L300P Inverter i Safety Messages For the best results with the L300P Series inverter, carefully read this manual and all of the warning labels attached to the inverter before installing and operating it, and follow the instructions exactly. Keep this manual handy for quick reference. Definitions and Symbols A safety instruction (message) includes a hazard alert symbol and a signal word, WARNING or CAUTION. Each signal word has the following meaning: This symbol indicates HIGH VOLTAGE. [. . . ] P050=01: The output frequency is forced to 0 Hz, recovering 500ms after the analog input exceeds the Start Frequency value. P050=02: The output frequency is forced to the Maximum Frequency value (A004), recovering 500ms after the analog input exceeds the Start Frequency value. P050=03: The output frequency is forced to the Multi-Speed 1 setting (A020/A220), recovering 500ms after the analog input exceeds the Start Frequency value. The timing diagram below illustrates the four available output frequency responses for a disconnect event, using the different P050 settings. For the purpose of this example, the analog input "disconnect" value is less than the start frequency but slightly greater than zero.

This feature provides quick access for the most-used functions needed for your application. Each U Group function can serve as a pointer to any of the other parameters. You do not have to use the Store key to retain each association; just scroll to the desired standard parameter for each U Group function and leave it. The setting can point to a monitor-only parameter (such as D001), or point to editable parameters (such as A001). In the case of pointing to an editable functions, you use the Up/Down keys to change the value and the Store key to accept the change into memory--the same procedure as a normal parameter edit.

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. Also, the PGM LED on the display will flash ON/OFF when programming. These indications are automatically cleared when the parameter is corrected to the allowed range.

[. . . ] Very often, the terminal boxes, and particularly the threads for the metal PG screw connections, are painted. Make sure there is always a good metallic connection between the shielding of the motor cable, the metal PG screw connection, the terminal box, and the motor housing. If necessary, carefully remove paint between conducting surfaces. Take measures to minimize interference that is frequently coupled in through installation cables. [. . . ]
