Note 1: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). When using other motors, care
must be taken to prevent the rated motor current (50/60 Hz) from exceeding the rated output current of
the inverter.
Note 2: The output voltage decreases as the main supply voltage decreases (except when using the AVR
function). In any case, the output voltage cannot exceed the input power supply voltage.
Note 3: The braking torque via capacitive feedback is the average deceleration torque at the shortest
deceleration (stopping from 50/60 Hz as indicated). It is not continuous regenerative braking torque.
The average decel torque varies with motor loss. This value decreases when operating beyond 50 Hz.
Note 4: The protection method conforms to JIS C 0920(IEC60529).
Note 5: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the
maximum allowable rotation speed.
Note 6: The output frequency may exceed the maximum frequency setting (A004 or
A204) for automatic stabilization control.
Note 7: At the rated voltage when using a Hitachi standard 3-phase, 4pole motor.
Note 8: DC 4 to 20 mA Input, need parameter setting by Keypad etc.
Analog input voltage or current can be switched by switch as individually and not
use them in the same time.
