Chapter 7 Motion Control Functions
System Parameters Monitor Parameters
Remark -
In monitor mode, users can press UP or
DOWN arrow key to change the
monitoring variables (monitor item
settings) in common use (code 0 ~ 26).
Please note that not all monitoring
variables can be displayed (total 150
kinds of monitor parameters).
7.2.1 Monitoring Variables
Please refer to the following table for the explanation of monitoring variables:
Item Explanation
Code
Each monitoring variable has one corresponding code. Using the parameter
P0-02 is able to set this code and perform status monitoring.
Format Each monitoring variable is saved in 32-bit (long integer) in the servo drive.
Type
There are two types of monitoring variables, basic monitoring variables and
extension monitoring variables:
1. Basic monitoring variables: Enter into the monitor mode by pressing
MODE key on the digital keypad. In monitor mode, press UP/DOWN arrow
keys to find the available basic monitoring variables (P0-02=0~26).
2. Extension monitoring variables: Other monitoring variables are called
extension monitoring variables except basic monitoring variables (P0-
02=27~127).
Monitor
Method
There are two methods for status monitoring. One is through LED display of
the digital keypad and the other is via the mapping parameters:
1. LED display of digital keypad: Status monitoring through the LED display
of the digital keypad directly.
2. Mapping parameters: The settings of the monitoring variables will be
reflected on the setting value of the mapping parameters. Users can
know the settings of the monitoring variables through the corresponding
parameters.
Display
1. Press MODE key to switch the monitor mode and then press UP/DOWN
arrow keys to select the desired monitoring variables.
2. Set P0-02 directly and then display the settings of the desired monitoring
variables.
Press SHIFT key to switch high/low byte display;
Press SET key to switch decimal/hexadecimal display.
Mapping
Function
1. The parameters which support mapping function includes: P0-09 ~ P0-13.
(Please refer to section 8.3 “Detailed Parameter Listings” of Chapter 8.
2. Using mapping parameters and read & write monitor parameters through
communication.
3. The setting values of P0-09 ~ P0-13 (Status Monitor 1 ~ 5) are the content
of basic monitoring variables (17h,18h,19h,1Ah). When users want to
monitor P0-09, set P0-17 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.
