Hitachi Vector Control with the SJ300 Inverter - Page 13

Ø Note that these plots were made under steady state conditions, i.e. not transient data.
Transient response cannot be determined from these plots.
Ø There is no set procedure or specific order for these tuning steps, because optimal tuning depends on
the conditions and situation of the system. Refer to Table 2 in previous section for suggestions for tuning.
