To clear a fault, press the Stop key, cycle power or set A100 [Fault Clear] to 1 or
2.

Fault Codes

No.

Fault

Description

F2

Auxiliary Input

(1)

Check remote wiring.

Verify communications programming for intentional fault.

F3

Power Loss

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

Check input fuses.

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 dynamic brake option.

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]. Verify A084 [Boost Select] setting.

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.

F29

Analog Input Loss

(1)

An analog input is configured to fault on signal loss. A signal loss has occurred.

Check parameters. Check for broken/loose connections at inputs.

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

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

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

Cycle power. Check communications cabling.

Check network adapter setting. Check external network status.

F80

SVC Autotune

The autotune function was either cancelled by the user of failed. Restart procedure.

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 A105 [Comm Loss Action].

Connecting I/O Terminal 04 to ground may improve noise immunity.

(1)

Auto-Reset/Run type fault. Configure with parameters A092 and A093.

Troubleshooting your Allen Bradley PowerFlex 40 AC drive begins with a fault condition that occurs while operating or starting up. The status of your drive is monitored at all times and any changes in the status will be indicated through the keypad. A fault is a condition that stops the drive and there are two types of fault conditions. The first being an auto-reset/run fault. When this type of fault occurs, user settings can be configured that will automatically restart the drive or even wait for a predetermined amount of time and then attempt a restart if the fault condition is no longer present. The second type of fault condition is a non-resetable fault. This type of fault is more of a major fault and may require more in-depth analysis or action such as drive or motor repair. It is also possibly caused by wiring or programming errors. The cause of the fault will have to be corrected before the fault can be reset and the drive started.

The following is a listing of the possible fault codes of the Allen Bradley PowerFlex 40 drive and short descriptions of the causes.

F2 Auxiliary Input – Auxiliary input interlock is open

F38 Phase U to Ground – A phase to ground fault has been detected in this phase
F39 Phase V to Ground – A phase to ground fault has been detected in this phase
F40 Phase W to Ground – A phase to ground fault has been detected in this phase
F41 Phase UV Short – Excessive current has been detected between these two output terminals
F42 Phase UW Short – Excessive current has been detected between these two output terminals
F43 Phase VW Short – Excessive current has been detected between these two output terminals
F48 Parameters Defaulted – Drive was commanded to write default values to EEPROM
