This freezes the RFG output frequency at its current value. DC-link voltage controller must be enabled P and parameterized properly 3.

Check motor cable and motor for short- circuits and earth faults 4. Value of stator resistance P must be correct 6. 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 Faults and Alarms directly available. DAC parameters should not be set to identical values, since this would produce illogical results.

We did see fault messages F and AO which could be a variety of faults. Inverter may run but certain actions will not function correctly 2. Motor parameters must match the motor in use 5. Hi all I have fault F on micromaster Check if fan is turning when drive is running. Check the stator resistance 6. Input voltage P lies within range? Check loading on motor 3.

Ramp-down time P must match inertia of load. Hopefully, this helps with your troubleshooting. Change value of P 2. Check that boost settings are not too high. Check connections to the communications board 2. Check if ambient temperature is within specified limits 2. I have siemejs F on micromaster Boost settings too high P,P, Micro,aster 4. Run self test routines 2. Check motor data 2. Motor cable and motor must have no short- circuits or earth faults 4.

Heatsink temperature and thermal junction model are outside of allowable range. I need help to resolve our MM inventor problem. It has also taken to stopping after a few minutes intermittently. Check whether the motor parameters correspond with the motor being used 5. As a result, some functions may not work correctly, invrrter there is no normal load condition. Invertef have checked the motor settings and reset some parameters but the incorrect flashing screen is defeating us.

P Motor i2t overload warning level should be set to suitable level 3. Leave a Reply Cancel reply Your email address will not be published. Check motor parameters correspond to motor attached 3. Reading of the powerstack information has failed or the data is invalid. Supply must not be susceptible to temporary failures or voltage reductions. Vdc max controller is active; so ramp- down times will be increased automatically to keep DC-link voltage r within limits P Your email address will not be published.

Load duty cycle must lie within specified limits 2. Check that the cable length limits have not been exceeded 3.

Have you any thoughts? No output power to motor from mm fan not working neither. Please how to replace motor of dishwasher Siemens lady Air inlet and outlet points are not obstructed Ambient temperature could be higher than specified for the inverter.

Siemens Micromaster Drive Faults and Alarms

P motor i2t time constant should be set to appropriate value 2. Check load micromasterr and duty cycle mjcromaster. Factory reset and new parameterization 2. We also provide pre-priced Micromaster Repairs. Via Digital Input 3 default setting. Fan must turn when inverter is running 2. Motor power P must correspond to inverter power P 2. ADC parameters should not be set to identical values, since this would produce illogical results. Vdc-max controller is active, ramp-down times will be automatically increased.

Motor power P must match inverter power P Parameter settings for output do not correspond to DAC type. No setpoint received from communications board during telegram off time. Check parameter for motor I2t warning level.
