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:

providing 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, the customization module including one or more programs that are not editable by the user;

allowing the user to create a user module for executing an operation related to the specific function in the customizing element, the user module including one or more programs created by the user; and

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

the motor control device includes a CPU,

the CPU reads the user module and writes the one or more programs created by user to the buffer memory, and

then, the CPU refers to the one or more programs created by user stored in the buffer memory and executes the specific function stored in the customization module based on the one or more programs created by user stored in the buffer memory.

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

the CPU executes the operation of the specific function only based on the one or more programs created by user stored in the buffer memory.

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

the CPU executes the modifying operation according to a preinstalled procedure of the one or more programs of the customization module, and

the CPU executes the operation related to the specific function according to a command procedure of the one or more programs created by the user.

4. The customization method of the motor control device of claim 1, wherein:

the data include a segment number and a set value of the specific function to be modified according to the one or more programs created by the user, and

the CPU refers to the segment number and the set value written to the buffer memory to execute the modifying operation of the specific function.

5. The customization method of the motor control device of claim 1, wherein the CPU activates the user module and the customization module as mutually independent tasks.

6. 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 the motor control device comprising:

a CPU for executing processing according to a program;

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

a drive circuit for 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 a specific function in the customizing elements, the customization module including one or more programs that are not editable by the user;

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, the user module including one or more programs created by the user; and

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

the CPU is configured to read the user module memory and write the user module to the buffer memory, then, refer to the user module stored in the buffer memory, and execute the specific function stored in the customization module memory based on the user module stored in the buffer memory, and

the buffer memory is configurated to be only written the user module and to be only read the user module by the CPU.

7. The motor control device of claim 6, wherein:

the CPU executes the specific function based on the user module.

8. The motor control device of claim 6, wherein:

the CPU executes the modifying operation according to a preinstalled procedure of the one or more programs of the customization module, and

the CPU executes the operation related to the specific function according to a command procedure of the one or more programs created by the user in the user module.

9. The motor control device of claim 6, wherein:

the user module memory stores a segment number and a set value of the specific function to be modified according to the one or more programs created by the user, and

the CPU refers to the segment number and the set value and the modifying operation of the specific function based on the segment number and the set value.

10. The motor control device of claim 6, wherein the CPU activates the user module and the customization module as mutually independent tasks.

11. The motor control device of claim 6, further comprising:

a control parameter memory stored a parameter based on the user module from the customization module,

wherein the motor control program obtains the parameter from the control parameter memory.

12. The motor control device of claim 6, wherein the user module including a plurality of programs created by the user,

wherein all the plurality of programs are sent from the user module memory to the customization module memory via the buffer memory.
