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
