Motor Overload Protection
Hitachi L300P inverters provide solid state motor overload protection,
which depends on the proper setting of the following parameters:
• B012 “electronic overload protection”
• B212 “electronic overload protection, 2nd motor”
Set the rated current [Amperes] of the motor(s) with the above parame-
ters. The setting range is 0.2 * rated current to 1.2 * rated current.
Warning: When two or more motors are connected to the
inverter, they cannot be protected by the electronic overload pro-
tection. Install an external thermal relay on each motor.

Inverter Keypad Operation
•Run/Stop LED – ON when the inverter output is ON and the motor is
developing torque, and OFF when the inverter output is OFF (Stop
Mode).
•Program/Monitor LED – This LED is ON when the inverter is ready
for parameter editing (Program Mode). It is normally OFF when the
parameter display is monitoring data (Monitor Mode). However, the
PRG LED will be ON whenever you are monitoring the value of
parameter D001. (When the keypad is enabled as the frequency source
via A001=02, you can edit the inverter frequency directly from D001
monitor display by using the Up/Down keys.)
•Run Key Enable LED – ON when the inverter is ready to respond to
the Run key, OFF when the Run key is disabled.
•Run Key – Press this key to run the motor (the Run Enable LED must
be ON first). Parameter F004, Keypad Run Key Routing, determines
whether the Run key generates a Run FWD or Run REV command.

•Stop/Reset Key – Press this key to stop the motor when it is running
(uses the programmed deceleration rate). This key will also reset an
alarm which has tripped.
•Potentiometer – Allows an operator to directly set the motor speed
when the potentiometer is enabled for output frequency control.
•Potentiometer Enable LED – ON when the potentiometer is enabled
for value entry.
•Parameter Display – A 4-digit, 7-segment display for parameters and
function codes.
•Display Units: Hertz/Volts/Amperes/kW/% – These LEDs indicate
the units associated with the parameter display. When the display is
monitoring a parameter, the appropriate LED is ON. In the case of kW
units, both Volts and Amperes LEDs will be ON. An easy way to
remember this is that kW = (V x A)/1000.
•Power LED – ON when the power input to the inverter is ON.
•Alarm LED – ON when an alarm condition has tripped the inverter.
Clearing the alarm will turn this LED OFF again. See page 13 for
details on clearing alarms.
•Function Key – This key is used to navigate through the lists of
parameters and functions for setting and monitoring parameter values.
•Up/Down Keys – Use these keys alternately to move up or down the
lists of parameter and functions shown in the display, and to increment/
decrement values.
•Store Key – When the unit is in Program Mode and the operator has
edited a parameter value, press the Store key to write the new value to
the EEPROM. This parameter is then displayed at powerup by default.
If you want to change the powerup default, navigate to a new parameter
value and press the Store key.

Powerup Test
The Powerup Test procedure uses minimal parameter settings to run the
motor. The procedure describes two alternative methods for commanding
the inverter: via the inverter keypad, or via the logic terminals.
• Check power input and motor output wiring (see page 8 diagram).
• If using logic terminals for testing, verify correct wiring on [FW],
[CM1], [H], [O], and [L] per the diagram on page 8.
• Reverse [RV] input wiring (defaults to terminal [8]) is optional.

Error Codes
The L300P series inverters will trip on over-current, over-voltage, and
under-voltage to protect the inverter. The motor output turns OFF, allow-
ing the motor to free-run to a stop. Press the Stop/Reset key to reset the
inverter and clear the error.
Basic Error Codes
Error
Code Name Probable Cause(s)
E01 Over current event while at
constant speed
• Inverter output was short-circuited
• Motor shaft is locked
• Load is too heavy
• A dual-voltage motor is wired
incorrectly
Note: The L300P will over current trip
at nominally 200% of rated current
E02 Over current event during
deceleration
E03 Over current event during
acceleration
E04 Over current event for other
conditions
• DC braking power(A054) set too high
• Current transformer / noise error
E05 Overload protection • Motor overload is detected by the
electronic thermal function
E06 Braking resistor overload • Regenerative braking resistor exceeds
the usage time or usage ratio
E07 Over voltage
protection
• DC bus voltage exceeds a threshold,
due to regenerative energy from motor
E08 EEPROM error • Built-in EEPROM memory experi-
enced noise, high temperature, etc.
E09 Under-voltage error • DC bus voltage decreased enough to
cause a control circuit fault
E10 CT error
(current transformer)
• High electrical noise near inverter
• A fault occurred in the built-in CT
E11 CPU error • Built-in CPU had internal error
E12 External trip • [EXT] input signal detected
E13 USP (Unattended Start
Protection)
• When (USP) was enabled, an error
occurred when power was applied while
a Run signal was present
E14 Ground fault • A ground fault was detected between
the inverter output and the motor. This
feature protects the inverter, and does
not protect humans.
E15 Input over-voltage • Input voltage was higher than the
specified value, 60 sec. after powerup
E16 Instantaneous power failure • Input power removal > 15ms or
> B002... inverter restarts on Run cmd

14
Error Status Codes and Error Trip Conditions
The digit to the right of the decimal point in the error code (such as E01.4)
indicates inverter status at the moment the error occurred. Use the Up and
Down arrow keys to scroll through the trip condition parameters.
E21 Inverter thermal trip • Inverter internal temperature is above
the threshold
E23 Gate array error • An internal inverter error has occurred
(CPU / gate array IC)
E24 Phase failure detection • One of three lines of the 3-phase
power is missing
E30 IGBT error • Instantaneous over-current on any
IGBT (output transistor) device
E35 Thermistor • Thermistor input, [TH] and [CM1], is
over the temp. threshold
–––– Under-voltage (brownout)
with output shutoff
• Low input voltage caused the inverter
to turn OFF the motor output and try to
restart. If unsuccessful, a trip occurs.
Automatic restart and phase
loss
• Inverter is restarting, due to an over-
current, over-voltage, under-voltage, or
a phase loss event.
E6X Expansion card #1 error • An error has occurred in an
expansion card or at its connecting
terminals. Please refer to the manual for
the expansion card for additional details.

Parameter tables for user-settable functions follow these conventions:
• Some parameters have 2nd and 3rd motor equivalents, indicated by the
x2xx and x3xx parameter codes in the left-most column.
• Some parameters specify an option code. Where applicable, the
options codes will be in a bulleted list in the Name/Description
