CHAPTER 4 - KEYPAD (HMI) OPERATION
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–
CFW 08-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).
4.2.2 Inverter Status
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
and
is
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.
