The menu tree illustrated on this page outlines the important menu options that provide useful information for monitoring and diagnostic purposes when using the machine.

As can be seen on the menu tree to the right, when the machine is turned on, the variable speed drives or frequency converters are set to display the Output Fre- quency to the motor (a zero value will register when the machine is in stand-by mode).

The Output Frequency page also falls under the Monitor Menu.

It can be seen from the left hand column, the two primary menus important to the operator are the Monitor Menu and Fault History menu.

Navigation through the menu tree is achieved by us- ing the up, down, left and right keys on the keypad (see previous page).
