PROBLEMS - ERROR MESSAGES
GB
Error messages (main errors)
E01 Overcurrent at constant speed
(fan at cruising speed)
E02 Overcurrent during deceleration
(fan about to stop)
E03 Overcurrent during acceleration
(fan is starting up)
E04 Overcurrent when stopped
E05 Motor overload
E09 Network undervoltage
E14 Earth leakage current
E15 Overvoltage on the power supply voltage
E08 EEPROM reading error
E11
E22
E21 Thermal protection of the device
After having resolved the cause of the error message, it is advisable to carry out a resetting of the errors (see P. 14).
In case of problems you can consult our After-Sales Department whilst indicating the identification N° located on one
of the sides of the micro-watt box (example: 5L8459).

Description/cause
The regulator has detected an excessive output current (above the program-
med limit value):
- Terminals U, V, W under short circuit, motor cable under short-circuit,
- poor motor wiring or star/delta coupling,
- Motor is blocked or sharp increase in load,
Compatibility regulator/ motor (compatible motor power).
The motor has absorbed current that is too high for a certain time.
- A mechanical friction increases the motor load,
- Rated current of the motor is higher than the converter's protection current,
- Compatibility between the converter and motor
- An unconnected wire in the motor terminal block.
The mains network voltage is too low or unstable
- Check the tightening of nuts and bolts (filter, proximity disconnecting switch, converter)
- Short network power supply current interruptions
- Defective contactors
The regulator is protected against earth leakage currents whenever it is connected
to the mains network voltage and no operating order has been given.
- An input has been programmed with the "USP" function and the latter is active.
The power supply voltage is greater than the device's rated voltage
Processor operating error
Error in reading the parameters stored in the device's memory
- Temperature too high
The device has detected an over-temperature
- Lack of ventilation for the micro-watt box
- Internal cooling fan for the defective regulator
