[0004] A first aspect of the present disclosure is a setting method for setting specification information in a drive unit that drives an electric actuator, the setting method including: an acquisition step in which, when the electric actuator is connected to the drive unit, an acquisition unit acquires the specification information corresponding to the connected electric actuator from a specification information storage unit that stores the specification information, which is information regarding the specifications of the electric actuator; and a setting step in which a setting unit sets the specification information acquired by the acquisition unit in the drive unit.

[0010] A seventh aspect of the present disclosure is an electric actuator in the drive system of the fourth aspect, wherein the electric actuator includes the specification information storage unit.

[0011] The present invention can provide a better setting method, a program, a computer-readable non-transitory storage medium, a drive system, a setting device, a drive device, and an electric actuator.

[0012] The above objects, features and advantages will be easily understood from the following description of the embodiments, which will be described with reference to the accompanying drawings.

[0013] FIG. 1 is a schematic diagram of a drive system according to a first embodiment. FIG. 2 is a block diagram of an electric actuator according to the first embodiment. FIG. 3 is a block diagram of a drive unit according to the first embodiment. FIG. 4 is a block diagram of a setting device according to the first embodiment. FIG. 5 is a flowchart showing specification information setting processing performed in the setting device according to the first embodiment. FIG. 6 is a block diagram of a drive unit according to a second embodiment. FIG. 7 is a flowchart showing specification information setting processing performed in the drive unit according to the second embodiment. FIG. 8 is a block diagram of an electric actuator according to a third embodiment. FIG. 9 is a block diagram of a drive unit according to the third embodiment. FIG. 10 is a flowchart showing specification information setting processing performed in the drive unit according to the third embodiment.

[0014] There are various types of electric actuators, including slider type, rod type, rotary table, etc. For example, in a slider type electric actuator, the rotational motion of an electric motor is converted into linear motion by a linear motion mechanism, and the slide table moves along a linear guide.

[0015] Specifications for electric actuators are determined for each model of electric actuator. Information regarding the specifications of an electric actuator is necessary to operate the electric actuator and is managed as specification information. Examples of the specifications of an electric actuator include the minimum and maximum speeds that can be set for the electric actuator. The specifications differ depending on the model of the electric actuator.

[0016] The electric actuator is connected to a drive unit and is driven based on a drive signal sent from the drive unit. The drive unit has multiple ports, each of which is connected to one electric actuator. The drive unit has specification information for each electric actuator set for each port.

[0017] Typically, the model of the electric actuator to be connected to a drive unit is predetermined, and therefore, the specification information of the electric actuator to be connected to the drive unit is set in the drive unit when the drive unit is shipped from the manufacturer.

[0018] On the other hand, in order to increase the versatility of the drive unit, the manufacturer may ship the drive unit without setting any specification information in the drive unit. Such a drive unit is called a blank controller. When an electric actuator is connected to a drive unit that is a blank controller, the user must set the specification information of the electric actuator to be connected to the drive unit in the drive unit.

[0019] However, if the user sets incorrect specification information in the drive device, there is a risk that malfunctions will occur in the drive device and the electric actuator.

[0020] In the present disclosure, specification information of an electric actuator connected to a drive device is automatically set in the drive device, thereby reducing malfunctions in the drive device and the electric actuator.

The electric actuator 12 converts the rotational motion of the electric motor 18 into linear motion using a linear motion mechanism (not shown), and moves the slide table 20 along the linear guide 22. The type of electric actuator 12 is not limited to a slider type, and may be another type such as a rod type or a rotary table.

[0023] The driving device 14 has a plurality of ports 24. One electric actuator 12 can be connected to each port 24. The driving device 14 drives the electric actuator 12 connected to each port 24 based on a ladder program or the like created by the user. The driving device 14 may be a device having one port 24.

[0024] The setting device 16 is, for example, a personal computer. Setting software is installed in the setting device 16. The setting software sets the specification information of the electric actuator 12 in the drive unit 14. The setting device 16 is connected to the drive unit 14 when the specification information of the electric actuator 12 is set in the drive unit 14. Other components may be included between the drive unit 14 and the setting device 16.

A unique number is assigned to each individual electric actuator 12 as the unique identification information. The unique identification information may include letters, symbols, etc. in addition to numbers. The model identification information is, for example, the model number (model name, product model number) of the electric actuator 12. A unique number is assigned to each model of electric actuator 12 as the model identification information. The model identification information may include letters, symbols, etc. in addition to numbers.
