Chapter 4 Troubleshooting
F12 HW OverCurrent 2 The drive output current has
exceeded the hardware current limit. Check programming. Check for
excess load, improper
A170 [Boost
Select] setting, 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. Check the motor and external wiring
to the drive output terminals for a
grounded condition.
F15 Load Loss 1 Output current has dropped below
the level set in
A184 [Load Loss
Level].
Check for load loss (i.e., a broken
belt).
F17 Input Phase Loss
(FRN 6.xx and
later) 2 Excessive DC bus ripple voltage
detected. See
d329 [DC Bus Ripple
V].
Check incoming power for a missing
phase or blown fuse. If drive is used
intentionally with single phase
input, apply output derating to 35%
actual drive rating.
F29 Analog Input
Loss 1 An analog input is configured to fault
on signal loss. A signal loss has
occurred.
Configure with
T072 [Anlalog In
Loss].
1. Check parameters.
2. Check for broken/loose
connections at inputs.
F32 Fan Fdbck Loss
(FRN 6.xx and
later) 2 A loss of cooling fan feedback has
been detected. (Frames E and F only Make sure cooling fans are clear of
debris and spinning freely. Replace
fan if necessary.
F33 Auto Rstrt Tries 2 Drive unsuccessfully attempted to
reset a fault and resume running for
the programmed number of
A163
[Auto Rstrt Tries].
Correct the cause of the fault and
manually clear.
F38 Phase U to Gnd 2 A phase to ground fault has been
detected between the drive and
motor in this phase. 1. Check the wiring between the
drive and motor.
2. Check motor for grounded phase.
3. Replace drive if fault cannot be
cleared.
F39 Phase V to Gnd
F40 Phase W to Gnd
F41 Phase UV Short 2 Excessive current has been detected
between these two output terminals. 1. Check the motor and drive
output terminal wiring for a
shorted condition.
2. Replace drive if fault cannot be
cleared.
F42 Phase UW Short
F43 Phase VW Short
F48 Params
Defaulted The drive was commanded to write
default values to EEPROM. 1. Clear the fault or cycle power to
the drive.
2. Program the drive parameters as
needed.
F63 SW OverCurrent 1 Programmed A183 [SW Current Trip]
has been exceeded.
Check load requirements and A183
[SW Current Trip] setting.
F64 Drive Overload 2 Drive rating of 110% for 1 minute or
150% for 3 seconds has been
exceeded. Reduce load or extend Accel Time.
F70 Power Unit 2 Failure has been detected in the drive
power section. 1. Cycle power.
2. Replace drive if fault cannot be
cleared.
F71 Net Loss The communication network has
faulted. 1. Cycle power.
2. Check communications cabling.
3. Check network adapter setting.
4. Check external network status.
