Short description of the error
Troubleshooting
2
✓
Phase error
(Phase er)
The motor phase U, V or W is broken (not
connected) or high current asymmetry on
the motor.
Check the cabling and connections
between the equipment and the motor.
2
Brake overload
(Brake ov)
Based on its adjusted data, the braking
resistor load is high.
• increasing the run off time,
• check (value of R, its loadability,
• installing a resistor with higher
loadability.
2
✓
Line phase error
(Line pha)
One of the input phase voltages is either
failing or abnormally smaller than the
others.
Check the availability of the three phases
and network wiring and connections.
2
✓
Uphase overcurr.
(Uphase o)
The U phase output of the frequency
converter is overloaded, that is I motor
Uphase> I inverter max.
• reducing the load,
• installing a frequency converter with
higher power.
2
✓
Vphase overcurr.
(Vphase o)
The V phase output of the frequency
converter is overloaded, that is I motor
Vphase> I inverter max.
2
✓
Wphase overcurr.
(Wphase o)
The W phase output of the frequency
converter is overloaded, that is I motor
Wphase> I inverter max.
3
✓
Heatsink hot
(Heats.ho)
The measured temperature of the heatsink
is too high
Check:
• in case of built in ventilator, above
45C the rotation of the ventilator
• if mounted in rack, the ventilation of
the rack
• the load of the equipment
4
✓
IGBT prot.
(IGBTprot)
The IGBT module indicated an error. A
typical phenomenon of output shorting.
Check the cabling and connections
between motor and equipment
4
✓
HW voltage prot.
(HWvoltage)
Intermediate DC voltage has reached the
maximum HW inhibit limit or the charging
relay is not pulled
• network interference filtering,
• phase correction
4
Charge relay err
(Ch.relay)
The charging relay is not pulled.
Internal error. The manufacturer is
required to troubleshooting.
4
✓
DC overvoltage
(DC ov.v.)
The intermediate DC voltage raised above
the permitted limit.
If there is phase correction in front of the
equipment:
• Connecting a mains choke in front of
the unit.
If it occurs during run down:
• increasing the run down time
4
✓
DC volt. curly
(DC curly)
The DC voltage is overloaded or the mains
voltage is too low.
• reducing the load,
• slower run up and run down
4
✓
DC error
(DC erro)
The intermediate circuit capacitor cannot
be charged.
Internal error. (e.g. capacitor short circuit)
The manufacturer is required to
troubleshooting.
4
✓
Thyristor com.e.
(Thyrist.)
Communication error between the thyristor
controller and the drive control processor.
Check the internal connecting cable.
4
✓
Break IGBT prot.
(Br. IGBT)
The brake module indicates IGBT error.
Check the brake resistor (e.g. short
circuit).
5
Overfrequency
(Overfreq)
Due to the load on the side of the load, the
frequency exceeded the permitted value (f
inhibit).
Modification of the settings.
5
Overfrequency
(Overfreq)
The measured rotation speed is greater
than the maximum rotation speed
calculated from the nominal motor speed
and the ratio of the nominal frequency and
the frequency inhibit limit.
Check:
• IRE parameters(menu 4-31)
• frequency inhibit limit (menu 8-3)
• motor parameters (menu 6)
