Using Keypad Devices

Inverter Front
The SJ300 Series inverter front keypad contains all the elements for both monitoring and
Panel Keypad programming parameters. The keypad layout (OPE–SRE) is shown below. All other program-
ming devices for the inverter have a similar key arrangement and function.

A001=02, you can edit the inverter frequency directly from D001 monitor display by using
the Up/Down keys.)

way to remember this is that kW = (V x A)/1000.
