Motor Overload Protection
Hitachi L2002inverters 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 – ON when the inverter is ready for parame-
ter editing (Program Mode). It is OFF when the parameter display is
monitoring data (Monitor Mode).
•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/Amperes – One of these LEDs will be ON to
indicate the units associated with the parameter display.
•Power LED – ON when the power input to the inverter is ON.
•Alarm LED – ON when the inverter in Trip Mode.
•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.

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 [PCS],
[FW], [H], [O], and [L] (bottom row) per the diagram on page 8.
• Reverse [RV] input wiring (defaults to terminal [2]) is optional.

Error Codes
The L2002series 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 L2002will 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
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
E11
E22
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 specified
value, after 60 sec. in Stop Mode
E21 Inverter thermal trip • Inverter internal temperature is above
the threshold
E30 Driver error • Inverter internal error, electrical noise
at CPU-to-drive circuit interface.

14
Error Trip Conditions
Use function code D081 to access the error trip conditions for the current
error as shown in the table below. Use the Up and Down arrow keys to
scroll through the trip condition parameters.
E35 Thermistor • Thermistor input, [THM] and [L], is
over the temp. threshold
E60 Communications error • The inverter’s watchdog timer for the
communications network has timed out.
--- 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.

Parameter tables for user-settable functions follow these conventions:
• Some parameters have 2nd motor equivalents, indicated by the x2xx
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
column.
• The default values apply to all models unless otherwise noted for each
parameter... –FE(F) (Europe) / – FU (U.S.)
• Some parameters cannot be edited during Run Mode, and certain
Software Lock settings (B031) can prohibit all edits. If in doubt, place
the inverter in Stop Mode or consult the inverter manual for details.
