Parker AC10 Drive Fault Codes:
| Fault Code | Cause & Solution |
|---|---|
| AErr | Line Disconnected – Analog signal line disconnected – Signal source is broken – Change the signal line – Change the signal source |
| CE Communication Timeout | Communication fault – PC/PLC does not send command at fixed time – Check communication line for reliable connected |
| Err1 Password is Wrong | Cause: Password is Wrong. Solution: – When password function is enabled, password is set wrong – Set password correctly |
| Err2 Tuning Parameters Wrong | Cause: Tuning Parameters Wrong Solution: – incorrect motor parameters entered – Connect motor correctly – Enter correct motor data |
| Err3 Current Malfunction Before Running | Cause: Current MalfunctionBefore Running. Solution: – Current alarm signal exists before running – Check if control board is properly connected to power board |
| Err4 Current Zero Excursion Malfunction | Cause: Current Zero Excursion Malfunction. Solution: – Flat cable is loosened – Current detector is broken – Check the flat cable |
| Err5 PID Parameters are set Wrong | Cause: PID Parameters are set Wrong. Solution: – PID parameters are set wrong. – Set the parameters correctly. |
| FL Flycatching Fault | Cause: FL Flycatching Fault. Solution: – Flycatching failure. – Track again. |
| GP Ground fault | Cause: GP Ground fault. Solution: – Motor cable is broken and short- circuit to earth – The insulation of motor is broken and short circuit to earth – Inverter has fault – Change motor cable – Repair or replace motor – SEE ALSO: OC, OC2 and ERR4 |
| L.U. / LU Under-Voltage | Cause: Under-Voltage Protection. Solution: – Low voltage on the input side – Check if supply voltage is normal – Check if parameter setting is correct |
| OC/OC2 Overcurrent | Cause: Overcurrent. – Too short acceleration time – Short circuit at output side – Locked rotor with motor – Parameter tuning is not correct – Prolong acceleration time – Ask if motor is cable broken – Check if motor overloads – Reduce VVVF compensation value – Measure parameter correctly |
| OC1 Overcurrent | Cause: Overcurrent. – Too short acceleration time – Short circuit at output side – Locked rotor with motor – Parameter tuning is not correct – Prolong acceleration time – Ask if motor is cable broken – Check if motor overloads – Reduce VVVF compensation value – Measure parameter correctly |
| O.E. / OE DC Over-Voltage | Cause: DC Over-Voltage. – Supply voltage too high – Load inertia too big – Deceleration time too short – Motor inertia rise again – Parameter of speed loop PID is set abnormally Solution: – Check if rated voltage is input – Add braking resistance(optional) – Increase deceleration time – Set the parameter of rotary speed loop PID correctly |
| O.H. / OH Heatsink Overheat | Cause: – Environment temperature too high – Poor ventilation – Fan damaged – Carrier wave frequency or compensation curve is too high Solution: – Improve ventilation – Clean air inlet and outlet and radiator – Install as required – Change fan – Decrease carrier wave frequency or compensation curve |
| O.L1 / OL1 Inverter Overload | Cause & Solution: 1. Inverter Overload – Load too heavy – Reduce load; check drive ratio – Increase inverter’s capacity |
| O.L2 / OL2 Motor Overload | Cause & Solution: 1. Motor Overload. – Load too heavy – Reduce load: check drive ratio – Increase motor’s capacity |
| PCE PMSM tuning fault | Cause & Solution: PMSM tuning fault – Load is too heavy – Motor parameters measurement is wrong – Decrease the load – Measure motor parameters correctly |
| P.F1. / PF1 Input Phase Loss | Cause & Solution: Input Phase Loss. – Phase loss with input power – Check if power input is normal – Check if parameter setting is correct |
| PF0 Output Phase Loss | Cause & Solution: Output Phase Loss. – Motor is broken – Motor wire is loose – Inverter is broken – Check if wire of motor is loose – Check if motor is broken |
