1 The base frequency (the maximum frequency) calculates to the following by the rated revolution (the
*
maximum revolution) of the motor and motor pole.
Base frequency
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
*
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.)
