"H" Group: Motor Constants Functions Section 3-8
Note 5 If the inverter trips during the auto-tuning, the auto-tuning is interrupted. After
removing the cause of trip, retry auto-tuning from the beginning.
Note 6 If inverter is stopped during auto-tuning by stop command (by STOP key or
deactivate RUN input), measured constants could remain. Be sure to execute
auto-tuning again.
Note 7 If auto-tuning is attempted in free V/f setting, auto-tuning will fail with error dis-
play.
3-8-4 Permanent Magnet motor
When PM mode is selected on b171=03 and after initialization b180=01 new
motor parameters appears on the "H" group replacing most of the standard IM
parameters that dissapears. Next table shows this new parameters that
should be used to adjust the motor characteristics
