. In the parameter setting method in which the setting operation is performed in either setting section of the loader, Pump or provided parameters initialization operation button setting section of the loader, by operation of the button, it is assumed that to perform the initialization only any one parameter of.

[0010]

The present invention adds the following respective functions for the parameter setting operation by taking measures on software. That is, 1) While the parameter content display button is being operated, the content description of each parameter is sequentially displayed on the parameter display section.

2) Of the parameters called and displayed in the parameter display section, those having different initial values are given a predetermined mark. 3) In addition to a mode in which each parameter is sequentially called and displayed in the order of its number, a mode in which only parameters different from their initial values are selectively displayed is provided. 4) Initialize only one parameter specified by operating the parameter initialization button.
