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 JEM 1030.
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
Application
This series is well-suited for applications where basic speed control is required, such as:
- Fans
