Basic Wiring Diagram The following wiring diagram shows the power and motor connections for basic operation. The optional signal input wiring supports external Fwd and Rev Run command, and a speed potentiometer.

• 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.

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.
Error Code E35 --- Name Probable Cause(s) Thermistor • Thermistor input, [THM] and [L], 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. Error Trip Conditions Use function code D_08 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.

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.
