Abstract

In a customization method of a motor control device, a customization module for executing a modifying operation of a specific function in a customizing element is formed. A customization module group is configured by a set of customization modules. The user can form a user module for executing an operation related to the specific function in the customizing element. A buffer memory accessible from both the customization module and the user module is provided. The customization module is configured to execute the operation related to the specific function based on data received from the user module via the buffer memory.

Claims

1. A customization method of a motor control device for controlling a motor, the customization method achieving customization in the motor control device by providing a customizing element in each function unit for allowing a user to modify a specific function, the customization method comprising:

forming a customization module for executing a modifying operation of the specific function in the customizing element, and configuring a customization module group by a set of customization modules;

allowing the user to form a user module for executing an operation related to the specific function in the customizing element; and

providing a buffer memory accessible from the customization module and the user module,

wherein

the customization module is configured to execute the operation related to the specific function based on data received from the user module via the buffer memory.

2. The customization method of the motor control device of claim 1,

wherein

the user module is restricted to writing to the buffer memory only, and

the customization module is restricted to using data in the buffer memory as a parameter for executing an operation.

3. The customization method of the motor control device of claim 1,

wherein

the customization module executes the modifying operation according to a preinstalled procedure, and

the user module executes the operation related to the specific function according to a command procedure created by the user.

4. The customization method of the motor control device of claim 1, wherein the customization module is restricted to receiving data from the user module only via the buffer memory.

5. The customization method of the motor control device of claim 1,

wherein

the user module writes a segment number and a set value of the specific function to be modified to the buffer memory according to a command set by the user, and

the customization module refers to the segment number and the set value written to the buffer memory by the user module to execute the modifying operation of the specific function.

6. The customization method of the motor control device of claim 1, wherein the user module and the customization module are activated as mutually independent tasks.

7. A motor control device for controlling a motor, the motor control device having a customization function in which a plurality of customizing elements are provided in each function unit for allowing a user to modify a specific function, and comprising:

a CPU for executing processing according to a program;

a program memory storing a program including a motor control program for controlling a motion of the motor;

a drive circuit receiving a motor control signal generated by executing the motor control program by the CPU, and generating a motor drive signal for energizing and driving the motor based on the motor control signal;

a customization module memory storing a customization module group including a customization module for executing a modifying operation of the specific function in the customizing elements;

a user module memory storing a user module for executing an operation related to the specific function in the customizing elements, the user module being formed by the user; and

a buffer memory accessible from the customization module and the user module,

wherein

the customization module executes an operation based on data received from the user module via the buffer memory, so as to execute the customization function.

8. The motor control device of claim 7, wherein the user module writes to the buffer memory only, and the customization module executes an operation while using data in the buffer memory as a parameter, so as to execute the customization function.

9. The motor control device of claim 7,

wherein

the customization module executes the modifying operation according to a preinstalled procedure, and

the user module executes the operation related to the specific function according to a command procedure created by the user.

10. The motor control device of claim 7, wherein the customization module is restricted to receiving data from the user module only via the buffer memory.

11. The motor control device of claim 7,

wherein

the user module writes a segment number and a set value of the specific function to be modified to the buffer memory, according to a command set by the user, and

the customization module refers to the segment number and the set value written into the buffer memory by the user module to execute the modifying operation of the specific function.

12. The motor control device of claim 7, wherein the user module and the customization module are activated as mutually independent tasks.
