A blog we posted earlier this week about the Micromaster troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 402 and Alarms directly available.
Hopefully, this helps with your troubleshooting. NOTE To reset the fault code, one of three methods listed below can be used: Cycle the power to the drive.
Via Digital Input 3 default setting. Our MM flashes between 6 and 00 when it should flash between 1 and It has also taken to stopping after a few minutes intermittently. We did see fault messages F and AO which could be a variety of faults.
We have checked the motor settings and reset some parameters but the incorrect flashing screen is defeating us. Have you any thoughts? I need help to resolve our MM inventor problem.
How to maintenance about inverter showing f what happend end never change from monitor. Mm has A and F even without a sign for this kind of alarm…How to remove A and F alarm? I have fault F on micromaster So how to reset that I reset it many times by turn off the breaker but when i turn siemejs ON still F is coming on the display. I remove the power cable of the motor but no use. Your email micromastsr will not be published.

Motor power P must correspond to inverter power P 2. Cable length limits must not be exceeded 3. Motor cable and motor must have no short- circuits or earth faults 4. Motor parameters must match the motor in use 5. Value of stator resistance P must be correct 6. Supply voltage P must lie within limits indicated on rating plate 2. DC-link voltage controller must be enabled P and parameterized properly 3. Fan must turn when inverter is running 2. Pulse frequency must be set to default value 3.
Load duty cycle must lie within specified limits 2. Check motor data 2. Check loading on motor 3. Boost settings too high P,P, P 4. Check if the motor is connected to the inverter 2. Factory reset and new parameterization 2.
Change inverter if repeated OFF2 F Communicatio ns board setpoint error No setpoint received from communications board during telegram off time 1.

Check connections to the communications board 2. Run self test routines 2. Change value of P 2. Inverter may run but certain actions will not function correctly 2. Check whether the motor power corresponds to the inverter power 2. Check that the cable length limits have not been exceeded 3. Check motor cable and motor for short- circuits and earth faults 4. Check whether the motor parameters correspond with the motor being used 5.
Check the stator resistance 6. Increase the ramp-up-time 7.

Reduce the boost 8. Check that mains supply voltage is within allowable range 2. Increase ramp down times Note: Check if ambient temperature is within specified limits 2. Check load conditions and duty sidmens 3. P motor i2t time constant should be set to appropriate value miceomaster. P Motor i2t overload warning level should be set to suitable level 3. Are long periods of operation at low speed occuring 4. Input voltage P lies within range?
Load must match In certain cases apply braking resistor — A Vdc-max controller active Vdc max controller sjemens active; so ramp- down times will be increased automatically to keep DC-link voltage r within limits P 1. Check parameter inverter input voltage 2. Parameter settings for input do not correspond to ADC type Analogue input parameters should not be set to the same value as each other — A DAC parameters not set properly DAC parameters should not be set to identical values, since this would produce illogical results.
Check that load is applied to the inverter 2. Check motor parameters correspond to motor attached 3. Invetrer freezes the RFG output frequency at its current value. No output power to motor from mm fan not working neither.

Ramp-down time P must match inertia of load. Supply must not be susceptible to temporary failures or voltage reductions.
Air inlet and outlet points jicromaster not obstructed Ambient temperature could be higher than specified for the inverter.

Motor power P must match inverter power P Check parameter for motor I2t warning level. Check that the motor data has been entered correctly. Reading of the powerstack information has failed or the data is invalid. No setpoint received from communications board during telegram off time. Check whether the motor is obstructed or overloaded.
Vdc-max controller is active, ramp-down times will be automatically increased. Check if fan is turning when drive is running. Heatsink temperature and thermal junction model are outside of allowable range. Check that inverer settings are not too high. Load must match In certain cases apply braking resistor. Vdc max controller is active; so ramp- down times will be increased automatically to keep DC-link voltage r within limits P ADC parameters should not be set to identical values, since this would produce illogical results.
Parameter settings for input do not correspond to ADC sieemens.
Analogue input parameters should not be set to the same value as each other. DAC parameters should not be set to identical values, since this would produce illogical results.
Parameter settings for output do not correspond to DAC type. Analogue Output parameters should not be set to the same value as each other. As a result, some functions micromastet not work correctly, because there is no normal load condition.
