Basic Wiring Diagram

The following wiring diagram shows the power and motor connec-

tions for basic operation. The optional signal input wiring supports

external Fwd and Rev Run command, and a speed potentiometer.

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

parameter 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 F_04, 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 parame-

ters 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.

•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 4 diagram).

• If using logic terminals for testing, verify correct wiring on [P24],

[FW], [H], [O], and [L] (bottom row) per the diagram on page 4.

• Reverse [RV] input wiring (defaults to terminal [2]) is optional.

Error Codes

The L100 series inverters will trip on over-current, over-voltage, and

under-voltage to protect the inverter. The motor output turns OFF,

allowing 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 L100 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(A_54) 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 the

specified value, 60 sec. after powerup

E21 Inverter thermal trip • Inverter internal temperature is

above the threshold
