Description
Current loop Kp
Increase Kp to make current rise fast. Proportional
Gain determines the response of the drive to setting
command. Low Proportional Gain provides a stable
system (doesn’t oscillate), has low stiffness, and the
current error, causing poor performances in tracking
current setting command in each step. Too large
proportional gain values will cause oscillations and
unstable system.
Current loop Ki
Adjust Ki to reduce the steady error. Integral Gain
helps the drive to overcome static current errors. A
low or zero value for Integral Gain may have current
errors at rest. Increasing the integral gain can reduce
the error. If the Integral Gain is too large, the system
may “hunt” (oscillate) around the desired position.
Damping
coefficient
This parameter is used to change the damping
coefficient in case of the desired operating state is
under resonance frequency.
Position loop Kp
The PI parameters of the position loop. The default
values are suitable for most of the application, you
don’t need to change them.
