9. TROUBLESHOOTING
Alarm code
Alarm name
Alarm description
OC1
Overcurrent protection
during acceleration
Excessive output current due to:
-
Excessive motor load.
-
Acceleration (deceleration) too fast.
-
Short circuit in the output circuit.
-
Ground fault (this protection is effective only during start
up).
OC2
Overcurrent protection
during deceleration
OC3
Overcurrent protection
at constant speed
OU1
Overvoltage
protection
during acceleration
Voltage in the DC link too high (400 V for 200 V class inverters;
800 V for 400 V class inverters) due to:
-
Deceleration too fast.
-
The motor is regenerating energy and there is no braking
resistor connected to the inverter.
This protection may not protect the case where the supply voltage is
excessive
OU2
Overvoltage
protection
during deceleration
OU3
Overvoltage protection at
constant speed
LU
Undervoltage protection
Voltage in the DC link too low (200 V for 200 V class inverters;
400 V for 400 V class inverters).
Lin
Input
phase
loss
protection
Input phase loss.
If the inverter load is low or a DC reactor is installed the event of an
input phase loss may be not detected.
OPL
Output
phase
lost
protection
An output phase of the inverter is in open circuit.
OH1
Overheat protection
Excessive heat sink temperature due to:
-
Inverter fan is not working.
-
The inverter is overloaded.
