2 Please pay attention that settings of H104 to H110, A003 and A004 will be changed automatically, when PM
motor capacity (H103) is changed.
*
3 PM induction voltage constant Ke is the peak voltage of one phase of per electrical angle speed (rad/s).
*
4 PM moment of inertia J is value (kgm
2
) that added the moment of inertia of the load machine that converting
the moment of inertia into the motor shaft data to the moment of inertia of the motor.
*
5 Even if the auto-tuning has ended normally, you cannot operate the inverter with the tuning data left. If you
intend to operate the inverter with the tuning data left, be sure to switch the setting of motor constant
selection (H102) to "01".
*
6 If the auto-tuning has ended abnormally, you confirm the motor cable and the parameter setting, and retry
it.
*
7 If you cancel the auto-tuning midway with a stop command (by pressing the STOP/RESET key or turning off
the operation command), the constants set for auto-tuning may remain in the inverter. Before retrying the
auto-tuning, initialize the inverter, and then readjust the settings for the auto-tuning. (Perform the same
procedure also when you proceed to the normal inverter operation.)
