[Problems to be solved by the invention]
However, in the conventional parameter display method, in the case of Patent Document 1, the genre is not the display of a recent drive device (servo driver) but the display of an inverter device only. The one that was displayed alternately by switching different parameters has been improved so that it can be used as a monitor during operation by adding a level meter so that both can be monitored simultaneously with a simple display. Is also a percentage display based on the position of the LED, and there is a problem that numerical values are not displayed accurately.
In addition, in the case of a servo driver mainly used for setup before operation, it is an accurate numerical display for control, but since the numerical value is directly connected to the physical quantity, the numerical value is too large If it is too small, there may be a problem that it cannot be displayed well on a display device with a limited number of digits, and it is difficult for non-specialists to perceive what kind of numerical change is allowed There was such a problem.
The present invention has been made in view of such a problem, and enables the display of the same parameter to be switched to a display using a different expression to solve the problem that a numerical value cannot be displayed. It is another object of the present invention to provide a method that can intuitively change a numerical value.
[0005]
[Means for Solving the Problems]
In order to solve the above problem, an invention according to claim 1 is a method for displaying a parameter of a drive device having a function of displaying and editing a parameter, wherein a parameter default value is set to 100% and the value is displayed and edited as a percentage. It has a method and a method of displaying and editing parameter values in the physical quantity, and is characterized by switching between the two display and editing methods.
According to a second aspect of the present invention, in the display method according to the first aspect, the percentage display method displays and edits a difference from a standard value as a percentage by setting a default value to 0%. .
According to a third aspect of the present invention, in the display method according to the second aspect, when the percentage display method changes the same percentage value in consideration of a required increase / decrease amount of a plurality of parameters, a necessary change is obtained. It is characterized by setting the value scale factor so that it can be used.
According to the parameter display method of the drive device, the parameter display is switched between a display based on a physical quantity and a display based on a percentage, and the numerical value is too large or too small by appropriately determining a factor of the change amount. In this case, it is possible to solve the problem that the display cannot be performed well with a display device having a limited number of digits, and it is possible to provide an operation environment in which the operator can comfortably change the numerical value.
