It has also taken to stopping after a few minutes intermittently. Increase the ramp-up-time 7.

Cycle the power to the drive. I remove the power cable of the motor but no use. Input voltage P lies within range?

Factory reset and new parameterization 2. Run self test routines 2. Cable length limits must not be exceeded 3. Hi all I have fault F on micromaster Analogue Output parameters should not be set to the same value as each other.

Check that load is applied to the inverter 2. I need help to resolve our MM inventor problem. Load duty cycle must lie within specified limits 2. Check loading on motor 3.

DAC parameters should not be set to identical values, since this would produce illogical results. Reading of the powerstack information has failed or ingerter data is invalid. Check the stator resistance 6. Leave a Reply Cancel reply Your email address will not be published. Check whether the motor parameters correspond with the motor being used 5. Boost settings too high P,P, P 4. Our MM flashes between 6 and 00 when it should flash between 1 and Ramp-down time P must match inertia of load.

Fan must turn when inverter is running 2. Check that boost settings are not too high. We have checked the motor settings and reset some parameters but the incorrect flashing screen is defeating us. A blog we posted earlier this week about the Micromaster micromasted 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 4200 Alarms directly available.

This freezes the RFG output frequency at its current value. Your email address will not be published. P Motor i2t overload warning level should be set to suitable level 3. Parameter settings for input do not correspond to ADC type Analogue input parameters should not be set to the invertr 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.

Parameter settings for output do not correspond to DAC type. Motor parameters must match the motor in use 5.

Motor cable and motor must have no short- circuits or earth faults 4. Air inlet and outlet points are not obstructed Ambient temperature could be higher than specified for the inverter. Ingerter output power to motor from mm fan not working neither.

Supply must not be susceptible to temporary failures or voltage reductions.

Parameter settings for input do not correspond to ADC type. Check that the cable length limits have not been exceeded 3.

Check connections to the communications board 2. As a result, some functions may not work correctly, because there is no normal load condition. Check whether the motor power corresponds to the inverter power 2. NOTE To reset the fault code, one of three methods listed below can kicromaster used: Via Digital Input 3 default setting.

We did see fault messages F and AO which could be a variety of faults. Change inverter if repeated OFF2 F Communicatio ns board setpoint error No setpoint received from communications board during telegram off time 1. Load must match In certain cases apply braking resistor. Heatsink temperature and thermal junction model are outside of allowable range.

Motor power P must match inverter power P Mm has A and F even without a sign for this kind of alarm…How to remove A and F alarm?

Check motor cable and motor for short- circuits and earth faults 4. Analogue input parameters should not be set to the same value as each other.

Check that the motor data has been entered correctly. Micromster voltage controller must inerter enabled P and parameterized properly 3. ADC parameters should not be set to identical values, since this would produce illogical results. Check parameter inverter input voltage 2.
