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.| Fault | Possible Causes | Diagnose & Remedy | Quit |
|---|---|---|---|
| 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 |

It has to be fully pressed home. | OFF2 |
| F0023 Output fault | One phase of output is disconnected | OFF2 | |
| 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 |
