L100 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: 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.

Note that a braking unit is not included in the inverter. If a large regenerative

torque is required, the optional regenerative braking unit should be used.

Note 6: 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 representa-

tive.

Note 7: If operating the inverter in an ambient temperature of 40–50° 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 8: The storage temperature refers to the short-term temperature during transport.

Note 9: Conforms to the test method specified in JIS C0911 (1984). For the model

types excluded in the standard specifications, contact your Hitachi sales repre-

sentative.

Note 10: The input voltage of xxLFU is 230V.

Item General Specifications

L100 Inverter

Derating Curves

The maximum available inverter current output is limited by the carrier frequency and

ambient temperature. The carrier frequency is the inverter’s internal power switching

frequency, settable from 0.5 kHz to 16 kHz. Choosing a higher carrier frequency tends to

decrease audible noise, but it also increases the internal heating of the inverter, thus

decreasing (derating) the maximum current output capability. Ambient temperature is

the temperature just outside the inverter housing—such as inside the control cabinet

where the inverter is mounted. A higher ambient temperature decreases (derates) the

inverter’s maximum current output capacity.

Use the following derating curves to help determine the optimal carrier frequency setting

for your inverter, and to find the output current derating. Be sure to use the proper curve

for your particular L100 inverter model number.
