Revision February, 2017     7-1 
Chapter 7 Motion Control 
7.1  Motion Control Functions of ASDA-A2 
1) Single-axis motion controller of PR (Procedure) control 
2) Function of Capture (data capture) / Compare (data compare) 
3) Electronic Cam (E-Cam) function (ASDA-A2 series L type models do not provide this function.)
 
 
7.2 System Information  
The information of the servo drive can be divided into three parts: System parameters, Monitoring 
variables and Data array. 
Descriptions are as follows: 
 
  System Parameters  Monitoring variables 
Functional 
Description 
It is used to be the reference mode, 
important data or operation condition 
when the servo drive is operating, 
e.g. Control Mode, Servo Loop Gain, 
etc. 
The status of the servo drive or motor,  
e.g. motor position, speed, electric  
current, etc. 
Display Format 
Panel displays PX-XX. 
Pressing the SET Key to display 
parameters and start setting.  
Please refer to Chapter 4 for Panel 
Display and Operation. 
Set P0-02 to Monitoring variables code 
and enter into Monitor Mode. The panel 
will display the value of the variable. 
Or pressing the MODE Key on the 
panel to switch to Monitor Mode.  
Please refer to Chapter 4 for Panel 
Display and Operation. 
Access Method 
Readable and writable (depends on 
parameters) 
Read-only 
Data Size 
16-bit or 32-bit (depends on 
parameters) 
32-bit integers only 
Communication 
Access via MODBUS / CANopen / 
USB 
Each parameter occupies two  
MODBUS addresses 
  It only can be monitored via PC  
software by connecting USB 
  It does not directly support 
MODBUS / CANopen access, 
unless mapping is for corresponding 
the specified monitoring variables to 
system parameters. 
Mapping 
Support 
8 groups of parameter, P0-25 ~ P0-
32 
(set by P0-35 ~ P0-42) 
5 groups of parameter, P0-09 ~ P0-13 
(set by P0-17 ~ P0-21) 
Note  
In Monitor Mode, pressing UP/DOWN 
Key on the panel to switch the 
commonly used monitoring variables
