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.
*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.
*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.
*4
The protection method conforms to JIS C 0920(IEC60529).
*5
To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the maximum allowable rotation speed.
*6
The output frequency may exceed the maximum frequency setting (A004 or A204) for automatic stabilization control.
*7
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.
