Description Resaon
Remedy
O.C.
Over-current – hardware
detected
OC1
Over-current – software
detected
Too short ramps, short circuit on output
motor defect, system blocked, wrong
motor parameter setting
Increase Accel/Decel ramp time
Check cabling / motor
Check mechanical system
Reduce BOOST
Check motor parameter setting
O.L1
Inverter overload
Overload
O.L2
Motor overload
Overload
Reduce load
Check for right dimensioning
O.E.
DC-link over-voltage
Input power over-voltage
Too high inertia
Deceleration ramp too short
Improper PID controller parameter
Check for correct supply voltage
Inverter rated voltage correct??
Use larger brake resistors
Increase deceleration time
P.F1.
Phase-loss Input
One input-phase missing
Check power supply
PF0
Phase-unbalance output
Motor-phase / cabling interrupted
Check cabling / check motor
L.U.
Undervoltage
Voltage on DC_Link too low
Check power supply
O.H.
Inverter overheat
Environment temperature too high
Poor cabinet heat-exchange
Inverter / heatsink polluted
PWM frequency too high
Motor cable too long
Check for environment / working
conditions
Insert all parameters correctly
Check for correct inverter mounting
AErr
Analogue signal
interruption
The analogue signal value is below the
lower limit, programmed in
F4xx
parameters
Inspect control cabling
Insert correct parameters for
analogue signal lower limit
Measure reference signal source
nP
Pump control: Pressure
beyond limits
Pressure beyond limits
Inverter in SLEEP mode
Insert correct pump controller
parameters – open water flow
CE
MODBUS time-out
MODBUS signal missing
Check MODBUS cabling / source –
MODBUS parameter setting
FL
Time-out "Catch on the
fly" function
Syncronizing time exceeded the value in
F619
Optimize "Chatch" parameters
ERR1
Wrong password
Parameter change not
successful
No or wrong password input
Parameter change not allowed
Insert correct password
STOP inverter to allow parameter
change
(for certain parameters only)
ERR2
Autotuning error
Motor can not free rotate during dynamic
testing cycle
Separate motor from drive system
ERR3
Overcurrent in STOP
condition
Hardware failure
Visual inspection of internal cabling
Contact EURA service-center
ERR4
Current sensor error
No current signal on control board
Visual check of internal cabling,
contact EURA service-center
ERR5
PID ERROR
PID controller error, due to improper PID
parameter
Set PID parameter correctly
ERR6
Watchdog Timeout
Timeout caused by missing watchdog
signal
Check signal on dig. input - assign
digital input to watchdog function
