Chapter 6 Control Modes of Operation
ASDA-B2
6-22
Revision May, 2018
Many kinds of gain in speed control unit are adjustable. Two ways, manual and auto, are
provided for selection.
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, and P2-06 will be modified to the corresponding
