Please refer to the following table for the explanation of monitor variables:
Item
Variable Each monitor variable has one corresponding code. The parameter P0-02 is used to
Code set this code and monitor the monitor variable.
Format Each monitor variable is saved in 32-bit (long integer) in the servo drive.
There are two types of monitor variables, basic variable and extension variable:

Basic variable: Enter into monitor mode by pressing MODE key on the digital
keypad. In monitor mode, press UP/DOWN arrow keys to find the available
monitor variables (P0-02=0~26).
Extension variable: Other variables are called extension variables except basic
variables (P0-02=27~127).
LED display of digital keypad: Monitor the monitor variables through the LED
display of the digital keypad directly.
Mapping parameters: The settings of monitor variables will be reflected on the
setting value of the parameters. The users can know the settings of monitor
variables through the corresponding parameters.
Press MODE key to switch to monitor mode and then press UP/DOWN arrow
keys to select the desired monitor variables.
Set P0-02 directly and then display the settings of the desired monitor variables.

be set first to read the status value (see P0-02). When reading the drive status
through Modbus communication, the system will read the monitor status which
specified by P0-17. When reading the drive status through the keypad, if P0-02 is
set to 23, VAR-1 will quickly show for about two seconds and then the value of P0-
09 will display on the display.
