4 KEYPAD (HMI) AND BASIC PROGRAMMING

4.1 USE OF THE KEYPAD TO OPERATE THE INVERTER

Through the HMI, it is possible to command the inverter, visualize and adjust all of its parameters. The Keypad
features the following functions:
Selects (switches) between the
parameter number and its value
(position/content).
Decreases (decrements) the
frequency, parameter number or
parameter value.

4.2 INDICATIONS ON THE HMI DISPLAY

Direction of rotation

4.3 OPERATING MODES OF THE HMI

When energizing the inverter, the initial state of the keypad remains in the initialization mode as long as there is no
fault, alarm, undervoltage or any key is pressed.
The setting mode is composed of two levels: Level 1 allows the navigation through the parameters. And level 2
allows the edition of the parameter selected at level 1. At the end of this level, the modified value is saved when
the key is pressed.
Figure 4.3 on page 26 illustrates the basic browsing of the operating modes of the HMI.
