Parker AC890 Drive Fault Codes:
| Fault Code | Cause & Solution |
|---|---|
| DCHI OVERVOLTAGE | Cause: The drive internal dc link voltage is too high Solution: – The supply voltage is too high – Trying to decelerate a large inertia load too quickly – The brake resistor is open circuit |
| DCLO UNDERVOLTAGE | Cause: The drive internal dc link voltage is too low. Solution: – The supply voltage is too low – The supply has been lost – A supply phase is missing |
| OC OVERCURRENT | Cause: The motor current being drawn from the drive is too high Solution: – Trying to accelerate a large inertia load too quickly – Trying to decelerate a large inertia load too quickly – Application of shock load to motor – Short circuit between motor phases – Short circuit between motor phase and earth – Motor output cables too long or too many parallel motors connected to the drive – Fixed or auto boost levels are set too high |
| STO SAFE TORQUE OFF | Cause: Safe Torque Off (STO) is active. Solution: – One or both STO user inputs is low – A fault has been detected in the STO circuit |
| HOT HEATSINK | Cause: The drive heatsink temperature is too high Solution: – The ambient air temperature is too high – Poor ventilation or spacing between drives |
| ET EXTERNAL TRIP | Cause: User trip caused via control terminals. Solution: – +24V not present on external trip (terminal X15/05) – Check setting of EXT TRIP MODE parameter |
| IN 1 INPUT 1 BREAK | Cause: I/O TRIPS:: INPUT 1 BREAK has gone True. Solution: – Check configuration to determine source of signal |
| IN 2 INPUT 2 BREAK | Cause: I/O TRIPS:: INPUT 2 BREAK has gone True. Solution: – Check configuration to determine source of signal |
| STLL MOTOR STALLED | Cause: The motor has stalled (not rotating). Solution: – Motor loading too great – Current limit level is set too low – Stall trip duration is set too low – Fixed or auto boost levels are set too high |
| IT INVERSE TIME | The inverse time current limit is active: motor loading is too great; fixed or auto boost levels are too high (Full Load Current = 150% for 60 seconds). |
| DB R BRAKE RESISTOR | Cause: External dynamic braking resistor has been overloaded. Solution: – Trying to decelerate a large inertia load too quickly or too often |
| DB S BRAKE SWITCH | Cause: Internal dynamic braking switch has been overloaded. Solution: – Trying to decelerate a large inertia load too quickly or too often. |
| DISP OP STATION | Cause: Keypad has been disconnected from drive whilst drive is running in local control Solution: – Keypad accidentally disconnected from drive |
| SCI COMMS BREAK | COMMS BREAK parameter set to True (refer to I/O TRIPS menu at level 3) |
| CNTC CONTACTOR FBK | The CONTACTOR CLOSED input in the SEQUENCING LOGIC function block remained FALSE after a run command was issued. |
| SPD SPEED FEEDBACK | SPEED ERROR > 50.00% for 10 seconds. |
| AOT AMBIENT TEMP | The ambient temperature in the drive is too high. |
| OT MOTOR OVERTEMP | Cause: The motor temperature is too high. Solution: – Excessive load – Motor voltage rating incorrect – FIXED BOOST and/or AUTO BOOST set too high – Prolonged operation of the motor at low speed without forced cooling – Check setting of INVERT THERMIST parameter in I/O TRIPS menu at level 3. – Break in motor thermistor connection |
| I HI CURRENT LIMIT | Cause: V/Hz mode only- If the current exceeds 180% of induction stack rated current for a period of 1 second, the drive will trip. This is caused by shock loads. Solution: – Remove the cause of the shock load. |
| A24SC 24V FAILURE | Cause: The 24V customer output has fallen below 17V Solution: – 24V customer output is short circuited – Excessive loading |
| LSPD LOW SPEED OVER I | Cause: The motor is drawing too much current (>100%) at zero output frequency. Solution: – FIXED BOOST and/or AUTO BOOST set too high (refer to FLUXING menu at level 3). |
| PHAS PHASE FAIL | One or more input phases not present. |
| ENC 1 FBK ENCODER FAIL | Encoder fault |
| SHRT DESAT (OVER I) | Instantaneous overcurrent. Refer to OVERCURRENT in this table. |
| DCRP VDC RIPPLE | Cause: The dc link ripple voltage is too high. Solution: – Check for a missing input phase. |
| DBSC BRAKE SHORT CCT | Cause: Brake resistor overcurrent Solution: – Check brake resistance is not less than minimum value allowed – check wiring and brake resistor for earth faults |
| OSPD OVERSPEED | Speed feedback > 150% for 0.1 seconds. |
| ANIN ANALOG INPUT ERR | 4-20mA analog input current > 22mA could damage the input circuit. |
| DBCT INT DB RESISTOR | 1. Braking mode set to INTERNAL (future use only). – Set to EXTERNAL and connect an External Braking Resistor if braking is required. |
| TRIP UNKNOWN | An unknown trip – refer to Parker Hannifin Manufacturing |
| TR32 OTHER | Refer to OTHER in Appendix D: TRIPS STATUS. One or more trips have occurred with a Value greater than 32. See the list. |
| ATN1 MAX SPEED LOW | During Autotune the motor is required to run at the nameplate speed o f the motor. If MAX SPEED RPM limits the speed to less than this value, an error will be reported. – Increase the value of MAX SPEED RPM up to the nameplate rpm of the motor (as a minimum). – It may be reduced, if required, after the Autotune is complete. |
| ATN2 MAINS VOLTS LOW | The mains input voltage is not sufficient to carry out the Autotune. – Re-try when the mains have recovered. |
| ATN 3 NOT AT SPEED | The motor was unable to reach the required speed to carry out the Autotune. – Possible reasons include: motor shaft not free to turn; the motor data is incorrect |
| ATN4 MAG CURRENT FAIL | It was not possible to find a suitable value of magnetising current to achieve the required operating condition for the motor. – Check the motor data is correct, especially nameplate rpm and motor volts. – Also check that the motor is correctly rated for the drive. |
| ATN5 NEGATIVE SLIP F | Autotune has calculated a negative slip frequency, which is not valid. – Nameplate rpm may have been set to a value higher than the base speed of the motor. – Check nameplate rpm, base frequency, and pole pairs are correct. |
| ATN6 TR TOO LARGE | Cause: The calculated value of rotor time constant is too large. Solution: Check the value of nameplate rpm. |
| ATN7 TR TOO SMALL | Cause: The calculated value of rotor time constant is too small. Solution: Check the value of nameplate rpm. |
| ATN8 MAX RPM DATA ERR | Cause & Solution: This error is reported when the MAX SPEED RPM is set to a value outside the range for which Autotune has gathered data. Autotune gathers data on the motor characteristics up to 30% beyond “max speed rpm”. – If MAX SPEED RPM is later increased beyond this range, the drive had no data for this new operating area, and so will report an error. – To run the motor beyond this point it is necessary to re-autotune with MAX SPEED RPM set to a higher value. |
| STAC STACK TRIP | The drive was unable to distinguish between an overcurrent/desat or overvoltage trip. |
| ATNA LEAKGE L TIMEOUT | Cause: The leakage inductance measurement requires a test current to be inserted into the motor. It has not been possible to achieve the required level of current. Solution: – Check that the motor is wired correctly. |
| PLOS POWER LOSS STOP | Power Loss Stop sequence has ramped Speed Setpoint to zero or timed out. |
| ATNC MOTR TURNING ERR | The motor must be stationary when starting the Autotune. |
| ATND MOTR STALLED ERR | The motor must be able to rotate during Autotune. |
| ATNE AT TORQ LIM ERR | The motor is in torque limit during Autotune. |
| ECAL FBK ENCODR CAL | Cause: The drive has failed to set absolute position Solution: – Check the encoder supports absolute position, and that the encoder is wired correctly. |

| CHRG CHARGING | Cause: Failed to charge DC link. – Excessive capacitance on DC link – Short circuit on DC link |
| DCRP VDC RIPPLE | Cause: Excessive DC link ripple Solution: – Driving a reciprocating load |
| AOUT ANOUT FAULT | Overload on analog output. |
| VOLT VOLTS SELECTION | Invalid position on volts selector switch. |
