EASY-REMOVABLE COOLING FAN

AND DC BUS CAPACITOR

Cooling fan(s) and DC bus capaci-tors can be easily changed in the field. A fan ON/OFF function can be activated to provide longer cooling fan life.

The L300P’s compact size helps economize panel space. Installation area is reduced by approximately 30% from that of our previous series.

(Comparison of 11kW (15HP))

REMOVABLE CONTROL CIRCUIT TERMINALS

Eliminates control rewiring when field replacing the L300P.

Control Circuit Terminals

EASE OF OPERATION WITH DIGITAL OPERATOR(OPE-SR)

Output frequency can be controlled by the integral potentiometer provided as standard on the OPE-SR.

The OPE-SR can be removed for remote control, and has an easy-to-see 4-digit display and LEDs to indicate the unit being monitored (i.e. frequency, amps, power, etc.).

A multilingual operator (English, French, German, Italian, Spanish, and Portuguese) with copy function (SRW- 0EX) and a digital operator without potentiometer (OPE- S) are also available as options.

USER SELECTION OF COMMAND FUNCTIONS (“Quick Menu”)

You can select frequently used commands and store them for fast reference.

BUILT-IN RS485

RS485 is provided as standard for ASCII serial communication.

PROGRAMMING SOFTWARE

Optional PC drive configuration software which runs on Windows® Operating System.
