Possible cause
Defective option board or slot.
Identification run has failed.
The actual status of the mechanical
brake differs from the control signal
for longer than what is defined.
The drive stops because there is no
sufficient power from the solar pan-
els.
The drive cannot start because the
DC voltage is below the threshold in
P1.18.
The drive is waiting for the program-
med time before starting again.
The water level in the well is below
the minimum level.
The minimum water level is insuffi-
cient.
The water level in the tank is above
the maximum level.
The data connection between the PC
and the frequency converter is bro-
ken.
The thermistor input has detected an
increase of the motor temperature.
Maintenance counter has reached

Remedy
Check the board and the slot.
Check that the motor is connec-
ted to the drive.
Ensure that there is no load on
the motor shaft.
Ensure that the start command is
not removed before the comple-
tion of the identification run.
Check the status and connec-
tions of the mechanical brake.
Wait for more solar irradiation or
add more solar panel strings.
Wait until the programmed time
is elapsed.
Dry run is detected. Check the
settings and the status of the wa-
ter level.
Check the settings and the sta-
tus of the water level.
Check the settings and the sta-
tus of the water level.
Check the motor cooling and
load.
Check the thermistor connection.
(If the thermistor input is not in
use, it must be short circuited)
