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.
