4.2.2 Inverter Status
CHAPTER 4 - KEYPAD (HMI) OPERATION
Parameter P121 stores the speed (frequency) reference set by
the keys:
When pressed, it increases the speed (frequency) reference.
When pressed, it decreases the speed (frequency) reference.
Reference Backup:
The last frequency reference set by the keys
stored when inverter is stopped or the AC power is removed,
provided P120 = 1 (reference backup active is the factory
default). To change the frequency reference before starting the
inverter, the value of the parameter P121 must be changed.
Inverter is Ready to be started.
Line voltage is too low for inverter
operation (undervoltage condition).
Inverter is in a fault condition. Fault code
is flashing on the display. In the example
there is the fault code E02 (refer to
chapter 6).
Inverter is applying a DC current on the
motor (DC braking) according to the
values programmed at P300, P301 and
P302.
Inverter is running self-tuning routine to
identify motor parameters automatically.
This operation is controlled by P408.
COPY function (available only at the HMI–
CFW08-RS), it copies the inverter
programming into the HMI.
COPY function (available only at the HMI–
CFW08-RS), it copies the programming
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 6).
