Sensorless Vector Control

The torque calculation software (sensorless vector control) developed by Hitachi ensures accurate torque control throughout the entire frequency range, even with general purpose motors.

• High starting torque of 200%or more (3.7kW~ : 180% or more)

• 100% continuous operating torque within a 1:10 speed range (6 to 60 Hz/5 to 50 Hz) without motor de-rating. (3.7kW~: 1:3

(

20~60Hz))

Location

*1: The protection method conforms to JEM1030. *2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). To use

other motors, care must be taken to prevent the rated motor current from exceeding the rated output current of the inverter.

*3: The output voltage decreases as the main power supply voltage decreases. (Except

for use of the AVR function)

*4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer about the

maximum allowable rotation speed. *5: SLV selected, set carrier frequency more than 2.1kHz. *6: At the rated voltage when using a Hitachi standard 3-phase, 4-pole moter.(When

selecting high starting torque flux vector contlrol) *7: The braking torque at capacitive feedback is the average deceleration torque at the

shortest deceleration (stoppage from 50 Hz) of the motor itself. It is not the continuous regenerative braking torque. And the average deceleration torque varies with motor loss. This value decreases when operating beyond 50/60 Hz. If a large regeneration torque is required, the optional braking resistor should be used.

*8: The frequency command is the maximum frequency at 9.8 V for input voltage 0 ~ 10

VDC, or at 19.6 mA for input current 4 ~ 20 mA. If this characteristic is not convenient, contact your Hitachi sales representative.

*9: To use the inverter at 40

C or higher, reduce carrier frequency 2.1kHz and derate

output current 80%, and remove the top cover. *10: The storage temperature refers to the short-term temperature during transport. *11: Conforms to the test method specified in JIS C0040 (1999). For the model types

excluded in the standard specifications, contact your Hitachi sales representative.
