• 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.

(continued, next page...)

• 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.

Parameter tables for user-settable functions follow these conven­tions:

• 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 (Europe) / – FU (U.S.) / –FR (Japan).

• Some parameters cannot be edited during Run Mode, and certain
Software Lock settings (B_31) can prohibit all edits. If in doubt,
place the inverter in Stop Mode or consult the inverter manual for
details.
