User Variables and User Parameters

The following variables are provided for creating programs: User parameter variables, internal user
variables, and internal user contacts.
Use these variables for the program user interface, initial data for calculation, data saving during calcu-
lation, data saving, etc.
User Parameter Variables U(00) to U(63)
The DriveProgramming user parameter variables U(00) to U(63) are the unsigned 1-word variables.
The DriveProgramming user parameters U00 to U63 (UE-10 to UE-73) for the inverter correspond to
the DriveProgramming user parameter variables U(00) to U(63), respectively. Use these variables for
the following applications.

(corresponding to UE-10 to UE-73)
• The data of the parameters UE-10 to UE-73 saved in the EEPROM are automatically set to the user
parameter variables U(00) to U(63) when the power is turned on.
• By monitoring the parameters UE-10 to UE-73, you can check the data of the user parameter vari-
ables U(00) to U(63) after the program execution is started. Note that the data displayed on the LCD
Operator is the data at the moment when it is displayed. To update the data, once display the param-
eter number and then display the data again.
• When you change the parameters UE-10 to UE-73 by the LCD Operator and press the Enter key, the
changed data is saved in the EEPROM and reflected in the current user parameter variables U(00) to
U(63). The data saved in the EEPROM is set to the variables U(00) to U(63) automatically when the
power supply is turned on again.
• Even if the data of the user parameter variables U(00) to U(63) is changed in the program, the parame-
ters UE-10 to UE-73 is not saved in EEPROM.
Precautions for Correct Use
When the DriveProgramming program is stopped, the data of the user parameter variables
before the program stop is retained. When the program execution is started again, the process
begins with the retained data.
5 - 2
Use the variables as parameters to adjust calculation results. You can adjust
them using the inverter parameters (UE-10 to UE-73) according to the status
of application.
You can use the user parameter variables U(00) to U(63) as the variables for
calculation. The data of parameters UE-10 to UE-73 saved in the EEPROM
can be used as the initial data for calculation.
You can use the variables for saving data temporarily while the calculation is
in progress.
