Micromaster 440 Faults and Alarms

In the event of a failure, the inverter switches off and one of the following fault codes appear on the display.
FaultPossible CausesDiagnose & RemedyQuit
F0001
OverCurrent
- Motor power (P0307) does not correspond to the inverter power (r0206)
- Motor lead short circuit
- Earth faults
Check the following:
1. Motor power (P0307) must correspond to inverter power (r0206).
2. Cable length limits must not be exceeded.
3. Motor cable and motor must have no shortcircuits or earth faults
4. Motor parameters must match the motor in use
5. Value of stator resistance (P0350) must be correct
6. Motor must not be obstructed or overloaded
- Increase the ramp time
- Reduce the boost level
OFF2
F0002
OverVoltage
- DC-link voltage (r0026) exceeds trip level (P2172)
- Overvoltage can be caused either by too high main supply voltage or if motor is in regenerative mode. Regenerative mode can be cause by fast ramp downs or if the motor is driven from an active load.
Check the following:
1. Supply voltage (P0210) must lie within limits indicated on rating plate .
2. DC-link voltage controller must be enabled (P1240) and parameterized properly.
3. Ramp-down time (P1121) must match inertia of load.
4. Required braking power must lie within specified limits.
NOTE:
Higher inertia requires longer ramp times; otherwise, apply braking resistor.
OFF2
F0003
UnderVoltage
- Main supply failed.
- Shock load outside specified limits.
Check the following:
1. Supply voltage (P0210) must lie within limits indicated on rating plate.
2. Supply must not be susceptible to temporary failures or voltage reductions.
OFF2
F0004
Inverter Over
Temperature
- Inverter overloaded.
- Duty cycle too demanding.
- Motor power (P0307) exceeds inverter power capability (r0206).
Check the following:
1. Load duty cycle must lie within specified limits.
2. Motor power (P0307) must match inverter power (r0206)
OFF2
F0011
Motor Over
Temperature
- Motor overloaded Check the following:
1. Load duty cycle must be correct
2. Motor nominal overtemperatures (P0626-P0628) must be correct
3. Motor temperature warning level (P0604) must match
OFF1
F0012
Inverter temp.
signal lost
Wire breakage of inverter temperature (heatsink) sensorOFF2
F0015
Motor temperature
signal lost
Open or short circuit of motor temperature sensor. If signal loss is detected, temperature monitoring switches over to monitoring with the motor thermal model.OFF2
F0020
Mains Phase
Missing
Fault occurs if one of the three input phases are missed and the pulses are enabled and drive is loadedCheck the input wiring of the mains phasesOFF2
F0021
Earth fault
Fault occurs if the sum of the phase currents is higher than 5 % of the nominal inverter current.
NOTE - Framesizes D to F
This fault only occurs on inverters that have 3 current sensors.
OFF2
F0022
Powerstack fault
That hardware fault (P0947 = 22 and
P0949 = 1) caused by the following events:
(1) DC-link overcurrent = short circuit of IGBT
(2) Short circuit of chopper
(3) Earth fault
(4) I/O board is not poperly inserted.
- Framesizes A to C (1),(2),(3),(4)
- Framesizes D to E (1),(2),(4)
- FramesizeF(2),(4)
- Since all these faults are assigned to one signal on the power stack, it is not possible to establish which one actually occurred.
- UCE failure was detected, when P0947 = 22 and fault value P0949 =12 or 13 or 14, depending on UCE (for MegaMaster only)
Check the I/O board. It has to be fully pressed home. OFF2
F0023
Output fault
One phase of output is disconnectedOFF2
F0024
Rectifier Over
Temperature
- Ventilation inadequate
- Fan inoperative
- Ambient temperature is too high.
Check the following:
- Fan must turn when inverter is running
- Pulse frequency must be set to default value
- Ambient temperature could be higher than
specified for the inverter
OFF2
F0030
Fan has failed
Fan no longer working- Fault cannot be masked while options module
(AOP or BOP) is connected.
- Need a new fan.
