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.
