As a part of listing all common faults in Common Faults in Masterdrives, here is discussion regarding F011
· Output for short circuit or earth fault · Long overload · Motor and converter power is mismatched · Faulty Output CT · Parameterization · Encoder circuit · CU · IGBT Remedies –· When F011 is triggered, r785 stores the value of the current at which the trip occurred, so this value can help in further checking · Sometimes this fault comes when you don’t parameterize drive properly. You need to understand application properly and set control mode accordingly. · High starting torque application can make this trip if V/F control mode is used –in such cases Vector control should be used (with or without Sensor) · Problem in Output CT can be checked using r832. To be double sure, you can just swap output cable so that you can conclude fault is in CT or actual current is high. Also check value in OFF condition, it should be zero in OFF condition · Sometimes, this fault can occur due to Encoder Feedback problem also · If fault cannot be reset, problem may be in CU or Power board or IVI. Only thing to check this is by replacing the board itself · IGBT can be checked using Simulation mode of the drive or sometimes even comparing output current in all phases · In one case, we found F011 just came after F029. In that DC voltage in r006 was showing 540V when we gave only 24 V supply – not 3 Phase, Just removed Electronic box, cleaned drive completely then both fault just disappeared Regards, Devesh Vithani |

How to check encoder ?? Just check following post Trouble shooting in Vector Control Mode check why encoder feedback problem gives F011 fault ? Regards, Devesh Vithani |

Hello everyone I have a inverter simovrt masterdrive on the crane that makes an F011 error as soon as I get the joystick The work done : Replaced power supply card (PSU2) IVI card replaced 6 new IGBTs installed IGD replaced The set of C.Ts has been replaced Encoder cables were tested and the encoder was replaced The motor and its cables were tested with Megger and another electric motor was used to ensure However, it still drives F011 Thank you for your help in this regard |
