Check whether the motor is obstructed or overloaded. Check connections to the communications board 2. Parameter settings for input do not correspond to ADC type Analogue input parameters should not be set to inverger 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.

Motor power P must correspond to inverter power P 2. How to maintenance about inverter showing f what happend end never change from monitor. We also provide pre-priced Micromaster Repairs. This freezes the RFG output frequency at its current value. Inverter may run but certain actions will not function correctly 2. ADC parameters should not be set to identical values, since this would produce illogical results.

I have fault F on micromaster Check motor data 2. Air inlet and outlet points are not obstructed Ambient temperature could be higher than specified for the inverter. Input voltage P lies within range? View our Micromaster Drives in stock. Value of stator resistance Mixromaster must be correct 6.

Analogue Output parameters should not be set to the same value as each other.

Increase ramp down times Note: Vdc-max controller is active, ramp-down times will be automatically increased. Change inverter if repeated OFF2 F Communicatio ns board setpoint error No setpoint received from communications board during telegram off time 1. Check parameter for motor I2t warning level. Mm has A and F even without a sign for this kind of alarm…How to remove A and F alarm?

We did see fault messages F and AO which could be a variety of faults. Cycle the power to the drive. Analogue input parameters should not be set to the same value as each other. Ramp-down time P must match inertia of load.
