Keys, Modes, and Parameters

The purpose of the keypad is to provide a way to change modes and parameters. The term function applies to both monitoring modes and parameters. These are all accessible through function codes that are primary 4-character codes. The various functions are separated into related groups identifiable by the left-most character, as the table shows.

You can see from the following page how to monitor and/or program the parameters.

Keypad Navigation Map

The WJ200 Series inverter drives have many programmable functions and parameters. Chapter 3 will cover these in detail, but you need to access just a few items to perform the powerup test. The menu structure makes use of function codes and parameter codes to allow programming and monitoring with only a 4-digit display and keys and LEDs. So, it is important to become familiar with the basic navigation map of parameters and functions in the diagram below. You may later use this map as a reference.
