Chapter 10 Troubleshooting

The following table describes Bulletin 284E Faults as seen in Parameters 107,

108, and 109 (Fault 1, 2 or 3).

Table 39 - Bulletin 284E Faults – Parameters 107, 108, and 109 (Fault 1, 2 or 3)

No. Fault

Type

➊ Description Action

F2 Auxiliary Input 1 Auxiliary input interlock is open. 4. Check remote wiring.

5. Verify communications.

F3 Power Loss 2 DC bus voltage remained below 85% of

nominal.

6. Monitor the incoming AC line for low voltage or line power interruption.

7. Check input fuses.

F4 UnderVoltage 1 DC bus voltage fell below the minimum

value.

8. Monitor the incoming AC line for low voltage or line power interruption.

F5 OverVoltage 1 DC bus voltage exceeded maximum

value.

9. Monitor the AC line for high line voltage or transient conditions. Bus overvoltage can also

be caused by motor regeneration. Extend the decel time or install dynamic brake option.

F6 Motor Stalled 1 Drive is unable to accelerate motor. 10. Increase Parameters 139 or 167 (Accel Time x) or reduce load so drive output current does

not exceed the current set by Parameter 189 (Current Limit 1).

F7 Motor Overload 1 Internal electronic overload trip 11. An excessive motor load exists. Reduce load so drive output current does not exceed the

current set by Parameter 133 (Motor OL Current).

12. Verify Parameter 184 (Boost Select) setting

F8 Heatsink OvrTmp 1 Heatsink temperature exceeds a

predefined value.

13. Check for blocked or dirty heat sink fins. Verify that ambient temperature has not

exceeded 40°C.

14. Replace internal fan.

F12 HW OverCurrent 2 The drive output current has exceeded

the hardware current limit.

15. Check programming. Check for excess load, improper programming of Parameter 184

(Boost Select), DC brake volts set too high, or other causes of excess current.

F13 Ground Fault 2 A current path to earth ground has been

detected at one or more of the drive

output terminals.

16. Check the motor and external wiring to the drive output terminals for a grounded

condition.

F33 Auto Rstrt Tries Drive unsuccessfully attempted to reset a

fault and resume running for the

programmed number of Parameter 192

(Auto Rstrt Tries).

17. Correct the cause of the fault and manually clear.

F38

F39

F40

Phase U to Gnd

Phase V to Gnd

Phase W to Gnd

2 A phase to ground fault has been

detected between the drive and motor in

this phase.

18. Check the wiring between the drive and motor.

19. Check motor for grounded phase.

20. Replace starter module if fault cannot be cleared.

F41

F42

F43

Phase UV Short

Phase UW Short

Phase VW Short

2 Excessive current has been detected

between these two output terminals.

21. Check the motor and drive output terminal wiring for a shorted condition.

22. Replace starter module if fault cannot be cleared.

F48 Params Defaulted 2 The drive was commanded to write

default values to EEPROM.

23. Clear the fault or cycle power to the drive.

24. Program the drive parameters as needed.

F63 SW OverCurrent 2 Programmed Parameter 198 (SW Current

Trip) has been exceeded.

25. Check load requirements and Parameter 198 (SW Current Trip) setting.

F64 Drive Overload 2 Drive rating of 150% for 1 min. or 200%

for 3 sec. has been exceeded.

26. Reduce load or extend Accel Time.

F70 Power Unit 2 Failure has been detected in the drive

power section.

27. Cycle power.

28. Replace starter module if fault cannot be cleared.

F80 SVC Autotune The autotune function was either

cancelled by the user or failed.

29. Restart procedure.
