Check loading on motor 3. Load must match In certain cases apply braking resistor. Increase ramp down times Note: Load must match In certain cases apply braking resistor — A Vdc-max controller active Vdc max controller is active; so ramp- down times will be increased automatically to keep DC-link voltage r within limits P 1. Hi inverfer I have fault F on micromaster Parameter settings for output do not correspond to Micromasfer type.

P Motor i2t overload warning level should be set to suitable level 3. Load duty cycle must lie within specified limits 2. Check whether the motor is obstructed or overloaded.

Cycle the power to the drive. Have you any thoughts? Run self test routines 2. Reading of the powerstack information has failed or the data is invalid. Check motor parameters correspond to motor attached 3.

I remove the power cable of the motor but no use. Check that boost settings are not too high. Change inverter if repeated OFF2 F Communicatio ns board setpoint error No setpoint received from communications board during telegram off time 1. Change value of Mocromaster 2. Check whether the motor parameters correspond with the motor being used 5.

We have checked the motor settings and reset some parameters but the incorrect flashing screen is defeating us. Check parameter inverter input voltage 2.

Fan must turn when inverter is running 2. I need help to resolve our MM inventor problem. Inverter may run but certain actions will not function correctly 2. So how to reset that I reset it inberter times by turn off the breaker but when i turn it ON still F is coming on the display.

Inberter did see fault messages F and AO which could be a variety of faults. Our MM flashes between 6 and 00 when it should flash between 1 and 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.

Check that the cable length limits have not been exceeded 3. I have fault F on micromaster Vdc max controller miicromaster active; so ramp- down times will be increased automatically to keep DC-link voltage r within limits P Ramp-down time P must match inertia of load.

Air inlet and outlet points are not obstructed Ambient temperature could be higher than specified for the inverter. Via Digital Input 3 default setting. Check motor cable and motor for short- circuits and earth faults 4.

Motor parameters must match the motor in use 5.
