Parker AC650 Drive Fault Codes:
| Fault Code | Cause & Solution |
|---|---|
| 1 Over Voltage dCHI | The drive internal dc link voltage is too high: – The supply voltage is too high – Trying to decelerate a large inertia load too quickly, DECEL TIME too short, – The brake resistor is open circuit To help prevent this trip, enable the DC Link Volts Limit feature Internal dc link voltage has reached midway between the over voltage trip level and the dynamic braking resistor control voltage. |
| 2 Under Voltage dCLO | DC link low trip: – Supply is too low/power down Internal dc link voltage has reached midway between the lowest expected instantaneous voltage and the undervoltage trip level. |
| 3 OC Over Current | The motor current being drawn from the drive is too high: – Trying to accelerate a large inertia load too quickly; ACCEL TIME time too short – Trying to decelerate a large inertia load too quickly; DECEL TIME time too short – 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 BOOST level set too high The over current trip uses a multiple-attempt strategy. The warning is triggered if two or more consecutive overcurrent events are encountered (whereas five consecutive events are required for a Trip to occur). |
| HOt 4 HEATSINK | Drive heatsink temperature > 100ºC: – The ambient air temperature is too high Poor ventilation or spacing between drives. |
| 5 Et EXTERNAL TRIP | The external trip input is high: – Check configuration to identify the source of the signal (non-standard configuration). |
| It 6 INVERSE TIME | A prolonged overload condition, exceeding the Inverse Time allowance, has caused the trip: – Remove the overload condition |
| LOOP 7 CURRENT LOOP | A current of less than 1mA is present when 4-20mA setpoint is selected: – Look for a wire break. |
| 8 StLL MOTOR STALLED | The motor has stalled (not rotating) Drive in current limit >200 seconds: – Motor loading too great. – FIXED BOOST level set too high. |
| 9 t3 ANIN FAULT | AIN2 overload on terminal 3: – Overcurrent applied in Current mode to terminal 3. |
| 12 dISP DISPLAY KEYPAD | Keypad has been disconnected from drive whilst drive is running in Local Control: – Keypad accidentally disconnected from drive (indicated over Comms, or by second keypad). |
| 13 SCI / SC1 LOST COMMS | Lost communications: – COMMS TIMEOUT parameter set too short – Master device failed – Wiring broken – Incorrect Comms setup |
| 14 CnTC CONTACTOR FBK | Contactor feedback signal lost: – Check connection to the terminal wired to “contactor closed” parameter in Sequencing Logic (non-standard configuration). |
| 17 Ot 17 MOTOR OVERTEMP | The motor temperature is too high: – Excessive load – Motor voltage rating incorrect – FIXED BOOST level set too high – Prolonged operation of the motor at low speed without forced cooling – Break in motor thermistor connection |
| 18 IHI / 1H1 CURRENT LIMIT | Software overcurrent trip: – If the current exceeds 180% of stack rated current for a period of 1 second, the drive will trip. This is caused by shock loads. Remove the shock load. – ACCEL TIME and/or FIXED BOOSTset too high – DECEL TIME set too low |
| 21 LSPD LOW SPEED OVER I | The motor is drawing too much current (>100%) at zero output frequency: – FIXED BOOST level set too high. |
| 22 t4 10V FAULT | 10V fault: – +10V REF overload warning (terminal 4) – 10mA maximum. |
| 24 ShTt / Shft DESATURATION | Desaturation: – Instantaneous overcurrent. Refer to OVERCURRENT in this table. |
| 25 DCTP DC LINK RIPPLE | The dc link ripple voltage is too high: – Check for a missing input phase. |
| 26 dbSC BRAKE SHORT CCT | Brake resistor overcurrent: – Check brake resistor value is greater than minimum allowed. |
| 28 t5 ANOUT FAULT | AOUT overload on terminal 5: – 10mA maximum. |
| 29 t9 DIGIO 1 (T9) FAULT | DIN3 overload on terminal 9: – 20mA maximum. |
| 30 t10 DIGIO 2 (T10) FAULT | DOUT2 overload on terminal 10: – 50mA maximum. |
| 31 tTIP UNKNOWN | Unknown trip |
| 33 ICAL | Zero I Current Calibration: – Current sensor calibration fault. Switch unit off/on. If persistent, return to factory. |
| CODE | Product Code Error Switch unit off/on. – If persistent, return unit to factory |
| CAL Calibration Data Error | Switch unit off/on. – If persistent, return unit to factory |
| dAtA Configuration Data | Error Press “E” the key to accept the default configuration. – If persistent, return unit to factory |
