KEYPAD (HMI) AND BASIC PROGRAMMING
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.
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 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.
