machine alarms documented on
Possible cause
Remedy
1) OCF overcurrent
- ramp too short
- inertia or load too high
- mechanical locking
- check the state of the
mechanism.
2) SCF motor short circuit
- insulation fault or shortcircuit at the drive output
check
the
cables
connecting the drive to the
motor , and the motor
insulation.
3) InF internal fault
- internal fault
- check the environment
(electromagnetic
compatibility).
- send the drive to be
checked/repaired.
4) CFF configuration fault
- The current configuration is
inconsistent
- some parameters in the
inverter have been
- return to factory settings.
5) SOF overspeed
- instability or
- driving load too high
- some parameters in the
inverter have been
modified
- return to factory settings.
6) CrF internal fault
- load relay control fault or
damaged load resistor
- replace the drive.
7) OHF drive overload
- drive temperature too high
- check the motor load and
the enviroment.Wait for the
drive to cool down before
restarting.
8) OLF motor overload
- triggered by motor current
too high
- check the motor load. Wait
for the drive to cool down
before restarting.
9) OSF overvoltage
- line voltage too high
- disturbed line supply
- check the line voltage. The
overvoltage thresold is 415
V on the DC bus.
10) ObF
overvoltage during
deceleration
- braking too sudden or
driving load.
- increase the deceleration
time.
11) PHF line phase failure
- drive incorrectly supplied
or a fuse blown
- failure of one phase
- unbalanced load
- check the power
connection and the fuses.
- reset.
12) USF undervoltage
- line supply too low
- transient voltage dip
- damaged load resistor
- check the voltage and
the voltage parameter.
The undervoltage
threshold is 230 V on the
DC bus.
- replace the drive.
13) ULF
Current level above the
overload threshold LOC.
- Check the value of the
parameters LOC and tOL
in the menu FUn.
- Check the mechanics
(wear, mechanical stops,
lubrication, obstacles, etc.).
14) ULC
Current level below the
under-load threshold LUL.
- Check the value of the
parameters LUL and tUL
in the menus FUn.

Lack of detergent
The lack of detergent warning is generated when a wash cycle is in progress and the conductivity
sensor installed in the tank detects that for 6 minutes (parameter dAd Detergent alarm delay) the
concentration of detergent in the tank is below the set point value, and more precisely when
Compensated conductivity < Detergent set point + Detergent set point offset. If the concentration of
detergent in the tank is below the set point, the low level warning (not visible to the user) is
immediately generated, but if after 6 minutes the concentration continues to remain low, the
message visible to the user is generated.
