BACKGROUND OF THE INVENTION
The present invention relates to a parameter display method for a drive device having a parameter display and editing function, and an apparatus therefor .
[0002]
[Prior art]
As an example of a conventional drive device, there is a “display device of an inverter device” disclosed in Patent Document 1. FIG. 8 is a front view of a display device of a conventional inverter device. The display 40 switches and displays the frequency and current value of the inverter for variable speed control of the AC motor, and the current frequency with respect to the maximum set value of the frequency. It is comprised with the level meter 50 which displays a ratio. The level meter 50 has a plurality of LEDs 51 arranged obliquely upward to the right, and the ratio of the current frequency to the maximum set value is displayed according to the number of lighting. As a result, even if the current value is displayed on the display 40, the frequency can be monitored simultaneously.
Patent Document 1 relates to an inverter device. Recently, a servo driver and an inverter device integrated servo driver as a drive device (for example, a servo driver SGDH type in which an encoder / feedback signal is increased to about 16 Mpps). (Product name) is equivalent) in many cases, and the parameter display in this case is generally performed by the physical quantity. For example, the parameter Pn100 is a speed loop gain. If the value is 40, it means a physical quantity of 40 Hz as it is. The display is common.

[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 related to the display of the recent drive device (servo driver) but is related to the display of the inverter device, and the two are frequency and current value. What was displayed alternately by switching different parameters has been improved so that both can be monitored at the same time by adding a level meter and using it as a monitor during operation. The percentage display is also a percentage display based on the position of the LED, and there is a problem that the numerical display is not accurate.
In the case of a servo driver used mainly for setup before operation, although it is an accurate numerical display for control, the numerical value is too large because it is directly linked to the physical quantity. 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 also difficult for a non-specialist to know what numerical values are allowed to change. 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 the display by different expressions, solves the problem of not being able to display numerical values, and is not an expert. However, the object is to provide a method capable of intuitively changing numerical values.
[0005]
[Means for Solving the Problems]
In order to solve the above problem, the invention according to claim 1 is a parameter display method for a drive device having a parameter display and edit function, wherein the default value of the parameter is set to 100%, and the value is displayed and edited as a percentage. A method and a method of displaying / editing parameter values with their physics quantities, and switching between the two display / editing methods.
Further, in a parameter display device for a drive device having a parameter display and editing function, the default value of the parameter is set to 100%, the means for displaying / editing the value in percent, and the parameter value is displayed in its physical quantity. And a means for editing, and switching between the two display / editing means.
According to the parameter display method of this drive device, the parameter display is switched between the physical display and the percentage display, and the numerical value is too large or too small by appropriately determining the change factor. In this case, it is possible to solve the problem that display cannot be performed well on a display device with a limited number of digits, and it is possible to provide an operating environment in which the operator can comfortably change numerical values.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration for demonstrating the parameter display method of the drive device according to the first embodiment of the present invention.
FIG. 2 is a diagram showing a percentage display example of the parameters of the drive device shown in FIG.
FIG. 3 is a diagram showing a display example when the display of FIG. 2 is switched to a physical quantity. In FIG. 1, reference numeral 1 denotes a parameter value holding unit, which holds a physical quantity of parameters. A data conversion unit 2 converts the physics of the parameter into a percentage value. 3 is a switching unit that determines whether to display a physical quantity or a percentage value, and 4 is a display device.
[0007]
Next, the operation will be described.
In FIG. 2, the parameter value is currently 100 percent. FIG. 3 is a display example when the display of FIG. 2 is switched to physics, and in FIG. 3, the parameter value is currently 40, which is the standard value of this parameter. In FIG. 2, an increase / decrease of 1 percent corresponds to an increase / decrease of 0.4 in FIG. This first embodiment relates to claim 1.
[0008]
Next, Reference Example 1 of the present invention will be described with reference to the drawings.
FIG. 4 is a view showing a parameter percentage display example of the drive device according to Reference Example 1 of the present invention.
In this case, the default value is set to 0%, and if this is the same as that shown in FIG. 3 when switched to the physical quantity display, the percentage display when the physical quantity is 40 is 0%. It can be arbitrarily determined how much the 1% increase or decrease corresponds to the physical quantity. This method has an advantage that the percentage display is possible even when the standard value of the physical quantity of the parameter is zero .
[0009]
Next, Reference Example 2 of the present invention will be described with reference to the drawings.
FIG. 5 is a diagram showing a parameter display example of the drive device according to Reference Example 2 of the present invention.
FIG. 6 is a diagram showing a display example when the parameter values shown in FIG. 5 are changed.
FIG. 7 is a diagram showing a percentage display example of the parameters shown in FIG.
For example, when two parameters representing a speed loop gain and a speed loop integration time constant are considered, considering a physical quantity, for example, when the speed loop gain is increased from 40 to 60, a speed loop integration time constant (calculation formula) Reference) should be reduced from 16 to 11.
FIG. 5 shows parameter values before change. 5 represents a speed loop gain, and 6 represents a speed loop integration time constant. FIG. 6 shows the parameter values after the change. In FIG. 6, 7 represents a speed loop gain, and 8 represents a speed loop integration time constant. When expressed in terms of physics, increasing the speed loop gain requires a decrease in the speed loop integration time constant, which can be confusing for non-specialists. FIG. 7 shows an example in which the parameter values in FIG. 6 are displayed as percentages after correcting the change / increase / decrease in the values. In FIG. 7, 9 represents a speed loop gain, and 10 represents a speed loop integration time constant. By doing so, even a non-specialist who cannot directly understand the physical quantity can change the parameter numerical values accurately and comfortably .
