In addition to the standard application macro program, users can also define two user macros themselves. User macros allow users to store parameters
Number setting value (including parameter group 99) and motor identification data. These values are stored in permanent memory regardless of the power supply
Whether it is closed or not will not be lost. In the future, users can call these data as needed. Similarly, it can also store and control
Disk setting value and control setting value (local or remote).
Define user macro 1:
• Adjust parameter settings. Perform motor identification (if not already done).
• Set the value of parameter 99.02 to USER 1 SAVE and press ENTER. The current parameter settings can be saved
And motor identification results. The storage time is 20 s~1 min.
Note: If the macro saving function of the user is executed for many times, the memory of the transmission unit is filled and the file compression function is started. writing
The file compression lasts for 10 minutes. After the file compression is completed, macro saving will be completed. (The operation will be carried out at the top of the control panel
The latter is arranged and displayed by flash point)
Call user macro program:
• Change the value of parameter 99.02 to USER 1 LOAD.
• Press ENTER to call.
The user macro can be switched through the digital input port (see parameter 16.05).
Note: When calling the user macro program, the program will also restore the settings in parameter group 99 START-UP DATA to
And the results of motor identification. Before use, check whether the setting value conforms to the data of the motor used.
For example, instead of adjusting motor parameters and repeatedly performing motor identification every time, users can use one transmission to
Switching between motors. Users only need to operate two motors once, and identify their parameter values and motors
The data is stored in two user macros. When the motor changes, just call the corresponding user macro.
