• 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.

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.
Error Code Name Probable Cause(s) E21 Inverter thermal trip • Inverter internal temperature is above the threshold E23 Gate array error • An internal inverter error has occurred (CPU / gate array IC) E24 Phase failure detection • One of three lines of the 3-phase power is missing E30 IGBT error • Instantaneous over-current on any IGBT (output transistor) device E35 Thermistor • Thermistor input, [TH] and [CM1], is over the temp.

Programming Error Codes The L300IP inverter operator keypad displays a special code (begins with the character) to indicate a programming error. Programming errors exist when one parameter conflicts with the meaningful range permitted by related parameter(s). Note that particular real-time frequency (speed) input levels can cause a conflict in some situations. After a conflict exists, the error code will appear on the display, or you can view it later with D090 in Monitor Mode.
