Fault
Description
F2
Auxiliary Input
(1)
Check remote wiring.
F3
Power Loss
Monitor the incoming AC line for low voltage or line power interruption.
F4
UnderVoltage
(1)
Monitor the incoming AC line for low voltage or line power interruption.
F5
OverVoltage
(1)
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 a dynamic brake chopper.
F6
Motor Stalled
(1)
Increase [Accel Time x] or reduce load so drive output current does not exceed the current set
by parameter A089 [Current Limit].
F7
Motor Overload
(1)
An excessive motor load exists. Reduce load so drive output current does not exceed the
current set by parameter P033 [Motor OL Current].
F8
Heatsink OvrTmp
(1)
Check for blocked or dirty heat sink fins. Verify that ambient temperature has not exceeded 40
°
C
(104
°
F) for IP 30/NEMA 1/UL Type 1 installations or 50°C (122°F) for Open type installations.
Check fan.
F12
HW OverCurrent
Check programming. Check for excess load, improper DC boost setting, DC brake volts set too
high or other causes of excess current.
F13
Ground Fault
Check the motor and external wiring to the drive output terminals for a grounded condition.
F15
Load Loss
Check for load loss (i.e., a broken belt).
F29
Analog Input Loss
(1)
An analog input is configured to fault on signal loss. A signal loss has occurred.
F33
Auto Rstrt Tries
Correct the cause of the fault and manually clear.
F38
Phase U to Gnd
Check the wiring between the drive and motor. Check motor for grounded phase.
Replace drive if fault cannot be cleared.
F39
Phase V to Gnd
F40
Phase W to Gnd
F41
Phase UV Short
Check the motor and drive output terminal wiring for a shorted condition.
Replace drive if fault cannot be cleared.
F42
Phase UW Short
F43
Phase VW Short
Hoover SpinScrub 50 Instructions are available below. Hoover spin scrub 50 user manual.
F48
Allen Bradley
Params Defaulted
The drive was commanded to write default values to EEPROM. Clear the fault or cycle power to
the drive. Program the drive parameters as needed.
F63
SW OverCurrent
(1)
Check load requirements and A098 [SW Current Trip] setting.
F64
Drive Overload
Reduce load or extend Accel Time.
F70
Power Unit
Allen Bradley Powerflex 400 Drive
Cycle power. Replace drive if fault cannot be cleared.
F71
Net Loss
Powerflex 400 Drive Manual
The communication network has faulted.
F81
Comm Loss
If adapter was not intentionally disconnected, check wiring to the port. Replace wiring, port
expander, adapters or complete drive as required. Check connection. An adapter was
intentionally disconnected. Turn off using C105 [Comm Loss Action].
F94
Function Loss
Close input to terminal 01 and re-start the drive.
F100 Parameter Checksum Restore factory defaults.
F122 I/O Board Fail
Cycle power. Replace drive if fault cannot be cleared.
(1)
Auto-Reset/Run type fault. Configure with parameters A092 and A093.
