LC - Control Setting Parameters
If the inertia learn procedure has taken place, then the Speed Gain Optimization
provides a quick adjustment of the speed control response on a scale between
0 = ‘Soft’ and 25= ‘Hard’. From the learned inertia value, the drive determines
a ratio between the proportional and integral gain and adjustment of the
optimization will scale each accordingly.
The system inertia must be learned for the Speed Gain Optimization to be
implemented. Optimization will lower the KI gain. For reference a value
of 10 in LC02 normalizes the Kp value to 3000. So if LC02 = 10, the Kp
gain goes to 3,000 and the KI gain drops to what is calculated. This is the
best starting point. Refer to section 5.12.1 for learning the system inertia.
In most cases, the default settings for the Proportional and Integral
speed control gains should provide a very good starting point for proper
operation and ride quality. If adjustment is needed, it would be suggested
to perform the Inertia Learn (Section 5.12.1) procedure, which can improve
performance with little or no further adjustment to the Proportional and
Integral speed control gains.
