SJ100 Inverter Specifications
Footnotes for the preceding table and the tables that follow:
Note 1: The protection method conforms to JEM 1030.
Note 2: 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 3: 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 4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for
the maximum allowable rotation speed.
Note 5: When SLV is selected, please set the carrier frequency higher than 2.1 kHz.
Note 6: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor
(when selecting sensorless vector control—SLV).
Note 7: 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 deceleration torque
varies with motor loss. This value decreases when operating beyond 50 Hz. If
a large regenerative torque is required, the optional regenerative braking
resistor should be used.
Note 8: The frequency command is the maximum frequency at 9.8V for input voltage
0 to 10 VDC, or at 19.6 mA for input current 4 to 20 mA. If this characteristic
is not satisfactory for your application, contact your Hitachi sales representative.
Note 9: If operating the inverter at 40 to 50° C, reduce the carrier frequency to 2.1
kHz, derate the output current by 80%, and remove the top housing cover.
Note that removing the top cover will nullify the NEMA rating for the inverter
housing.
Note 10: The storage temperature refers to the short-term temperature during transport.
Note 11: Conforms to the test method specified in JIS C0911 (1984). For the model
types excluded in the standard specifications, contact your Hitachi sales representative.
Note 12: The input voltage of xxLFU is 230V.
