The following wiring diagram shows the power and motor connections
for basic operation. The optional signal input wiring supports external

• 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.

• 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 9 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 4 diagram).

• If using logic terminals for testing, verify correct wiring on [FW],
[CM1], [H], [O], and [L] per the diagram on page 4.

• 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, allow­ing the motor to free-run to a stop. Press the Stop/Reset key to reset the
inverter and clear the error.
