CHAPTER 4 - KEYPAD (HMI) OPERATION
Inverteris Ready to be started.
Line voltage is too low for inverter
operation (undervoltage condition).
Inver
ter is in a fault condition. Fault code
is flashing on the display. In the example
there is the fault code E02 (refer to
chapter 7).
Inverter is applying a DC current on the
motor (DC braking)
according to the
values programmed at P300, P301 and
P302 (refer to chapter 6).
Inverter is running self-tuning routine to
identify motor parameters automatically.
This operation is controlled by P408
(refer to chapter 6).

from the HMI into the inverter.
Inverter in the Sleep rdy mode.
NOTE!
The display also flashes in the following conditions, besides
the fault conditions:
Trying to change a parameter value when it is not allowed.
Inverter in overload condition (refer to chapter 7).

the keys:
When pressed, it increases the speed (frequency)reference.
Whenpressed, it decreases the speed (frequency) reference.
Reference Backup:
The last frequency reference set by the keys and
is
stored when inverter is stopped or theAC power is removed,
provided P120 = 1 (reference backup active is the
factory
default).Tochange thefrequencyreference before starting the
inverter, thevalue ofthe parameter P121 mustbe changed.
