"Siemens micromaster 440 fault codes" indicate an problem in drive comes when hardware issue in control card, power card, incorrect input and output wiring or control wiring and incorrect parameter like start/stop and motor data.
Below list shows siemens micromaster 440 fault codes:
-
F0001: Overcurrent - This fault occurs when the drive detects that the current drawn by the motor exceeds the set limit.
-
F0002: Overvoltage - This indicates that the DC bus voltage in the drive has exceeded the maximum allowed value.
-
F0003: Undervoltage - The opposite of overvoltage, this fault means the DC bus voltage has dropped below the minimum acceptable level.
-
F0004: Overtemperature - The drive has detected that its internal temperature has exceeded safe operating limits.
-
F0011: Motor Over Temperature - The drive has detected that its motor temperature has exceeded safe operating limits.
-
F0012: Inverter temp. signal lost - Wire breakage of inverter temperature (heatsink) sensor.
-
F0020: Main Phase Missing - Fault occurs if one of the three input phases are missed and the pulses are enabled and drive is loaded.
-
F00021: Earth Fault - Fault occurs if the sum of the phase currents is higher than 5 % of the nominal inverter current.
-
F0022: Hardware Monitoring Fault - This fault comes when hardware issue in drive power card or control card.
-
F0023: Output Fault - One phase of output is disconnected.
