Err N° Failure Failure Name
351 Err EP* Encoder phase
error
352 Err E.11* Opposite rotation
deceleration
353 Err E.13 Internal circuit error
* : This option or function is not used. If you have this error anyway do the following :
1) Reload the inverter parameters.
2) If the fault is persistent, replace the inverter.
DIAGNOSE FAILURE 300-301-302: OC-ERRORS (OVERCURRENT)
1. Check if there is no short circuit on the
output of the inverter. (loose wire of motor
cable, motor windings, screws or other loose
parts inside the motor terminal box,...)
2. Disconnect the motor cable from the inverter and
try again.
DIAGNOSE FAILURE 303-304-305 : OV-ERRORS (OVERVOLTAGE)
If the DC-voltage on the capacitors is too high, the inverter will generate OV error.
1. Check if there was a high unbalance during
extraction, which can be caused by putting
only half loads in the machine.
2. Check if the supply voltage is not too high.
3. Check if the fault is persistent
DIAGNOSE FAILURE 306: THT-ERROR (INVERTER OVERLOAD)
If the output current of the inverter is abnormal high for some time, the inverter will go into THT-alarm
state.
1. Check if the power supply is sufficient high
and stable during extraction with load.
2. Check if the drum rotates normally by hand.
(no abnormal high friction)
3. Check if the motor windings are OK.
DIAGNOSE FAILURE 307: THM-ERROR (MOTOR OVERLOAD)
If the motor current is higher than allowed for a longer time, the inverter will activate the electronic
overcurrent protection to prevent the motor from overheating and the inverter will go into THM-alarm state.
1. Check if the drum rotates normally by hand.
2. Check if the motor windings are OK.
3. Check if the fault is persistent.
DIAGNOSE FAILURE 309: OLT-ERROR (STALL PREVENTION)
The output frequency has dropped to minimum because of current limitation.
1. Check if the power supply is sufficient high and
stable during extraction with load.
2. Check if the drum rotates normally by hand.
(no abnormal high friction)
3. Check if the motor windings are OK.

Explanation
Rotation command different than the motor rotation
direction
Rotation direction of the speed command different than the
estimated speed causing overload
Problem with an internal circuit, replace the inverter
Repair the short circuit.
If you still have the error with motor cable
disconnected, replace the inverter.
Put always a full load in the machine drum.
Reduce the supply voltage.
If the fault is persistent, contact the manufacturer
Repair the power supply.
Repair / clean what is necessary.
Replace the motor.
Repair / clean what is necessary.
Replace the motor.
If the fault is persistent, contact the manufacturer.
Repair the power supply.
Repair / clean what is necessary.
Replace the motor.
