To get the system inertia from Pr.11-01, user needs to set Pr.11-00 to 2 and execute
continuous forward/reverse running.

After estimating inertia and set Pr.11-00 to 1 (auto tuning), user can adjust parameters Pr.11-
02, 11-03 and 11-11 separately by speed response. The larger number you set, the faster
response you will get. Pr.10-08 is the switch frequency for low-speed/high-speed bandwidth.
