Chapter 6  Control Mode of Operation  ASDA-A2 
6-32     Revision February, 2017 
Manual: All parameters are set by users and the auto or auxiliary function will be disabled in this 
mode. 
Auto: General load inertia estimation is provided. It adjusts the parameter automatically. Its 
framework is divided into PI auto gain adjustment and PDFF auto gain adjustment. 
 
Parameter P2-32 can be used to adjust the gain.

Relevant description of manual mode setting: 
When P2-32 is set to 0, parameters related to gain control, such as P2-
00, P2-02, P2-04, P2-06, P2-07, P2-25 and P2-26, all can be set by 
the user. 
When switching mode from auto or semi-auto to manual, parameters 
about gain will be updated automatically. 
 
Relevant description of auto mode setting: 
Continue to estimate the system inertia, save the inertia ratio to P1-37 
every 30 minutes automatically and refer to the stiffness and bandwidth 
setting of P2-31. 
1.  Set the system to manual mode 0 from auto 1 or semi-auto 2, the 
system will save the estimated inertia value to P1-37 automatically 
and set the corresponding parameters. 
2.  Set the system to auto mode 1 or semi-auto mode 2 from manual 
mode 0, please set P1-37 to the appropriate value. 
3.  Set the system to manual mode 0 from auto mode 1, P2-00, P2-04, 
P2-06, P2-25, P2-26 and P2-49 will be modified to the 
corresponding parameters of auto mode. 
4.  Set the system to manual mode 0 from semi-auto mode 2, P2-00, 
P2-04, P2-06, P2-25, P2-26 and P2-49 will be modified to the 
corresponding parameters of semi-auto mode.
