Abbreviated List of Micromaster Faults

[aaronw]

Anyone have an abbreviated list of faults for the Micromaster drives or motor controllers? Having some issues, looking for a list of micromaster faults.

Here's a list of fault codes for Micromaster drives, not sure if it is model specific. It's the fault code, possible causes, and corrective actions.

F001 Overvoltage: Check whether supply voltage is within the limits indicated on the rating plate or Increase the ramp down time (P003) or Check whether the required braking power is within the specified limits.

F002 Overcurrent: Check whether the motor power corresponds to the inverter power or Check that the cable length limits have not been exceeded or Check motor lead and motor for short-circuits and earth faults. Also Check whether the motor parameters (P081 - P086) correspond with the motor being used. Check the stator resistance (P089). Try Increasing the ramp-up time (P002). Also Reduce the boost set in P078 and P079 and check whether the motor is obstructed or overloaded.

F003 Overload: Check whether the motor is overloaded or Increase the maximum motor frequency if a motor with high slip is used.

F005 Inverter overtemperature (internal heatsink sensor): Check that the ambient temperature is not too high or Check that the air inlet and outlet are not obstructed or Check that the integral fan is working.

F008 USS protocol timeout: Check the serial interface or Check the settings of the bus master and P091 - P093 or Check whether the timeout interval is too short (P093).

F010 Initialization fault / Parameter loss: * Check the entire parameter set. Set P009 to `0000' before powering down.

F011 Internal interface fault: * Switch off power and switch on again to clear.

F012 External trip (PTC): Check if motor is overloaded.

F013 Programme fault: * Switch off power and switch on again.

F030 PROFIBUS link failure: Check the integrity of the link.

F031 Option module to link failure: Check the integrity of the link.

F033 PROFIBUS Configuration error: Check the PROFIBUS configuration.

F036 PROFIBUS module watchdog: trip Replace PROFIBUS module

F074 Motor overtemperature by I2t calculation: Trip occurs only if P074 = 4, 5, 6 or 7. Check that the motor current does not exceed the value set in P083 and P086.

F075 Over current during ramping down: Increase the ramp down time (P003).

F101 Internal interface fault: * Switch off power and switch on again.

F105 Inverter overtemperature (internal sensor): Check that the ambient temperature is not too high or Check that the air inlet and outlet are not obstructed or Check that the inverter's integral fan is working

F106 Parameter fault P006: Parameter is fixed frequency(ies) and/or motor potentiometer on the digital inputs.

F112 Parameter fault P012/P013: Set parameter P012 < P013.

F151 Digital input parameter fault: Check the settings of digital input P051 to P053.

F152 Digital input parameter fault: Check the settings of digital inputs P051 to P053.

F153 Digital input parameter fault: Check the settings of digital inputs P051 to P053.

F201 P006 = 1 while P201 = 2: Change parameter P006 and/or P201.

F212 Parameter fault P211/P212: Set parameter P211 < P212.

F231 Output current measurement imbalance: See F002

F255 Watchdog Trip: Remove prime power and re-apply
