u Alarm and Error Displaysn FaultsTable 5.5 gives an overview of possible fault codes. Conditions such as overvoltages can trip faults and alarms. It is importantto distinguish between faults and alarms to determine the proper corrective actions.When the drive detects a fault, the ALM indicator LED lights, the fault code appears on the HOA keypad, and the fault contactMA-MB-MC triggers. An alarm is present if the ALM LED blinks and the fault code on the HOA keypad flashes. Refer toMinor Faults and Alarms on page 198 for a list of alarm codes.Table 5.5 Fault DisplaysHOAKeypadDisplay Name PagebAT Digital Operator Battery Voltage Low 200boL Braking Transistor Overload Fault 200bUS Option Communication Error 200CE MEMOBUS/Modbus Communication Error 200CPF11 toCPF14<1> <3> Control Circuit Error 201CPF16 toCPF19<1> <3> Control Circuit Error 201CPF02 A/D Conversion Error 201CPF03 Control Board Connection Error 201CPF06<3> EEPROM Memory Data Error 201CPF07,CPF08 Terminal Board Connection Error 201CPF20,CPF21<2> Control Circuit Error 201CPF22 Hybrid IC Error 202CPF23 Control Board Connection Error 202CPF24<3> Drive Unit Signal Fault 202CPF25 Terminal Board Not Connected 202CPF26 toCPF35,CPF40 toCPF43Control Circuit Error 202CPF46 Terminal Board Error 202E5 SI-T3 Watchdog Timer Error 202EF0 Option Card External Fault 202EF1 to EF7 External Fault(input terminal S1 to S7) 203Err EEPROM Write Error 203FAn Internal Fan Fault 218FbH Excessive PID Feedback 204FbL PID Feedback Loss 204GF Ground Fault 204LF Output Phase Loss 205LF2 Current Imbalance 205nSE Node Setup Error 205oC Overcurrent 206HOAKeypadDisplay Name PageoFA00<3> Option Card Connection Error(CN5-A) 206oFA01 Option Card Fault (CN5-A) 207oFA03 tooFA06 Option Card Error(CN5-A) 207oFA10,oFA11 Option Card Error(CN5-A) 207oFA12 tooFA17 Option Card Connection Error(CN5-A) 207oFA30 tooFA43 Comm Option Card Connection Error(CN5-A) 207oH Heatsink Overheat 208oH1 Heatsink Overheat 208oH3 Motor Overheat Alarm (PTC input) 208oH4 Motor Overheat Fault (PTC input) 222oL1 Motor Overload 209oL2 Drive Overload 209oL3 Overtorque Detection 1 210oL7 High Slip Braking oL 210oPr Operator Connection Fault 210ov Overvoltage 211ov2 Overvoltage 2 211PF Input Phase Loss 212rF Braking Resistor Fault 212rH Dynamic Braking Resistor 212rr Dynamic Braking Transistor 212SC IGBT Short Circuit or Ground Fault 212SEr Too Many Speed Search Restarts 213TdE Time Data Error 213TIE Time Interval Error 213TIM Time Not Set 213UL3 Undertorque Detection 1 214UL6 Motor Underload 214Uv1<3> Undervoltage 214Uv2<3> Control Power Supply Undervoltage 214Uv3<3> Soft Charge Circuit Fault 215voF Output Voltage Detection Fault 215<1> Displayed as CPF00 when occurring at drive power up.
