4 HMI AND BASIC PROGRAMMING
4.1 USE OF THE HMI TO OPERATE THE INVERTER
Using the HMI, it is possible to command the inverter, view and adjust all of its parameters. The HMI presents the
following functions:
Selects (switches) between
the parameter number and its
value (position/content).
Decreases (decrements)
the frequency, parameter
number or parameter value. Increases (increments) the
frequency, parameter number
or parameter value.
Enables/Disables the inverter via
acceleration/deceleration ramp
(start/stop, according to P229).
Resets the inverter after a fault.

4.3 OPERATING MODES OF THE HMI
When inverter is powered-up, the initial state of the HMI remains in the start-up mode as long as no faults, alarms,
undervoltages occur or no keys are pressed.
The setting mode is composed of two levels: Level 1 allows browsing the parameters. Level 2 allows the modification
of the parameter selected in level 1. At the end of this level, the modified value is saved when the key is pressed.
The Figure 4.3 on page 4-2 illustrates the basic browsing of the operating modes of the HMI.
